Human Origins and Glacial Interglacial Cycles

© Lori Lappin, the Witch of WITCHCRAFTS ARTISAN ALCHEMY®


As shared in an earlier post, I believe current scientific and genetic data strongly support that archaic Homo sapiens first evolved in Eurasia (bottom red enclosed area, map above), then one population split off and migrated into Africa (brown line). The remaining genetic cluster migrated west and north (as the Himalayan Mountains blocked any migration northeast into Asia).

My hypothesis also has some interesting support in Biblical folklore, inasmuch as I believe the Bible to be a record of folk memory interspersed with a deliberately inserted theocratic political agenda of an ancient ruling class. Biblical folk mythology records that Homo sapiens (the first humans, Adam and Eve) were formed (a new species of humans emerged) in a Garden of Eden. This garden where our species was born is believed by those of the Abrahamic faiths to have been located in Iranian Azerbaijan. Interestingly, Iranian Azerbaijan is exactly on the dark purple line where I have proposed that the Europid/Mongolid/Siberian-Amerindian genetic cluster left the original Homo sapien homeland (located within the bottom red circle within which greater Iran is located and where Homo sapiens emerged as a species distinct from other archaic hominins according to my "Out of Antarctica" theory of prehuman-human lineage origins). Likewise, within the context of my theory, the three "sons of Noah" in Biblical folklore code for the three major Homo sapien subspecies which emerged from around the area in which is located Mount Ararat (pink star on map), namely, the Europids, the Mongolids and the Siberian-Amerindians (as opposed to the common belief that the three sons of Noah represented the ancestral genetic fathers of the Europid, Mongolid and Negrid genetic clusters.

During the Pleistocene, glacial-interglacial periods have occurred regularly. Glacial ice sheet advances occur at intervals of approximately 40,000 to 100,000 years. These glacial-interglacial cycles also coincide with orbital changes of the earth which also dramatically affect volcanism, earth crustal displacement and upheavels, and other powerful natural phenomena. During interglacial periods, sea levels rise and many coastal and low lying areas around the globe flood. It is not far-fetched to think that the Biblical flood is a folk memory of flooding in areas around the Black and Caspian Seas. Mount Ararat is located near the eastern edge of the Black Sea, on the migratory route of non-African Homo sapiens out the land of our birth, where our species first emerged.

We know that the last glacial period (known as the Würm glaciation) can be dated to the time about 115,000 to 11,700 years ago, We are currently living in an interglacial period (since about 11,700 years ago). Prior to the Würm glacial period, the previous interglacial period known as the Riss-Würm interglacial period reigned upon the earth, beginning around 130,000 years ago and ending around 115,000 years ago. This glacial-interglacial cycle, where during the interglacial period there would be massive melting of ice sheets, volcanism, earth crust displacements and flooding, fits nicely with the timeline of the emergence of Homo sapiens around 200,000 years ago, followed by the first genetic split (which may have occurred around 150,000-130,00 as the previous Riss glaciation peaked and may have been a major impetus for the first migration of a population of Homo sapiens out of Eurasia and into Africa). The Riss-Würm interglacial period (spanning 130,000 to 115,000 years ago) may have been the driving impetus moving the Homo sapiens who had remained in Eurasia during the Riss glaciation to finally begin to migrate north, which was now warmer than it had been during the Würm glacial period. During this northward migration of this population of Homo sapiens, differentiation into the three major non-African genetic clusters began to emerge. These three emergent genetic clusters bloomed into beautifully differentiating genetic clusters as they migrated further north, between 115,000 to 50,000 years ago, finally taking different paths through Eurasia.

Taking all of this together, my "Out of Antarctica" theory of pre-human to human origins fits my own genetic data, what is known scientifically about population genetic clusters, the Chinese "Out of Asia" theory of human origins, and folk memory (as partially transmitted in Biblical mythology).
