The strong linkage
between these populations has always been empirically apparent. This
finally settles what has been obvious and clearly establishes the
time line. Thus later incursions merely topped up an already
European palette.
What has been more
troubling has been the avoidance of this topic from the academics.
Now DNA research is systematically reducing sophism for what it truly
is. Ignoring and even denying obvious evidence should be made into a
capital crime in academe.
It all starts with
denigrating the technical abilities of our ancients by denying them
the natural wits we are all born with. We have today plenty of folks
doing more with less just to show it is possible. How many row boats
have to make a summer trip across the Atlantic?
Native Americans
and Northern Europeans more closely related than previously thought
Using genetic
analyses, scientists have discovered that Northern European
populations—including British, Scandinavians, French,
and some Eastern Europeans—descend from a mixture of two
very different ancestral populations, and one of
these populations is related to Native Americans. This
discovery helps fill gaps in scientific understanding of both Native
American and Northern European ancestry, while providing an
explanation for some genetic similarities among what would otherwise
seem to be very divergent groups. This research was published
in the November 2012 issue of the Genetics Society of America's
journal Genetics.
According to Nick Patterson, "There is a genetic link between the paleolithic population of Europe and modern Native Americans. The evidence is that the population that crossed the Bering Strait from Siberia into the Americas more than 15,000 years ago was likely related to the ancient population of Europe."

a second. The population that crossed the Atlantic more than 15,000
years ago had the island of Lyonese to step on from the edge of
Ireland to the edge of the Grand Banks as well as ample ice to rest
on. - arclein ]
According to Nick
Patterson, first author of the report, "There is a genetic link
between the paleolithic population of Europe and modern Native
Americans. The evidence is that the population that crossed the
Bering Strait from Siberia into the Americas more than 15,000 years
ago was likely related to the ancient population of Europe."
To make this discovery, Patterson worked with Harvard Medical School Professor of Genetics David Reich and other colleagues to study DNA diversity, and found that one of these ancestral populations was the first farming population of Europe, whose DNA lives on today in relatively unmixed form in Sardinians and the people of the Basque Country, and in at least the Druze population in the Middle East. The other ancestral population is likely to have been the initial hunter-gathering population of Europe. These two populations were very different when they met. Today the hunter-gathering ancestral population of Europe appears to have its closest affinity to people in far Northeastern Siberia and Native Americans.
The statistical tools for analyzing population mixture were developed by Patterson and presented in a systematic way in the report. These tools are the same ones used in previous discoveries showing that Indian populations are admixed between two highly diverged ancestral populations and showing that Neanderthals contributed one to four percent of the ancestry of present-day Europeans. In addition, the paper releases a major new dataset that characterizes genetic diversity in 934 samples from 53 diverse worldwide populations.
"The human genome holds numerous secrets. Not only does it unlock important clues to cure human disease, it also reveal clues to our prehistoric past," said Mark Johnston, Editor-in-Chief of the journal GENETICS. "This relationship between humans separated by the Atlantic Ocean reveals surprising features of the migration patterns of our ancestors, and reinforces the truth that all humans are closely related."
