Paleoanthropologist Tim White, professor of integrative biology at UC Berkeley, said he was not surprised at the new finding.
"The evidence (the British team) has provided in their arguments that these are footprints is not sufficient to convince me they are footprints," said White, who did not contribute to the new study.
"Other creatures do have "faces" which identify themselves as individuals."
Do you talk to the animals or something? How do you know that?

In total 269 human and animal prints were discovered, preserved in coarse ash. Approximately 60% of the prints were human, with 36% of the human prints classified as children’s because of their size. Several types of animal prints were also identified including dogs, big cats and animals with cloven feet, possibly deer, camels or bovids. Several short trails of footprints are visible in some parts of the quarry.
"I am amazed that they are still flogging that dead horse," said Paul Renne
"Very old human occupation of the Americas is possible," he said, "but if there were indeed people here that long ago, what happened to them in the next 25,000 years?"
"In this time, surely the population should have increased, and this would bring the presence of a high quantity of sites 16,000 to 20,000 years old," he said by email.
Crisscrossing the lakebed, they saw tracks, an ash field littered with hundreds of impressions that resembled footprints from adults and children, " along with birds, cats, dogs and species with cloven feet," as Nature magazine later reported. The team led by geoarchaeologist Silvia Gonzalez of the United Kingdom's Liverpool John Moores University, suspected the track's makers had fled an ancient eruption of the looming Cerro Toluquilla volcano, leaving their tracks in the now-famous "Xalnene Ash."
A number of papers flew back and forth, some supporting the Argon results and one confirming the younger luminescence date. But in the latest turn, the Journal of Human Evolution paper led by Darren Mark of the Scottish Universities Environmental Research Centre, and co-authored by Gonzalez, concedes the fight, replicating the Argon results from Renne's lab.
So, does that rule out the chances that people emigrated into the America's further back than 15,000 years ago? Nope, says Mark, it just means there is no evidence for it.

Fix your links.
Your posting have no scientific value.
You asked who is Renne, see the original post for a link to his accreditation.
You have asked me to fix links, why don't you ask the programmers to fix the editor because Web Archive links from the way back machine will not work in this editor.

Why do hundreds of millions of dogs of all varieties have slightly different faces?
Because we have selectively breeded them together over many successive generations...
Just like the aliens have selectively breeded us by manipulating and mixing the genetic materials of prehistoric humans with their own dna over many generations and they still are doing it to us now,thats why people all over the world are abducted by aliens and experimented on...
We were made in their image...
And remember that people see things differently,what looks pretty to me,might appear ugly to someone else...
Beauty is in the eye of the beholder...

With the help of the so called Thatcher illusion, scientists of the Max Planck Institute for Biological Cybernetics in Tübingen, Germany, have examined how people and macaque monkeys recognize faces and process the information in the brain. They found out that both species perceive the faces of their kin immediately, while the faces of the other species are processed in a different way.

Arg 1 can be ruled out quite easily, the rest, not so much.
Regarding arg 1, many species can deseminate between each other quite easily. It has been determined that sheep can tell the difference between each other simply by the face.
www.thenakedscientists.com...
We're very interested in finding out and understanding whether sheep are in many way like humans in the way that they use facial cues to recognise each other.
but we also derive emotional information from facial expressions. It occurred to us to ask the next question, which was if sheep can recognise and use faces, can sheep use faces to recognise emotional states? We looked at this not only in sheep, but looked at whether they can identify emotion in their human carers.
So who is Renne and why should his dates be considered?
That has nothing to do with identity. Animals use smell to identify each other and mothers identify the cry of their children as well as the scent.

The perceived differences in peoples faces are very slight when looked at as an entire species of seven billion faces and when people see eachother from a one on one,individual level,certain differences that one person sees,the other person may not notice at all...
If you and i looked at the same person at the same time,i'll clearly notice and see varying aspects and differences that you might not see...
And no one will ever be able to look at and keep a photographic record of the faces of seven billion people,to accurately compare and judge their similarities and differences and so surely there must be many,many people who have near identical faces impossible to tell apart,who will never look at eachother and will never know...

Why do humans all have different faces when no other form of life has different faces including apes?
Arg 2) Why are there elongated skulls in Peru which have no fontanel? In fact their skulls are not plated in the same way homo sapiens are, In fact then, they are not homo sapiens. Not even close. So where did they come from and what is the evolutionary argument regarding them?
And if you say these are skulls that have been modified by planking etc as per common practices of South American Indians that is not true. Those skulls are easily identified. If you want more info look it up. Its there.
Peruvian anthropologist Renato Davila Riquelme has discovered the remains of an unidentified creature with a "triangle shaped" skull nearly as large as its 20-inch-tall body. [CORRECTION: 50-inch-tall body]
