Stephen Oppenheimer Gaining Popularity
in the Alternative History Movement
A genetic study recently has shown that the
oldest known human DNA lineages are those of East Africans. The most ancient
populations include the Sandawe, Burunge, Gorowaa and Datog people who
live in Tanzania.
Researchers found a very high amount of genetic
variation, or diversity, between the mitochondrial DNA of different individuals
in these populations.
The so-called African Eve represents the ancestral
mitochondrial genome that gave rise to all the different types seen in
people today.
Several of the ethnic groups sampled in the
study also live in countries surrounding Tanzania.
"It's entirely consistent with what we expected,"
said Dr Spencer Wells, a geneticist and author. "All the evidence is pointing
to East Africa as the cradle of humanity."
Dr Wells added that the data ties in well with
archaeological evidence of a long occupation of East Africa by modern humans
and hominids.
But Professor Ulf Gyllensten, a molecular biologist
at the University of Uppsala, Sweden, was cautious about claims that the
oldest DNA lineages were confined to East Africa.
"I wouldn't be surprised if Dr Tishkoff has
found old lineages there, but I think we're just skimming the surface,"
he said.
"Too little research has been done in Africa
to get a clear picture. I don't know why, because it's clear there is a
great resource of genetic diversity there," added Professor Gyllensten.
Dr Tishkoff's team have collected mitochondrial
DNA samples from 1,000 Tanzanians since they began their research in 2001.
Although the data comes from groups living
in Tanzania, the Burunge and Gorowaa migrated to Tanzania from Ethiopia
within the last 5,000 years.
Dr Tishkoff said Ethiopia was also a good candidate
for the region where modern humans evolved.
One of the populations sampled in the study,
the Sandawe, speak a "click" language like that of Khoisan people from
southern Africa.
The Khoisan were previously thought to possess
the oldest DNA lineages, but those of the Sandawe are older. This suggests
southern Khoisan originated in East Africa, according to Dr Tishkoff.
"That is surprising, because it has been presumed
that the oldest populations were in the south," said Professor Gyllensten.
Some of the oldest modern human archaeological sites in Africa are in the
south of the continent.
Dr Tishkoff said she planned to carry out further
research to narrow down the most ancient East African lineages.
In a new book Stephen Oppenheimer (who
earlier claimed civilization developed first around the Sunda shelf, the
now submerged continent of S.E.Asia) now writes in "Out of
Eden: the Peopling of the World" (UK) that an exodus took place 80,000
years ago via a little known southern route across the mouth of the Red
Sea. It also argues that living Malaysian tribes provide an extant link
of the route pursued from there, as modern humans beachcombed their way
to Australia in the space of 10,000 years. These theories form an account
of modern man's remaining journey around the world - to the Mammoth Steppe
heartland of Asia, to the now submerged continent of Beringia, and on to
the last great unpeopled lands of the Americas.
He also argues that only one, major exodus
from Africa 150,000 years ago by migratory African ancestors was the entire
non-African world in all its racial and cultural diversity ultimately populated.
Oppenheimer traces the evolution of modern humankind out of a common African
ancestry in opposition to the multiregionalists. Whereas they maintain
that archaic human populations, like the Neanderthals in Europe and Homo
erectus in the Far East, evolved locally into the races we know today.
In his book Oppenheimer argues that European Neanderthals, for instance,
are not ancestors of modern humans but cousins who have stemmed from the
same African root.
Stephen Oppenheimer recently has gained popularity
in the alternative History movement because rumor has it that Graham Hancock
is re-tracing the footsteps of Stephen Oppenheimer for his next book.
