Skip to comments.Human ancestors walked comfortably upright 3.6 million years ago, new footprint study says [Laetoli]

A comparison of ancient and contemporary footprints reveals that our ancestors were strolling much like we do some 3.6 million years ago, a time when they were still quite comfortable spending time in trees, according to a study which will be published in the March 22 issue of the journal PLoS ONE... Although some researchers have argued that the 4.4 million-year-old ancient human Ardipithecus ramidus ("Ardi") described in October 2009 was adept at walking on her hind legs, many disagree... Likely left by Australopithecus afarensis, the same species as "Lucy," these prints show an upright gait, but it has remained controversial just how fluid and modern this creature's walk would have been. "Based on previous analyses of the skeletons of Australopithecus afarensis, we expected that the Laetoli footprints would resemble those of someone walking with a bent knee, bent hip gait typical of chimpanzees, and not the striding gait normally used by modern humans," David Raichlen, an assistant professor in the Department of Anthropology at the University of Arizona in Tuscon and lead author on the study, said in a prepared statement.

The footprints weren't left by a critter like Lucy. The existence of this obvious problem has taken some people 30 years to admit.

That’s because human ancestors were human......
Not too sure how many scientists buy into the 3.6 M yr. timeline though?

As opposed to walking on her “Front” legs?
The Scars of Evolution:"The most remarkable aspect of Todaro's discovery emerged when he examined Homo Sapiens for the 'baboon marker'. It was not there... Todaro drew one firm conclusion. 'The ancestors of man did not develop in a geographical area where they would have been in contact with the baboon. I would argue that the data we are presenting imply a non-African origin of man millions of years ago.'"
What Our Bodies Tell Us
About Human Origins
by Elaine MorganThe Neandertal EnigmaFrayer's own reading of the record reveals a number of overlooked traits that clearly and specifically link the Neandertals to the Cro-Magnons. One such trait is the shape of the opening of the nerve canal in the lower jaw, a spot where dentists often give a pain-blocking injection. In many Neandertal, the upper portion of the opening is covered by a broad bony ridge, a curious feature also carried by a significant number of Cro-Magnons. But none of the alleged 'ancestors of us all' fossils from Africa have it, and it is extremely rare in modern people outside Europe." [pp 126-127]

Hey, they might have had a circus back then. Geez.
Yeah, sure! All of this crap is always proved to be false.
Dude, you can't walk upright worth a damn after 3.6 million years of practice?
Hugely, very old.
Along the same mindset, record snowfalls and freezing temps throughout the world are caused by global warming.
Thanks, I concur.

Step right up. See the four legged humans. They walk, they talk, they do amazing tricks... step right up, only a dollar.
Looks like a cloven hoof to me. Walking upright?
Whomever it was, it looks like he suffered from bunions probably caused by too tight fitting high heeled shoes.
