Earth History

Earth History

Why?

Why do a chronology of major events in the Earth's history? Many timelines concerning the history of civilisation, including dates of battles and rulers, have been published, as have many good academic and reference books on changes in global climate, migration of land masses and so on. There is also much useful and thought-provoking material on the Web.

What interests me, however, is the vast expanse of time, BC, in which the recording of important events is patchy and increasingly elusive the further back one searches : a field of play where scientists, pseudoscientists and proponents of religious dogma enthusiastically and sometimes intolerantly vie to convince the world at large (and sometimes themselves) of their pet theory. Taken at face value the theory can be persuasive, but where dates are involved, how does it stack up against existing evidence and the arguments of others?

Where do the various myths and legends of prehistory fit in ? Could putting all the dates together in context give a new twist to the history of civilisation or pre-history?

The Bible alludes to actual historical events and leaders as well as being a vehicle for myth, prophecy, poetry and moral authority. For example, Noah' s Flood, which various scholars have attempted to date: was it truly global, or more of a regional - nonetheless devastating - event for the Middle Eastern chroniclers? A similar event features in other non Judeo-Christian traditions. Did they coincide with the disappearance of Atlantis?

Global warming is very much on our minds at present, but historical, geographical and biological evidence prove that the climate of Europe has been even warmer before. Are there parallels between dramatic climate change and mass extinctions?

It is no longer widely considered that the Earth has remained unchanged for millions of years. The biosphere is vulnerable because Earth is still active geologically; there are cycles of change within the Solar System, and unpredictable threats from comets and meteorites remain. Some of these have left their mark on Earth history from the fossil record to human civilisation.

The chronology records events which generally indicate that the Earth is much older than ancient peoples believed. Where is the evidence for this, and are the dating methods consistent? Well, the passage of the years and seasons are recorded in nature - in everything from stalactite growth layers to ice cores to pollen fossils to lake and sea deposition sediments - all are available to reveal that there have been tens of thousands of years of history beyond the limited scope of dendrochronology. And this is only the beginning....

This chronology started out as a personal attempt to contextualise a mass of information gleaned from reading, watching television or, latterly, surfing the Internet. It is therefore the flawed and incomplete chronology of an amateur. It is idiosyncratic; It is also 'work in progress'. I have not found anything quite like it anywhere else, and now I feel the time has come to put it out on the Internet.

Over to you - I welcome constructive suggestions and any further sourced information that may improve it.

Chronology A

Chronology A: Known and possible dates of major events in Earth history.


* All entries before 10,000 BC are in years Before Present (BP). Most dates are approximate, or rounded up, and may be adjusted as new discoveries come to light.

* For other abbreviations, see end of Chronology.

* Sources, including TV programmes, books and internet sites follow the list of abbreviations.

* LATEST UPDATE: July 2014

1. Cycles

every 500 million years:
Approximate period in which super continents have formed and broken apart (In Our Time: The Geological Formation Of Britain, Radio 4, 22/10/09).

every
237 m yrs:
Sun orbits our galaxy.

every
30 m yrs:
Solar system passes through densest - and most dangerous, for collisions - part of our galaxy (Space, BBC1, 29/7/2001).

every 
450,000 yrs:
Average frequency at which pole reversals occur. Process of reversal can take between 1,000 and 10,000 years (Wikipedia).

every
413,000 yrs:
Period between maximum and minimum ellipticity of Earth Orbit (Milankovitch). 

every
100,000 yrs:
Stretch cycle as Earth’s orbit varies from the circular to the elliptical (DK World
Atlas, p .x), distance from the Sun varying between 92 and 95 million miles. N.b about every 110,000 years of the last 500,000 years of Earth history global temperatures have reached peaks/troughs. A further cycle whereby the Earth's orbit drifts up and down relative to the orbits of most of the other planets, esp. Jupiter (The Invariable Plane) takes around 100,000 years but the cycle relative to the Earth's present orbit is about 70,000 years. Cycles of Quaternary glaciation tend to conform to a 100,000 year cycle but changes in precession and obliquity are thought to be more significant (Wikipedia: Milankovitch cycles: the 100,000 year problem).

every
41,000 yrs:
Cycle of variation of the obliquity of the ecliptic, or angle of tilt of Earth (J.D.Hayes et al, in Hancock, p.79 and DK World Atlas). Currently it is 23.44 degrees from vertical in a cycle of 22.1 to 24.5 and back again (Milankovitch). This tilt is in the decreasing phase of its cycle and will reach its minimum value approximately by 10,000 AD (Common Era, CE).

every
25,800 yrs:
The Earth's 'wobble': cycle of precession of the Earth's axis, influenced by the gravitational pull of the larger planets, but controlled by the Moon (Frozen Earth, p.78). Thus Polaris will eventually cease to be the Pole Star (to be replaced by Vega) before returning to its present position after the above period of time.

every
23,000 yrs:
The Earth's orbit is elliptical, so during part of the year it is further away from the Sun than at the opposite time. Also the axis tilts by 23 and a half degrees (though this has not always been the case and the cause of it the subject of speculation; at the moment the angle is decreasing almost imperceptibly) so there is a twice yearly switch between perihelion (when the northern hemisphere is tilted towards and is at closest proximity to the sun) and aphelion (when it tilts away and is at its greatest distance), currently 4th January and early July. Therefore, present European winters would be a lot colder if these were reversed (Smith, p.188)......and summers hotter. Half way through this cycle the northern hemisphere, now tilting away from the sun, shall experience its shortest day on the solstice of June 21st.

5730 +/- 40 years: Half-life of Carbon 14, used to measure age of relatively recent remains up to about 150 years ago.

every
2160 yrs: Earth's axis shifts about one degree every 72 years, giving rise to a slow transition of the Sun's position at the beginning of the vernal (spring) equinox each year. Measured in the constellations of the ecliptic - the Zodiacal ones - which occupy 30 degrees each - this translates into a different one of the twelve every 72 x 30, i.e.  2160 years. There is some disagreement over the calculation as to when a sign is entered and left. For a substantial part of this Chronology the ages are those of Gemini, Cancer, Taurus, Aries and Pisces.

every
1500 yrs+/- 500 yrs: Solar-driven global climate cycle hypothesis developed by Dansgaard, Oeschger and Lorius. Awarded Tyler prize in 1996 for discovering regular pattern of warming/cooling. E.g. 900 AD-1300 AD =Medieval warming.

every 210 and 87 years: Solar cycles, related to the shorter sunspot cycle (Potsdam Institute for Climate Impact Research). In combination, these could produce a 1,470 cycle (see every 1500 years, above).

every
18.6 yrs:

Cycle of northerly and southerly monthly extremes of lunar declination. This is also the 223 month 'Saros' cycle after which the pattern of lunar eclipses repeats.

every
11 yrs:

Maximum/minimum Sunspot cycle.

750-
570m BP: Earth's oceans may all have frozen several times (Nature December 1998) - tipped inclination of the Earth to 66.5 degrees? (Smith, p.183).

650m BP: Drop stones in Namibia suggest “Snowball Earth”? Only life - cyanobacteria and blue-green algae. Then after 10 million yrs without rain, volcanoes increase atmospheric CO2 to 10%. Then storms; rapid thaw (Horizon, 22/2/01).

300m BP: Permo-Carboniferous Ice Age covering S. Pole in Gondwanaland - S. Africa, Australia, India (Earth’s Story, also MacDougall p.142) lasting 60 m. years. Coincides with all-time low CO2 levels.

290-
245m BP:
Permian period (DK UVE).

270m BP: Oldest surviving oceanic crust: the eastern Mediterranean, the remains of the Tethys Sea.

252m BP: Lava floods out of Siberian traps, resulting in a spike of carbon dioxide and other greenhouse gases into the atmosphere. Rapid global warming, and acidification of the seas ensued decades later as the atmospheric dust cleared.

251m BP: Permian-Triassic extinction. Earth's worst mass extinction, (until that recently initiated by mankind), but cause uncertain (Siegel). A site off Australia's NW coast where an object about six miles across may have smashed into the Earth at this time is a candidate for the cause (Singer and Avery p.77, taken from Washington Post 14th May, 2004). 84% of marine genera perished. The only known mass extinction of insects. http://news.bbc.co.uk/1/hi/sci/tech/1184556.stm.

214m BP: An asteroid about 3 miles across, crashed into Canada (Manicouagan crater). Produced, amongst other phenomena, layer of molten glass detected in Triassic rocks nr. Bristol (Science, 14 Nov. 2002).

214-
199m BP: End Triassic extinction, probably caused by lava erupting from the "central Atlantic magmatic province", an event that triggered the opening of the Atlantic Ocean and possibly global warming. 52% of marine genera perished (Siegel).

200m BP: Most of the Earth's oceanic crust is about this old, with the oldest surviving being the eastern Mediterranean, the remains of the Tethys Sea, at about 270 million years old. See 'expanding Earth' theory on the Internet!

145-
70m BP: Relatively high sea levels. Super-continent Pangea breaks up.

65.5m BP: Deccan Traps: over a a million cubic kilometres of lava poured out over central India.

65m BP: Asteroid c.7 miles diameter crashed into Yukatan Peninsula, coinciding with demise of dinosaurs at the end of the Cretaceous period. Sea levels “fell markedly”.

55m BP: Palaeocene-Eocene ‘thermal maximum’ - North Pole “Subtropical” (BBC News Online, 7/9/04). Lasted about 100,000 years. Large undersea methane release caused explosions and mass extinctions.

According to ice cores and fossilised algae, average temperature was 20 C instead of present -1.5 C. Glomar Challenger: Rockall Ridge becomes separated from Greenland and begins sinking (Sullivan, W. Continents In Motion, MacMillan, 1974). Further sinking 40 and 15 my BP. http://www.sciencedaily.com/releases/2001/12/011210163439.htm

African plate pushes into the European creating the Alps and other ranges (Science Daily 5/5/2009).

40m BP: Trend towards global cooling (In Our Time, Radio 4, 22/10/09).

35m BP: Wave of extinctions during Eocene-Oligocene transition; “sea levels again very low”; Antarctica moves over South Pole (CDE, pp.9 and 11). Evidence in Chesapeake Bay of a bolide (comet or meteorite) a few miles in diameter  having gouged out a crater, nearly as deep as the Grand Canyon on impact around this time (Schoch, p.182).

33m BP: First Antarctic glaciers (Wikipedia).

30m BP: ‘Rubble pile’ meteor fireball exploded above Egyptian Sahara melting the sandstone at 1800 degs C. Similar to Tunguska event? (‘Tutankhamun Fireball’ Horizon 20/7/06).

20m BP: (Early Miocene) 12.5 mile wide crater made in Canadian Arctic's Devon Island . Prior to this fauna and flora quite different, e.g.shrews, rabbits, rhinos, birch etc., indicating milder climate similar to Minnesota &and (Schoch).

9m BP: Continuous West Antarctic Ice sheet develops.

5.96m BP: Messinian Salinity Crisis, until 5.33m BP. During the Miocene epoch, Mediterranean cut off from the Atlantic leading to partial or complete evaporation.  Depth of evaporites indicates process must have been repeated several times.

5.8m BP: Oldest known human ancestor, Ardpithecus Ramidus Kaddaba, in Ethiopia (Species first discovered 1992).

5.33m BP: Re-inundation of Mediterranean basin though water did not match present level until 'great melt' about 12-10,000 BP. Black Sea remained cut off until at least 7,500 BP as suggested by mollusc fossils. Bosphorus overwhelmed about a thousand years later, reaching the same level as the Med.

5m BP: Panama isthmus forms - blocked ocean circulation, triggering Ice Age?

4.4m BP: Ardipithecus ramidus female, bipedal earliest human ancestor? Guardian, 1/10/09.

2.5m BP: Earth entered into most recent Ice Age (Encarta). Possibly still in it, with current interglacial. Between 2.5 and 0.9million years BP glacial-interglacial cycles occurred every 41.000 years; since 0.9 million years BP every 100,000 years due to changes in the Earth's orbit in respect of the Sun (Maslin, Global Warming p.12, Science Made Simple booklet, 2008). Earliest tools (of Homo rudolfensis) dated to around this time.

2.5m BP: Britain may still have been an island around this time (Pliocene Period) - Stringer.

2.1m BP-
400,000
        BP: According to the cover article in the Dec.18th 2003 issue of Nature, a tilt of Mars' rotational axis greater than today's produced and advanced ice sheet at both poles to around 30 degrees latitude in both hemispheres. This subsequently melted (leaving river beds and ice deposits?) as the planet entered the current inter-glacial epoch.

2m BP: Australopithecus sediba, an erect humanoid with tiny hands, opposable thumbs and a human-shaped brain case, whose remains were discovered in a South African cave, reported in Science 8th September 2011; the best candidate so far for a missing link between apes and Homo sapiens?

1.8m BP: Skull and other bones found in Georgia are the oldest Hominids (of our Genus, Homo) discovered outside of Africa. Dmanisi people: shorter and with brains 40% smaller than typified by Homo erectus. Suggests an earlier wave of migration out of Africa (according to orthodoxy 1m BP) which may have died out or returned to the mother continent. (Independent, 9/9/09.)

1.8m -
20,000 BP: Homo erectus.

1.8m -
10,000 BP: Pleistocene Period, when temperatures were probably 4-5 degrees C lower than at present (Wikipedia).

1.7m BP: Oldest hominid (not yet Homo sapiens) skulls found in Europe (Georgia) (Bryson, p.390).

1.3m BP: Super volcano eruption in Idaho, U.S.

1.1m -
900,000 BP: Pole reversal, lasting until 780,000 BP (see below). Average frequency: every 200,000 years (Magnetic Flip).

1m BP: Could humans have arrived in Britain nearly 1m yrs ago? Stone tools discovered in Happisburgh, Norfolk UK suggest this is possible (Nature/BBC News July 2010). Environmental data suggests cool temperatures. Most likely species Homo antecessor, dated to 0.8-1.2 m yrs ago in northern Spain.

900,000 BP: Range to which ice cores can yield information about climate variations (Singer and Avery, p.6). National Geographic article dated July 5th 2007 claims 800,000 BP through the 3,260 metre ice core taken from central Antarctica.

850,000 BP: Early humans of unknown species first reach Doggerland (present day North Sea), according to BBC Focus magazine, November 2012.

800,000 BP: ’Rubble pile’ believed to have ignited over huge area of SE Asia (Horizon, 20/7/06).

800,000 BP: "Earliest evidence of human footprints outside of Africa discovered in Norfolk" -Happisburgh.

780,000 BP: Last scientifically estimated major magnetic pole reversal, Brunhes Matuyama, (Magnetic Flip, op.cit, based on analysis of Hawaiian lava and metallic content of other sediments; also mentioned RI lecture 1995/6 BBC2). Hancock disagrees (see 12,500 BP) see also Wikipedia', 'Geomagnetic Reversals'.

740,000 BP: Massive volcanic eruption of Toba on Sumatra, collapsing into its own magma chamber. Forty times as severe as Tambora in 1815 (Whyte, p.79)

700,000 BP: Analysis of animal bones (butchery marks) at Westbury-sub-Mendip suggest hominid habitation 200,000 yrs earlier than Boxgrove Man. (Times, 4/6/02.)

640,000 BP: Last known major eruption of supervolcano underneath Yellowstone National Park (55 miles across) (BBC news website 11/12/13).

524,000-
478,000 BP: Dating of tibia of 'Boxgrove Man' (Homo heidelbergensis), an ancestor of H. sapiens and H. neanderthalensis.

500,000 BP: Scientists believe oldest and deepest ice formed in East Antarctica (Feuerbacher). 'Angian' stage of ice age affecting Britain, Thames diverted south. Also around this time, DNA divergence data indicates that the split between modern humans and Neanderthals took place.

430,000 BP: Termination V: Interglacials shortened and became warmer, allowing humans and other warm blooded creatures to thrive. Today's CO2 levels are the highest in 440,000 years ('Next Ice Age Is 15,000 Years Off", www.abc.net.au/science/news/stories 10/6/2004).

420,000 BP: A global temperature high, as measured by Vostok ice core, Antarctica (next: 330,000).

400,000 BP: Approximate age of Swanscombe (Kent) skull and associated hand axes. Hoxnian interglacial, towards the end of the Lower Paleolithic. English Channel not yet formed, but giant freshwater lake trapped south of North Sea ice periodically overflowed and flooded towards the south west (see 9,000 BC). Siberian stalactites/stalagmites record warming of around 1.5 degrees C; if global warming now was as great, trillions of tonnes of greenhouse gases would be released into the atmosphere with severe economic and environmental consequences (BBC website 22/2/2013).

400,000 BP: Neanderthals and Denisovans thought to have diverged, evolution-wise, from modern humans.

400,000 BP: End of most recent Martian ice age according to current thinking i, 26/4/2014).

300,000 BP: Highest CO2 level until present, as measured by ice cores.

200,000 BP: Gullies in youngish Martian crater indicate flow of water since this time (i, 26/4/2014).

180,000 BP: Britain joined to France by land bridge, as at 20,000 BP.

160,000 BP: Oldest Homo Sapiens skulls found in Eastern Ethiopia (BBC website news, 11/6/03).

150,000 BP: Studies of human genetic variation reveal everyone (Sapiens) on Earth descended from one woman who lived in Africa -coalescence of mitochondrial DNA (Olson, Mapping Human History p.27). All other lines eventually became extinct. Neanderthals in Jersey at this time, land-linked to France (Stringer, pp. 104-106), but apparently not in England.

150,000-
 60,000 BP: No trace of humans (Neanderthals) in Britain during this period, despite pleasant climate. (Stringer, pp 103-106).

140,000 BP: Global temperature/CO2 low, as measured by Vostok ice core (next: 20,000 BP).

135,000-
115,000 BP
: Eemian interglacial during which temperatures were on average 2 degrees higher than at present but there were big fluctuations in less than a couple of decades (Feuerbacher, p.5).

130,000 BP:Global temperature/CO2 high, as measured by Vostok ice core (prev. see 240,000 BP). It was 4.5 degrees C warmer than today. Around this time Homo sapiens appeared.

130,000-
110,000 BP: Eemian Interglacial, warm period. 

127,000 BP: Termination of first recent Ice Age (Feuerbacher). Oceans slower to warm than land.

125,000 BP: Sea level fell, exposing raised beach in Barbados (Earth’s Story). Very warm period. Edinburgh Uni team (see also 82,000  and 40,000 BP) .

125,000-
90,000 BP: Greening of the Sahara with lower sea levels may have allowed humans to migrate out of Africa successfully for the first time via the strait across the Persian Gulf to Aden (BBC 2 10/5/09). Genetics traces all present day races to this group.

120,000 BP: Climate in UK warmer than today - by about one degree Celsius. Hippos in Britain (excavated from foundations of buildings on Trafalgar Square - Stringer, p.110). Ice Ages followed. (Hot and Cold Night, BBC2, 30/8/99.) Camp Century core shows Ice Age begins in Greenland. Then see 75,000 BP. First ceremonial burials

115,000 BP: Start of last Ice Age (Fuerbacher). Atlantic Ocean conveyor reversed

110,000 BP: "Sudden" (over less than 400 yrs?) shift to colder climate globally. Desertification as moisture taken out of water cycle and frozen in growing ice caps/glaciers. Forests to grass, etc. (Singer and Avory p.xiv).

100,000-
60,000 BP:
Believed ‘modern’ humans settled in Asia (from Africa), eventually displacing Homo erectus.

93,600 BP: Speculative earth crust displacement (Flem-Aths, after Hapgood) Next see 52,600 BP, below.

93,000 BP: N. Pole, centred on Yukon, moves to Spitzbergen (Hapgood).

90,000 BP: Warmth-loving species such as Hippos, Hyaenas and Lions replaced gradually by Mammoths, Wolves, Bison etc, but tropical species gone altogether by 15,000 BP.

82,000 BP: Sea level fell again exposing raised beach on Barbados once more? (Earth’s Story).

80,000 BP: N. Pole leaves Yukon 63N 135W (Hapgood), 5,000 years later arriving over the Greenland Sea. Approx. date of contents of Banwell bone cave, N. Somerset: Arctic Fox, Wolverine, Arctic Hare but no evidence of humans. Remains of beetles in London and Oxford suggest warmer further East?

80,000-
60,000 BP: Window of opportunity in which humans could reach down through SE Asia to Borneo "without getting wet" according to Oppenheim. Optimum: 65,000 BP - when the distance between Timor and Australia was a mere 153 km with lower sea levels (IHJ:Aus).

75,000 BP: N. Pole reaches the Greenland Sea 72N 10E from The Yukon (Hapgood, on www.poleshift.org/ps/PolePaths.html). Camp Century core on Greenland records major ice advance (Fuerbacher, p.3).

73,000 BP: Supervolcano Toba eruption in Indonesia, deforests and leaves ash as far away as India. Reduces human population on Earth to around 10,000 individuals. Greenland ice cores indicate that an 'ice age' was triggered, lasting for around 1,800 years (Science Daily, 23/11/2009).

70,000 BP: European Ice Age begins ? Movement of Homo Sapiens out of Africa. DNA analysis of an aboriginal human hair, donated in 1923, shows that Australia's indigenous population were first isolated around this time. This is now believed to be the first wave of African emigration (American Journal Of Human Genetics, week beginning 18th September 2011). With sea levels lower than today they would have been able to cross through Indonesia relatively easily. Possibly arrived in Australia around 50K BP. See also 38 K-25 BP.

60,000-

60,000-
40,000 BP: Human entry into Australia, predating that into Europe? Extinction, (through hunting ?) of giant Kangaroo circumstantial. Use of ochre as a pigment to 'paint' (IHJ). MacDougall places human entry into Australia at 65,000 BP and New Guinea 45,000 BP (p.204).


60,000-
23,000 BP:
Bones of Cro-Magnon man found on dried out lake Mungo, NSW, Australia (Bryson, pp. 402-3). Australia previously thought inhabited the last 8,000 years.

55,000-
50,000 BP: N. Pole leaves Greenland Sea, moves to Hudson Bay 60N 73W (Hapgood). England warmest.

52,600 BP: Speculative earth crust displacement (Flem-Aths, after Hapgood), bringing Canada to North Pole. Next see 9,600 BC, below.

50,000 BP: Small (30 yds across) asteroid hit Arizona, blasting half mile crater.

50,000 BP: Brazil: Bones, hearths, charcoal suggest indigenous population before invasion of Americas by Mongoloids (Ancient Voices, BBC2, 1/9/99). Remains resemble Negroid Australian aborigines.

45,000 BP: Oldest radiocarbon dates now known for Adélie penguins: sites occupied by Adélie penguins prior to the last advance of the Ross Ice Sheet at the end of the Pleistocene documented, indicating that open water conditions must have existed in the Ross Sea at that time. In addition, radiocarbon data reveal penguin colonies today are no older than 1000-2000 years old so there were periods in-between when no pebbles were available for nesting (Emslie, Stephen D. 45,000 Year Old Record of Adelie Penguins And Climate Change In The Ross Sea, Antarctica, Geological Society Of America 2nd January 2007). These penguins nest on ice-free coastal areas.

45,000 BP: New evidence suggests Homo sapiens had reached Europe earlier than previously thought, and co-existed with Neanderthals for around 5,000 years (Nature, August 2014).

44,000-
41,000 BP: Teeth and a piece of jaw found in Italy and Kent's Cavern, Torquay indicate earliest Homo sapiens presence in Europe (Nature, November 2011).

41,000 BP: Brief complete pole reversal, Laschamp Event, with the change in polarity lasting about 250 years (Wikipedia).

40,000 BP: Linguist estimates Andaman islands became isolated in Indian Ocean (C4 In Search of Eden, 14/5/01). These tribes carry Asian as well as African marker in DNA.

40,000 BP: Very cold period, acc. to Edinburgh Uni team’s study of corals (Times, 26/1/01), also Fuerbacher. Neanderthals hit hard. Oldest human (Cro-Magnon) skull in Europe found in Cave Of Bones, Rumania. Bosphorus did not exist; humans migrated into Europe via the Danube? Many Europeans' DNA traceable to this time. Now see also 44,0000 BP.... busy period this, with humans reaching Siberia (stone tools and reindeer bone needles) from south west, following prey?

40,000-
35,000 BP: First hunter-gatherers moved into Palaeolithic southern Europe from the Middle East. (Sykes, B. Daily Mail 11/11/00); earliest footprints in the Americas? dating of footprints in volcanic ash in Mexico suggest peoples arrived by sea (BBC website 5/7/05). Previously thought to be 12,500 BP via Siberian land bridge.

39,300 BP: Campanian Ignimbrite eruption - reduced temperatures in what was already a cold period by a couple of degrees or more - Middle to Upper European Palaeolithic Transition.  Major eruption of Campi Flegrei (Phlegraean Fields) near Naples (Napoli) in Italy. Caused late Pleistocene biocultural changes and is indicated in Greenland ice core samples. Possibly related to the demise of the Neanderthals, though no trace found so far of any after 40,000 BP.

38,000-
25,000 BP: Split in the second major wave of migrations from Africa, with the ancestors of the Han Chinese going East mostly through central Asia, the European antecedents North via the Caucasus and Turkey (American Journal Of Human Genetics, week beginning 18th September 2011).

37,000-
23,000 BP: Isle of Lewis, Scotland found to be unglaciated (Nature 309, 1984, 701-3).

35,000 BP: Start of recent Ice Ages, acc. to Earth’s Story, 13/12/98. Around this time the path from Asia to the Americas may have been open allowing humans to settle the New World in advance of the Clovis migration; genetic 'evidence' compatible (Mapping Human History p.205.) 

33,400 BP: Last date obtained for Neanderthals.

33,000 BP: Paleolithic 'mine' found in Egypt (Schoch, p.56). No stalagmite growth around this time, indicating a cold period (whereas there was growth circa 35,000+ BP).

30,000 BP: Worlds oldest known cave paintings at Chauvet (Focus 6/96 p.83). Sabre tooth tigers still in Britain (Time Team, C4, 'Britain's Drowned World 24 Apr 2007). Humans reached edge of Arctic Ocean. Peak of Ice Age 5,000 years later forced humans south to Mongolia. (IHJ:Asia.) Coldest point of Ice Age? (Singer and Avery). Extensive deserts and semi-deserts; sea level about 400 feet lower than today.

30,000-
10,000 BP: Upper Palaeolithic (Old Stone Age); followed by Mesolithic.

29,500-
15,000 BP: Glacial marine ice cores, Ross Sea.

25,000-
20,000 BP: Second wave of people moved into southern Europe from Middle East. 'Peak of the Ice Age' (IHJ:Eur).

24,000 BP: Disruption to the Gulf Stream, exacerbating effects of Ice Age (Iceworld, Channel 4, September 2002). N.B. Stream can boost European temperatures by 15 degrees C. U.K. Uninhabitable under half a mile thickness of ice.


22,000 BP: Traditionally when man entered New World from Siberia (TAWH p46). But see also 50,000 and 35,000 BP. At this time, characteristic tool cultures are the last indication of Neanderthal presence - at Gibraltar (Wikipedia).


20,000 BP: Global temperature/CO2 low, as measured by Vostock ice core (prev. 140,000 BP). This is the lowest temperature - 10 degrees Celsius lower than today - recorded in the last 800,000 years according to Jean Jouzel in Science July 5th 2007 (the warmest was 130,000 years ago during the last interglacial - 4.5 degrees C warmer than today).

20,000 BP: White’s guestimate for birthdate of Adam (How Old is the Earth? p.29). Britain may have been joined to France, indicating lower sea levels around this time. Human footprints around Lake Mungo, S.E. Australia dated by luminescence in sand grains (IHJ:Aus). See also 60,000 - 40,000 BP.

18,000 BP: Sea levels begin to rise significantly.

18,000 BP: Skeleton of 3’ high Homo floresiensis, discovered October 2004. Did this branch of humanity survive another 6,000 years? (S. Times 31/10/04). Salutrian civilisation in France/Spain. Technology bears similarities to Clovis 5,000 years later. Has led to theory that these Europeans crossed Atlantic to Americas via skin boats and ice floes. Pre-Columbian. DNA evidence seems to support this mixing.

17,000 BP: East Antarctic Ice Sheet retreats. North Pole leaves Hudson Bay, to arrive at its present position 12,000 BP (Hapgood). N.B. in Hapgood’s “revised version” the movement is not immediate (http://www.poleshift.org/); his theory is criticised by Schoch. Posnansky's est. of the date of the Kalasasaya at Tiahuanaco based on obliquity of the ecliptic (Hancock pp. 76-); end of the last ice age (Furlong); possible era of the migration of Negroid peoples into S. America? Hancock cites Irwin, C. Fair Gods and Stone Faces, 1964.

Lascaux cave paintings, France depict animals (bulls, horses etc) which would not have been found in the region during the Ice Age - Frank Edge's summer sky map of 15,000 BC theory with Taurus
and other constellations depicted to fix the summer solstice (Schoch, p.65). Over 17,000 years recorded by cave stalagmites in Sauerland, Germany trace periods of warming and cooling of the Earth (Niggemann et al., A Paleoclimate Record of the Last 17,600 years in Stalagmites from the B7 Cave, Sauerland, Quaternary Science Reviews 22 (2003) pp 555-67.

Also at this time there may have been a major volcanic eruption in Indonesia causing the demise of Homo floresiensis.

17,000-
14,000 BP: First inundation of Black Sea with Mediterranean saline overspill? (BBC Focus magazine, November 2010.), See also 5,500 BC.

16,000 BP: Global warming (Olson, p.99).

15,500 BP: At Buttermilk Creek, Texas, archaeologists have found up to 19,000 stone tools. The site "has yielded more pre-Clovis tools than all other such sites combined" (Scientific American, November 2011). It is thought that these peoples entered the Americas by crossing a dry Beringia (sea levels being much lower during the Ice Age), "leaving their East Asian homeland sometime between 25,000 and 15,000 ears ago".


15,000 BP: Pre-Clovis peoples in America? Occupational layer more than 15,000 years old near Richmond, Virginia (Mapping Human History, p.199).

14,000 BP: Generally accepted approx. end of last Ice Age, with ice caps retreating in both northern and southern hemispheres. Earth temperatures rose to approx. those of today. Sea levels rise, forests spread (Singer and Avory).  North Atlantic ‘conveyor’ resumes (Feuerbacher, p.9). First of the floods caused by catastrophic melting of the ice caps Oppenheim, p.24). Start of the Holocene epoch. The pole star was Vega at this time, 12,000 BC.

End of Pleistocene - accompanied by extinction of two thirds of large mammal species in North America. Palaeolithic hunters or rapid climate change?

Bones discovered in Shropshire in 1986 provide evidence that Woolly Mammoths had returned to Britain after the severest period of the Ice Age - migrated from the south? Most likely cause of their eventual demise thought to be reforestation of their preferred grassland habitat. (BBC News, 18/6/09.)

13,000 BP: Clovis (spear) technology in Mexico marks leap forward. Oxygen isotope records from Greenland suggest climate warm but starting to get colder again - within 700 years an ice cap had built up in Scotland (Earth Story p.166, Whyte p.2). This period known as the Younger Dryas stadial, lasting for about 1500 years. Temperature drops by about 15 degrees Celsius in Britain and Greenland within 10 years.

13,000 BP: Human remains on California's Channel Islands dated to. Evidence challenges orthodox theory of migration into the Americas which requires peoples to cross the Bering Strait into central Canada and then southwards.

12,900 BP: Clovis peoples and the giant animals of their time vanish. New evidence suggests...."a comet, possibly 1.9 miles wide, smashed into the Earth's atmosphere" setting much of North America ablaze..evidence from "a thin layer of strange debris featuring microscopic diamond dust and...iridium...peppered across North Africa and parts of Europe. Fireballs ...crashed into much of the vast icesheet covering the northern half of North America...exactly when colossal meltwaters surged into the North Atlantic, throwing ocean currents off course and plunging the world into an abrupt freeze that lasted more than 1,000 years" (Times, 29/5/07). Carl Munck claims this is around when Atlantis was destroyed.

Laacher See volcanic eruption in Germany also around this time.

12,800-
12,600 BP: Best estimate of the beginning of the Younger Dryas, a cold spell affecting mainly the Northern Hemisphere (though MacDougall on p.198 admits the event "was a global phenomenon"). Droughts prevalent in north, affecting Mammoths? (Whyte). Equals 10,800 BC, easing off about 11,600 BP (9,600 BC); the cooling less rapid and more intermittent than the warming at the end of the period. Around this time North American Lake Agassiz emptied huge volumes of fresh water into the St Lawrence Seaway - causing the Atlantic Conveyor to weaken/stop? (MacDougall, pp 109-110.) See also 6,200 BC (8,200 years ago)...

12,500 BC-
10,000 BC: Age of Leo in astrological terms.

12,500 BP: Hancock, Bauval assert is the Egyptian 'First Time', also date of last geomagnetic reversal (p.484). Cite Nature and New Scientist 6/1/1972 p.7. Monte Verde, Chile site discovered in the 1990s suggests South America peopled before Clovis' ancestors entered from Asia (Schoch, p.60). Climatically the Younger Dryas starts here - Earth plunged back into fresh but short-lived Ice Age after initial recovery 1500 years earlier.

12,350 BP: Morner and Lanser (1974) postulated a magnetic pole excursion from a core taken from the Gothenburg Botanical Gardens in Sweden, hence 'Gothenburg Flip'. However other scientists have failed to validate this finding.

12,300 BP: Arabs dated The Flood. Hancock Keepers of Genesis, p242. Before 10,000 BC, global sea levels are said to have been  90' to 100' lower than the present day.

12,178 BP: Celestial pole inclined 30 deg. from present position (Allan and Delair, p15, taken from Noel, M. and Tarling, D.H. Laschamp Geomagnetic Event. Nature vol.253 pp 705-6, 1975).

12,000 BP-
10,000 BC: Around this time the global human population estimated to be around a million (Whyte, p.50. Most of the large Mammoths became extinct over this period. Small ones survived on Wrangel Island until around 1700 BC.

12,000 BP = 10,000 BC. This chronology uses 'BP' prior to this date - HGS.

10,000 BC:  Pleistocene-Holocene transition. Second pulse of post glacial flooding (Hancock, Flooded..., op.cit) as temperature rises. CO2 in the atmosphere reaches its lowest level (Feuerbacher, p.4). 7 degree temperature rise in 15 years (Time Team, C4, 'Britain's Drowned World', 24 Apr 2007).

10,000-
 4,000 BC: Mesolithic hunter-gatherers in Britain.

9,600 BC: Traditional date for destruction of Atlantis (Solon). Speculative date of earth crust displacement (Flem-Aths, after Hapgood), based on sudden mass extinction’s. North Pole moves to present location - contradicts Hapgood's 12,000 BP. Tollmann's estimated date of Great Flood, ending most recent Ice Age (prevalence of tektites, sudden increase on Carbon 14 in fossilised trees, caused by impact explosion?). (Schoch, p.199; original source not given in his bibliography.)

9,600 BC: Sudden warming of climate shown by Greenland ice cores which record a 14 degree jump in 15 years (Schoch, p.172). Thus the Younger Dryas gave way to the Pre-Boreal, and finally the Boreal (9,000-7500 BC). Did poles shift?

9,500 BC: Speculative Phaeton catastrophe (Allan & Delair). Also time of the disintegration of comet precipitating Ice Ages according to Clube and Napier; much dust deposited 10,000 yrs prior to this (CDE, p.10 see also Schoch, p.205). Second of the great floods caused by catastrophic melting of the ice caps Oppenheim, p.24). Approx. date of destruction of Atlantis (Hancock, Flooded Kingdoms of the Ice Age, Ch.4, 11/2/02).

9,500-
7,000 BC: Early Holocene climactic optimum confirmed by Antarctic ice cores. Was this the last time the Atlantic Conveyor closed down or retreated south? (Stringer, p.149.)

9,500 BC-
date:  Considered an interglacial period. Planet warms to present temperatures in about 100 years. Ice sheets melted, sea levels rose, forests expanded at expense of grass and deserts shrank (Singer and Avery.)

9,200-
8,000 BC: 'Amazon cave findings shed new light on American prehistory' (Times, 19/4/96): evidence of the peopling of the Amazon basin independent of Clovis.

9,000 BC: Northern Europe and north-eastern North America reverted to glacial conditions in less than 100 years; the Younger Dryas. Caused by massive amounts of meltwater exiting the St Lawrence Seaway? (Feuerbacher, p.10).

Rising sea levels create permanent English Channel (preceded by a 'super river' which drained the southern North Sea to varying degrees after approx 450,000 years BP - Independent, 30th November 2009).

Female Negroid skull discovered 1999 in Serra Da Capivara, NE Brazil. Cave paintings suggesting possible scenes of violence with Mongoloid peoples? Oldest (non-Mongoloid) skull in Tierra Del Fuego (Ancient Voices, BBC2, 1/9/99). ‘Japanese’ Jomon pottery - the oldest in the world (Oppenheim).

9,000-
1 BC: Period during which Antarctica may have been mapped as an unglaciated archipelago by Buache, the C18th French geographer (Hapgood; Hancock). For a refutation of this theory see http://xoomer.alice.it/dicuoghi/Piri_Reis/PiriReis_eng.htm

8,500 BC: Approximate age of the Earth according to modern day creationists, based on the alleged imbalance of Carbon 14 in the atmosphere (White, p.88). Approximate date of Noah's Flood according to other creationists who base their surmise on the archaeology mentioned in Genesis compared with the dating of the Bronze Age, etc. N.b. the half life of Carbon 14 is 5730 years; however it can be traced in Carboniferous geology.

8,000-
4,800 BC: Britain exposed to "monsoon" (hot and moist) type climate (Langdon, p.54). Contains the so-called 'Atlantic Period', as determined by the pollen counts of trees thriving in this period. However, cold snaps between 7,200-7,200 and 6,600-6,500 BC, etc. (+see below).

8,000-
3,000 BC: Strong 'seasonal' (=monsoon?) rains in Sahara, as evidenced by alternate layers of sand and clay in rocky outcrops in Egyptian Desert. One 'lake' bigger than the UK.N.b even hotter Saharan temperatures than at present required to create the extremes of air temperature to precipitate (literally!) a monsoon.

Cave paintings dated to 8000 BP (6000 BC) show 'athletic' humans, variety of Savannah mammals and maybe even human swimmers (Orbit, BBC 2, March 2012). The programme thought a cyclical maximum in the tilt of the Earth's axis, to about 24.5 degrees (whereas at present it is 23.4 degrees), was the cause.

7,911- 
7090 BC: Several great volcanic eruptions (Feuerbacher).

7,800 BC: Warren Field, Aberdeenshire pit alignment dated to and in use for about 4,000 years thereafter according to excavation (Current Archaeology 283, October 2013 pp 12-19). Speculation it could have been a lunar calendar, far earlier than was previously thought possible.

7,000 BC: It was around this time, according to Prof. Colin Renfrew's late 1980s Anatolian hypothesis, that Indo-European languages originated in Anatatolia (Modern day Turkey). This has been supported by New Zealand researchers (Nature, August 2012) using phylogenetic methods from evolutionary biology. The findings contradict the rival Steppes/Kurgen theory which holds that proto-Indo-European developed in and spread from north of the Caspian Sea in the Russian Steppes around 5,000 years B.P. (Indo-European includes the Germanic languages which also led to English.

6,600-
6,500 BC: Very cold snap in Britain prior to the generally warm Atlantic Period?

6,500 BC: Core sample suggests The Solent first inundated by the sea - remains of a flooded oak forest. More and more land disappears in the following centuries as isostatic re-adjustment takes place following the last Ice Age. Flint tools found from just after this period.

6,100 BC: Tsunami originating from the coast of Norway destroys what remains of Mesolithic Doggerland, cutting Britain off from Europe (BBC Focus November 2012 p.37). As explored later on The Stone Age Tsunami (Channel 4, 30/5/2013) this was caused by the earthquake-triggered Storegga Slide. The evidence includes a thin sandy layer with the microscopic remains of smashed diatoms found between the clays along points of the Scottish (e.g. at Montrose) and Northumberland coasts. This water would have receded unlike the flooding caused by the final release of Lake Agassiz around 4,200 BC, but is believed to have been finally abandoned around 6,000 BC.

Ex.13:21 "pillar of cloud/fire" -volcanic dust? A.A. states this was the second largest eruption of all time, after Tambora, Indonesia, 1815. BBC2 Timewatch programme of 20/4/07 propounds tsunami theory for the ultimate destruction of Minoan power as Crete is bombarded with waves after Santorini eruption.
