A "lost tribe" that reached America from Australia may have been the first Native
Americans, according to a new theory.
If proved by DNA evidence, the theory will break long established beliefs about the
southerly migration of people who entered America across the Bering Strait, found it
empty and occupied it.
On this theory rests the belief of Native Americans to have been the first true
Americans. They would be classified to the ranks of escapee, beaten to the New World by
Aboriginals (土著人) in boats.
To a European, this may seem like an academic argument, but to Americans it is a
philosophical question about identity, Silvia Gonzales, of Liverpool University said.
Her claims are based on skeletons found in the California Peninsula of Mexico that
have skulls quite unlike the broad Mongolian features of Native Americans. These narrow-
skulled people have more in common with southern Asians, Aboriginal Australians and people
of the South Pacific Region.
The bones, stored at the National Museum of Anthropology (人类学) in Mexico City,
have been carbon-dated and one is 12,700 years old, which places it several thousand
years before the arrival of people from the North. "We think there were several migration
waves into the Americas at different times by different human groups," Dr. Gonzales said.
"The timing, route and point of origin of the first colonization of the Americas remains
a most contentious topic in human evolution."
But comparisons based on skull shape are not considered conclusive by anthropologists,
so a team of Mexican and British scientists, backed by the Natural Environment Research
Council, has also attempted to take out DNA from the bones. Dr. Gonzales declined yesterday
to say exactly what the results were, as they need to be checked, but indicated that they
were consistent (一致) with an Australian origin.
