Oldest American Skull Found in Mexico
MaximumBob writes "While digging a well near the Mexico City airport, crews found this skull, believed to be the oldest human skull ever found in the Americas. What's especially exciting is that since it was found outside the United States, it's not subject to U.S. laws which allow local tribes to rebury remains and keep them from being studied. The skull will be studied by scientists and may shed new light on alternatives to the "land bridge" hypothesis of American settlement."
This find is being interpreted as (very preliminary) evidence for a newer theory - that the Americas were inhabited by people related to the Ainu, long BEFORE the people we now call "Native Americans" showed up.
What happens to that 'Native Americans get dibs on any old bones found in the U.S.' law if the earlier-Ainu theory pans out? This could get into some really interesting "politically unacceptable scientific facts"...
It's easy to make up & spread cool- and credible-sounding stuff. Finding & checking hard facts is hard work.
This story seems somewhat confused and contradicts other things I have read on the subject. I am not convinced the actual interpretation of this find is very reliable.
The most modern theories about the origns of humans in north america, prior to this find, as far as I understand them are as follows. The first humans came across the land bridge between alaska and asia during the last ice age, about 17,000 years ago. They were caucasians, closely related to the Jomon, the prehistoric inhabitants of Japan, whose modern couterparts are the Ainu of Hokkaido. They penetrated throughout north and south america in a 1,000 years or so. Later, about 3,000-4,000 years ago, another group crossed the bering strait in boats. These people were closely related to the modern Chinese and Mongolian people and only penetrated north america. Their descendents are principly the Eskimo and Aleut, but some penetrated futher south such as the Navajo. See here for details.
This find seems to just seems to add extra conformation to the above hypothesis. Finding a 13,000 year old skull does not mean that there had to be human in the americas 25,000 years ago. Nor does the skull contradict the theory that the first humans used the land bridge to cross to alaska during the last ice age. The evidence of camps -- man-made tools, a human footprint and huts dating back 25,000 years are totally separate from this and obivously need explaining, but this find has no real bearing on that debate.
