Applying knowledge about DNA to the origins of human ancestry has produced some very interesting results which have led researching scientists to revise previous theories of the origins of modern man and the various ethnic groups of humans--not least the origins of the Native Americans.
While there are sufficient common DNA markers in today's populations to indicate that there have been various migrations from Asia to the Americas since 15,000 years ago, there are also DNA markers that are unique to American Natives that diverged as early as 30,000 years ago. This is substantiated in the Science Daily extract below.
This DNA data indicates that the common ancestors of Asians and Americans separated far earlier than 15,000 years ago, and this is in accord with the account given in Oahspe, where we find that the small groups of surviving I'hins from the continent of Pan landed in the five divisions of the earth around 25,000 years ago and mixed with the indigenous races to form the I'huans (a Proto Modern Man) some 24,000 years ago.
As is evidence from the conclusions in the Science Daily extract below, the
Bering land connection remains the pet theory for the inhabitation of the
Americas by the first humans, among academia to this day. But the lag of 15,000
years has scientists scrambling to reconcile new genetic information (which indicates
the first americans split from other groups of humans long before 15,000 years
ago) hypothesizing a period of 15,000 years where the ancestors of the American
Natives lived isolated from Asians somewhere around the Bering Land Bridge
before populating the Americas via the Bering land connection about 15,000
years ago. (See extract below)
Of course, one may ask: Why would a migrating hunter/gatherer population stay in a small area of extremely cool temperature for 15,000 years, when the way was open to go further, and how could they find enough food without ranging far and wide enough to find game and seasonal plants --- hypothetically, there were no obstacles, including territorial hostiles, to hold them back?
The simple answer is because the first modern humans appeared in the Americas not by the Bering land connection, but by sea, landing closer to the middle of the two land masses as shown in the map below.
According to Oahspe, the ancestors of the modern American natives landed on the west coast of Central America, around Guatemala around 25,000 years ago. From there they spread North and South, into both North America and South America. This central location would account for what otherwise appears to be an unbelievably rapid colonization across the vast distance of the two large continents of America, had the entry point of colonization actually been in the extreme north, at the Bering land connection.
Oahspe: The Lords' First Bk, 11/1.44-48.
|| And the Lord said: I numbered those who were saved, and there were twelve thousand four hundred and twenty; and these were all that remained of the first race of man that walked on two feet.
Behold, I will carry them to all the divisions of the earth, and people it anew with the seed of my chosen.
And Jehovih blew His breath upon the ships of His sons and daughters; blew them about upon the ocean; blew them to the east and west and north and south.
By the will of God, the ships were congregated into four fleets; thirty four ships into each fleet, except two ships, which were carried together in a fleet by themselves.
The Lord said: I will name the fleets of my chosen, and their names shall be everlasting on the earth. And the Lord named them Guatama, Shem, Jaffeth, Ham and Yista. ||
|| Questions about human migration from Asia to the Americas have perplexed anthropologists for decades, but as scenarios about the peopling of the New World come and go, the big questions have remained...... A team of 21 researchers, led by Ripan Malhi, a geneticist in the department of anthropology at the University of Illinois, has a new set of ideas........
"Our phylogeographic analysis of a new mitochondrial genome dataset allows us to draw several conclusions," the authors wrote.
"First, before spreading across the Americas, the ancestral population paused in Beringia long enough for specific mutations to accumulate that separate the New World founder lineages from their Asian sister-clades." (A clade is a group of mitochondrial DNAs (mtDNAs) that share a recent common ancestor, Malhi said. Sister-clades would include two groups of mtDNAs that each share a recent common ancestor and the common ancestor for each clade is closely related.)
Or, to express this first conclusion another way, the ancestors of Native Americans who first left Siberia for greener pastures perhaps as much as 30,000 years ago, came to a standstill on Beringia--a landmass that existed during the last glacial maximum that extended from Northeastern Siberia to Western Alaska, including the Bering land bridge, and they were isolated there long enough, as much as 15,000 years, to maturate and differentiate themselves genetically from their Asian sisters.
"Second, founding haplotypes or lineages are uniformly distributed across North and South America instead of exhibiting a nested structure from north to south. Thus, after the Beringian standstill, the initial North to South migration was likely a swift pioneering process, not a gradual diffusion."........
The team identified three new sub-clades that incorporate nearly all of Native American haplogroup C mtDNAs, all of them widely distributed in the New World, but absent in Asia; and they defined two additional founder groups, "which differ by several mutations from the Asian-derived ancestral clades."
What puzzled them originally was
the disconnect between recent archaeological datings. New evidence places Homo
sapiens at the Yana Rhinoceros Horn Site in Siberia, as likely a departure
point for the migrants as any in the region, as early as 30,000 years before
the present, but the earliest archaeological site at the southern end of South
America is dated to only 15,000 years ago........||
