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..
Human left footprint showing toe impressions and slight heel impression.
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.
Rock shelter overlooking Valsequillo basin. Several early Holocene human skeletons were buried in the rock shelter.
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.

This one made the radio news this morning. Are the 'original inhabitants' of the New World getting anxious yet?
The persistent practice of underestimating human antiquity in the Americas, is a big problem (except for those who do it, of course), and I'm not going to call into question all geological dating practices, but be aware that these results will likely be derided as unreliable by some. Others will saddle on the results right away, in order to bury Clovis-First-and-Only in a well-deserved grave. However, if past practice is any guide, even if this date is accepted (with or without modification), it will become the new floor beneath which dates won't be accepted.Gods, Graves, and Scholars: The Story of ArchaeologyNow, several of these pyramids located at different sites from Tula to Monte Alban have been discussed, yet one of the most important has yet to be mentioned. This is the Pyramid of Cuicuilco, which stands on a mound 22.4 feet high, situated at the southern limits of Mexico City. The Pyramid of Cuicuilco rises up out of a weird landscape of darkly stony aspect. At one time the volcanoes Ajusco and Xitli (perhaps only the latter) erupted. The god within the pyramid was apparently remiss in diverting the glowing flood of lava that flowed about the pyramid, for half the structure was drowned in bubbling muck. The archaeologists investigating this phenomenon called on colleagues from another faculty, the geologists, for help. How old is the lava, they inquired. The geologists, not realizing that their answer was knocking a world picture awry, answered: "Eight thousand years." ...Yet late research is more inclined to consider it false.

The fathom was the distance fingertip-to-fingertip of a (Viking) man with his arms outstretched.
"genetic and other data indicates that they are not the ancestors of today's American Indians."
That's not true. Various mtDNA studies (which are inherently unreliable) yield estimates of the ingress of various populations (meaning, an assumed single individual; all other mtDNA lineages having died out) which overlap the age assigned to these prints. And the vast majority of these studies reveal multiple populations entering the Americas at different times. The artificial barrier of Clovis dating is long gone.
"A better diet is making us taller."
I remember from a couple of decades ago that there was some buzz that hunter-gatherers had been tall, then people shrunk as a result of agriculture limiting their diet, and now we're regaining the lost height.
Barefooted? Where was Nike or US Keds?
That makes perfect sense. A length of rope could be measured easily that way, while trying to compare it to height would be cumbersome.

Signs of an earlier American

We're good at fathoming things around here. ;')
Now I wonder...
There goes another 'proven' scientific theory down the drain.
Japanese, not Chinese. Chinese are affiliated with the Olmec in Mexico. Read the below, a good book too.
Nancy Yaw Davis
The Zuni Enigma
Did a group of thirteenth-century Japanese journey to the American Southwest, there to merge with the people, language, and religion of the Zuni tribe?
For many years, anthropologists have understood the Zuni in the American Southwest to occupy a special place in Native American culture and ethnography. Their language, religion, and blood type are startlingly different from all other tribes. Most puzzling, the Zuni appear to have much in common with the people of Japan.
In a book with groundbreaking implications, Dr. Nancy Yaw Davis examines the evidence underscoring the Zuni enigma, and suggests the circumstances that may have led Japanese on a religious quest-searching for the legendary "middle world" of Buddhism-across the Pacific and to the American Southwest more than seven hundred years ago.
Nancy Yaw Davis holds an M.A. from the University of Chicago and a Ph.D. in anthropology from the University of Washington. Author of numerous articles, she has long researched the history and cultures of the native peoples of North America. Her company, Cultural Dynamics, is located in Anchorage, Alaska, where she lives.
Generally, the height of a man is equal (or pretty darn close) to the length of his outstretched arms.
I didn't say that a better diet is making us taller. I just said that a different diet is having that effect. Considering the obesity and heart issues so prevalent today that didn't exist 100 years ago, I seriously doubt that we have a better diet today.
Well, if you want to debate whether our diet is "better" or just "different" in a broad sense, knock yourself out. But with respect to having enough calories and protein as children to reach our our biologically maximum height, our diets today are better. That the diets in many Western nations (and particularly the United States) far exceed the amount of calories and protein that we need to reach our biologically maximum height resulting in obesity is a different issue. My point is simply that many populations that were once considered genetically short were actually short because of nutritional problems, not biology, and given plenty of protein and calories, the children of people in those populations can grow quite tall. If you want to argue that we've exceeded the point of improvement and headed well into overconsumption causing a different set of problems, I'd probably agree with you.
I agree with you that it is not an evolutionary trait. But you might note that since it is a survival advantage, it does loosely fit the definition of "natural selection" - a prime argument used in evolutionary theses.

Oh, and in case you're wondering, I'm 6'1" and 190lbs so my position is not partisan ;-)

Ancient DNA from bones and teeth of 60 individuals from four extinct human populations from Tierra del Fuego-Patagonia (Selknam, Yamana, Kaweskar and Aonikenk) has been extracted and the mitochondrial DNA (mtDNA) amplified by using the polymerase chain reaction. High- resolution analysis of endonuclease restriction site variation in the mtDNA and sequencing of its hypervariable non-coding control region, revealed complete absence of two of the four primary mitochondrial haplotype groups present in contemporary Amerinds, namely A and B. In contrast, haplogroups C and D were found in all but one sample with frequencies of approximately 38% and 60%. These results, together with the decreasing incidence of group A in more southerly latitudes in the American continent and the absence of cluster B above 55 degrees North in America and Asia, argue that the first settlers entering America 21000-14000 years ago already lacked both mtDNA lineages.
