DNA TESTING
ON 24,000-YEAR-OLD SKELETON, REVEALS THAT, NATIVE AMERICANS COULD BE PARTLY
DESCENDED FROM EUROPEANS
DNA extracted
from a Young Boy who died 24,000 years ago, could prove that the first
Native Americans were European. The Genome of the Four-Year-Old Boy, who
died in South-Central Siberia, is the Oldest Sequenced to date. It
provides an insight into Origins of Native Americans, whose Ancestors are
believed to have travelled across Siberia into the Americas, during the Ice
Age.
Writing in
the Journal Nature, the Researchers claim that around 30% of modern Native
American Ancestry, comes from the Young Boy’s Gene Pool. ‘The result came as a
complete surprise to us, said Professor Eske
Willerslev from Copenhagen University who led the study. ‘Who would have
thought that present-day Native Americans, who we learned in School derive from
East Asians, share Recent Evolutionary History with Contemporary Western Eurasians?’
The 24,000 Year-Old
Boy was unearthed in the 1920s by Russian Archaeologists near the Village
Of Mal’ta, along the Belaya River
in Siberia. Scientists from Copenhagen University in Denmark took a sample from
the Boy’s Arm Bone, extracted DNA from it and compared it to existing Native
American Populations.
They found
that DNA from the boy’s Y chromosome and from the mitochondria (the energy factories of the cells) were of types found today in a region encompassing Europe, West and
South Asia and North Africa. Interestingly, the boy showed no similarities with
populations such as the Chinese, Koreans or Japanese. This Puzzled Researchers as
today’s Native Americans, are closely related to East Asians.
One theory is
that the boy’s future relatives mixed with the Ancestors of East Asians at some
time after he died. This result paints a picture of Eurasia 24,000 years ago
which is quite different from the present-day context. The Genome of the Young
Boy, indicates that Prehistoric Populations related to modern western Eurasians,
occupied a Wider Geographical Range into Northeast Eurasia, than they do today.
‘It tells us
that these individuals that were living in Siberia -in South-Central
Siberia 24,000 years ago- their Genes
contributed to first Americans’ Genes,’ Texas A&M University researcher Kelly Graf. ‘I think what it does is it
helps to clarify some things and the first is that the Americans came from
Siberia. ‘Some Archeologists had suggested that the First Americans could have
come from Europe directly from Transoceanic Migration, and I think that this
does a Fairly Good Job Clarifying that: it was a Land Migration or at least a Coastal
Migration through BERINGIA
The 24,000 Year-Old
Boy was Unearthed in the 1920s by Russian Archaeologists near the Village Of Mal’ta, along the Belaya River in Siberia.
The findings
dispute earlier theories that American Ancestors came from Europe, instead
suggesting they came from Siberia and traveled by an Earlier Land Attachment, in
the Bering
Sea.
Previously, Researchers
had thought that people came from Europe into East Asia, and then entered
Siberia from the South. The latest results suggest the Siberian Inhabitants, may
have come from the West and that there were Multiple Waves of Migrations in
Asia around this time. The Research could also help explain some Mysteries
Surrounding Native American Origins. For example, some Early American skeletons
–such as the 9,000-Year-Old Kennewick Man from– have physical features that,
some believe, are Typically European.
HOW NATIVE
AMERICANS TRAVELLED FROM SIBERIA DURING THE ICE AGE
The Latest
Research Paints a Picture of Eurasia 24,000 years ago, which is quite different
from the Present-Day Context. The genome of the Young Boy indicates that
prehistoric populations related to modern western Eurasians occupied a wider
geographical range into northeast Eurasia than they do today. Scientists
believe Most Native Americans are Descended from a Small
Group of Migrants, that crossed a ‘Land Bridge’ between Asia and
America, during the Ice Ages 15,000 Years Ago.
These Immigrants
are known as the ‘FIRST AMERICANS’, which Populated most of North and South
America.
The latest
results suggest the Siberian Inhabitants, may have come from the West and that
there were Multiple Waves of Migrations in Asia around this time.
