THE discovery of human footprints, preserved by volcanic ash, have put back the likely date that the American continent was colonised by Man by almost 30,000 years, British scientists say.
The prints, found by the scientists at the edge of a lake in Mexico, are thought to be about 40,000 years old. Their discovery upsets the widely accepted theory that Man first reached America across a land bridge, now covered by the Bering Sea, 11,500 years ago. Casts of the footprints reveal that a community of Homo sapiens lived in the Valsequillo Basin, near Puebla in central Mexico. Their feet ranged in size from those of small children, aged about 5 or 6, to adults who would have fitted size eight shoes.
The prints were found at the bottom of an abandoned quarry and were preserved in volcanic rock. From the size of the prints, researchers from Liverpool John Moores University and Bournemouth University estimated that the adults ranged in height from 3ft 9ins to 6ft. Almost 270 prints were found at the site, two thirds of them human and the rest from animals including mammoths, an extinct species of camel, prehistoric cow and deer. The Liverpool and Bournemouth team discovered the footprints in September 2003 but have only recently had confirmation of their age from scientists at Oxford University. Dating techniques included radiocarbon dating and optical stimulated luminescence.
Until now it was widely believed that Clovis Man was the first human to set foot on the continent at the end of the last Ice Age. Previous academic research has suggested, however, that human occupation of the American continents may have begun several thousand years earlier.
The footprints are the first evidence of earlier colonisations and would suggest that the first settlers reached the West Coast from Japan or other Pacific Ocean communities.
Professor Matthew Bennett, of Bournemouth University, said yesterday: Our evidence of humans in America 40,000 years ago is irrefutable.
He accepted that there would be resistance to the theory that the original migration was not over the Bering Sea: It is quite controversial. They are not very happy in North America. They are very wedded to the idea of colonisation 11,500 years ago.

That does indeed appear to be the case. Scientists should welcome new data, but unfortunately many have emotional/financial attachments to old ideas.

Six feet, eh? Kinda argues against the fact that evolution is making us grow taller.
Well, except that we range to upwards of seven feet nowadays..
Average height is still around 6 feet. It is somewhat more than it was a hundred years ago, but that can easily be put down to a changing diet. The 7 foot is still highly unusual. In fact, anything above about 6'3'' is unusual.
The average height of these people, in case you didn't read properly, appears to be around 5 feet, which is where it should be.
That's gonna leave a mark I'm afraid. Liable to bunch up some underwear too.
Any idea, is this the oldest evidence now?
I seem to recall that sites on the eastern seaboard are this age or older, but there hasn't been definite confirmed carbon dating..
If early man reached america, say, 50K years ago across the atlantic, then he could very well have spread down the coast to Mexico/Central America, etc..
Not ruling out the Japan-Taiwan-Polynesian hypothesis in the article, just think either, or both is possible..

Footprints preserved in volcanic ash.
The footprints were made shortly after the deposition of the Xalnene ash and were preserved as trace fossils by the relatively fast deposition of fine-grained lake-sediment as the lake later transgressed across the site.

This will change the entire assumed history of the casino industry.
So who were they, and what happened to them? If they really are 40K years old then genetic and other data indicates that they are not the ancestors of today's American Indians. Instead, they must have been from an ealier group that went extinct.
Oddly enough, the footprints were headed north.
There is some disputed (of course) evidence in a cave in South America at 50-55,000 years old. It may not be so disputed after this find. Dilahey(sp) is arguring for a 30,000 date at or around the Monte Verde site.
