Australopith ancestry clarified

From UC Berkeley:

New fossils discovered in the Afar desert of eastern Ethiopia are a missing link between our ape-man ancestors some 3.5 million years ago and more primitive hominids a million years older, according to an international team led by the University of California, Berkeley, and Los Alamos National Laboratory in New Mexico.

The fossils are from the most primitive species of Australopithecus, known as A. anamensis, and date from about 4.1 million years ago, said Tim White, a UC Berkeley professor of integrative biology and one of the team's leaders. The hominid Australopithecus has often been called an ape-man because, though short-statured, small-brained and big-toothed, it walked on two legs unlike the great apes.

More primitive hominids in the genus Ardipithecus date from between 4.4 million and 7 million years ago and were much more ape-like, though they, too, walked on two legs.

"This new discovery closes the gap between the fully blown Australopithecines and earlier forms we call Ardipithecus," White said. "We now know where Australopithecus came from before 4 million years ago."

The fossil finds and an analysis of the hominid's habitat and evolutionary position are reported by White and co-authors from Ethiopia, Japan, France and the United States in the April 13 issue of Nature.

Probing the origins of humanity is actually a lot like being a dentist. The bones of our hominid ancestors tend to fall apart, leaving behind a smattering of shards. But teeth, made of enamel, can do a better job of withstanding the ravages of time. And teeth--particularly those of mammals--are not…
In 1978, a paleoanthropological team including Mary Leakey, Richard Hay, and Tim White made a startling discovery at Laetoli, Tanzania; in a bed of volcanic ash that would later be dated to about 3.5 million years old were the footprints of ancient hominids. The preserved trackway, found to contain…

In 1970, the natural history illustrator Rudolph Zallinger painted a picture of human evolution called "The March of Progress" in which a parade of hominids walked along from left to right, evolving from knuckle-walking ape to tall, spear-carrying Cro-Magnon.

If the DI was totally freaking over Tiktaalik, how bad will their freak be over this! HA!

I think that this is just one more piece of the dastardly "gap-filling" conspiracy on the part of the Evilutionist Hordes! They're clearly saving up these things, waiting until the Other Side says something silly about missing links (a short wait, mind you), and then releasing another one. I mean, having this come hard on the heels of the "fishapod"? Coincidence? Not likely.

Someone wanting to pontificate on and and give examples of "missing links" must be (in Tom Lehrer's phrase) as nervous as a Christian Scientist with appendicitis.

What's next?? :-)

Wow! Fascinating article! Thanks for the link to it! I found two things about the article (well more than that but I don't want to hog the thread). First, the citing of the Ward et al papers predicting that Ar. ramidus, Au. anamensis and Au. afarensis form an anagenetic series and the claim that White et al's paper tests this prediction (who says paleoanthroplogy can't make predictions)! Second, they relate it back to punk eq...fascinating stuff. Are you going to do a more in depth write up of the paper?

Nah, I'll kick it over to you. I'm pressed for time at the moment.

Cool! I have to go run an errand, but I'll have it up in a couple of hours...
