The Peopling of the Prehistoric Americas (1,000,000 BC- 8,001 BC) Table of Contents

Approximately 998,000 BC: MAJOR CATASTROPHE: Ten percent of the island of Oahu Hawaii suddenly plunges into the ocean during an earthquake, creating a gigantic tidal wave for much of the Pacific Rim

Approximately 878,000 BC to 798,000 BC: Some factions of humanity may be managing to successfully traverse the oceans now, at least in part due to the organizational power of rudimentary speech skills

Approximately 400,000 BC: The Earth warms up considerably and stays that way for at least 30,000 years; Titanus may be going extinct in the Americas

Approximately 250,000 BC: Small but significant numbers of human beings may be reaching Valsequillo Mexico from across the Pacific now

Approximately 200,000+ BC: Humans are treating animal skins for use as clothing; people may be living in California

Approximately 128,000 BC - 108,000 BC: The Earth enjoys a warm but stormy interglacial span (the Eemian period) and the Bering land bridge is submerged

MAJOR ENVIRONMENTAL FACTOR: 118,000 BC to 8,000 BC: the last Ice Age; a third of Earth's surface is sheathed in ice for much of this period-- and world geography undergoes drastic changes

100,000 BC - 10,000 BC: Immensely large and terrifying predators stalk the wilds of the Americas...

Approximately 80,500 BC- 38,000 BC: The Bering land bridge connecting Asia to North America (Beringia) may be above sea level now

48,000 BC: Human population numbers begin to expand now beyond a long-time plateau

48,000 BC-38,000 BC; The fauna of western North America include terrifyingly fast and huge bears...

Approximately 43,000 BC- 30,000 BC: People are apparently living in some rock shelters in the region someday to be called Brazil

Approximately 40,000 BC - 36,000 BC: Australians reach the Americas

38,000 BC - 23,000 BC: The Bolivian altiplano plateau in South America is a high altitude (12,000 feet) inland sea during this time

33,000 BC - 30,000 BC: The extremely dangerous large predators of North America are encouraging some pioneers of the region to become specialists in maritime matters and living at sea

Approximately 31,000 BC- 8,000 BC: The Bering land bridge may be dry

31,000 BC - 12,000 BC: Substantial fluctuations in global climate afflict humanity and other lifeforms

31,000 BC: Humans are apparently living in the vicinity of Monte Verde, Chile

28,000 BC -8,000 BC: The great North American ice sheets come and go-- repeatedly

Approximately 28,000 BC- 23,000 BC: Four different groups of Asians enter the Americas (probably across the Beringia land bridge)

23,500+ BC-8,500 BC: There's a wealth of food suitable for human consumption in the form of animal life in the area of the northwestern Yukon (Alaska/Canada)....

Approximately 31,000 BC- 8,000 BC: The near unrecognizable shape of world continents during this period is due to reduced sea levels greatly expanding the areas of dry land

23,000 BC: Global sea levels of this time are at their lowest point for many millennia both past and future-- making this the most opportune time for many extraordinary migrations of human beings between continents; Clothing, baskets, cords, and hunting nets are being made and used in Europe

22,000 BC: Humans may be fashioning tools of bone in the northern Yukon

20,000 BC: Temperatures in the northern hemisphere are quite frigid

18,000 BC- 12,500 BC: People are apparently living in the vicinity one day to be known as South Carolina USA

Approximately 18,000 BC- 12,000 BC: Earth is bombarded five times by heavier than usual cosmic dust concentrations from space

15,000 BC to 3,000 BC: The great global erasure of much evidence of ancient human civilizations: World sea levels rise at least 325 feet over 12,000 years, erasing virtually all traces of 30,000+ years worth of possible civilizations and technology use

Approximately 13,000 BC: The very last of the giant 'terror bird' Titanus may be dying in Texas; up to now the vast majority of incursions into North America via the vicinity of the Bering land bridge have proceeded along the coast (as ice rules the inland routes)

Approximately 13,000 BC- 12,000 BC: Mass migrations into the North American heartland are becoming possible now as the ice retreats

11,000 BC: Many large animals of both North and South America are suddenly driven to extinction by the wave of Asians pouring out of the northwestern Yukon, as well as other peoples...

11,000 BC- 9,000 BC: Native Americans are definitely plying the seas by now, if not before

Approximately 10,500 BC: A sudden 20+ degree F rise in temperatures worldwide is causing substantial climate change

Approximately 10,000 BC: Total human population of the Americas may number around 10,000-30,000; virtually every human settlement in the world, both temporary and permanent, includes the presence of domesticated dogs

Approximately 9,000 BC: The Bering land bridge has not yet submerged. Is there trans-Atlantic trade (possibly secretive and/or rare) involving cocaine and tobacco taking place between Africa and South America now? Is it only a coincidence that Plato will later speak of Atlantis existing prior to this time?

Approximately 9,000 BC - 3,500 BC: "Exchange of goods" is begun...and a three dimensional combination of an accounting/inventory system and medium of exchange may represent the earliest pseudo-writing technology

Approximately 8,500 BC - 7,500 BC: The Bering land bridge slips under the sea again, separating the Americas from Asia
