Listeros,
In an article at National Geographic about the new finds concerning
the claimed 40,000 year old footprints in Mexico, archaeologists
expressed some skepticism about the new finds. Here are their
comments;
"I am amazed that they are still flogging that dead horse," said Paul
Renne, of the University of California, Berkeley's Geochronology
Center. Renne led that team that initially dated the Valsequillo Basin
strata.
"We are about to publish even more data showing that the rocks are 1.3
million years old and that the 'footprints' are not," he said by e-
mail.
Rafael Suárez of the Museo Nacional de Historia Natural y Antropología
in Montevideo, Uruguay, is more cautious—but also dubious.
"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.
James Dunbar, an archaeologist at Florida's Bureau of Archaeological
Research in Tallahassee cautions that carbon-14 dating in the 40,000-
year age range is often suspect, because the samples might include
"dead carbon," or carbon not originally from living organisms.
Dunbar is impressed, though, by the digital laser imaging system used
in scanning the footprints.
That method, he said by email, is a "very sophisticated way … to help
see features that are sometimes not detectable to the human eye."
