A. L. 822-1 was discovered in 2000 at Hadar, Ethipia. It is attributed to Australopithecus afarensis and is, at the time of discovery, the only complete skull of a female A. afarensis. The skull dates to approximately 3.1 MYA and is one of three that preserves both a cranium and a mandible (the others being A.L. 444-2 and A.L. 417-1).

The other day I stumbled across an interesting article by Kimbel and Delezene, published last year in the Yearbook of Physical Anthropology, called ‘‘Lucy’’ Redux: A Review of Research on Australopithecus afarensis. I’m just now getting around to reading it and one paragraph jumped out at me: (more…)

I am going to be very busy today so I won’t get an in depth post up on Australopithecus sediba until tomorrow. In the meantime three items jumped out at me so I thought I would, briefly, mention them.

Science Daily has an item concerning the Laetoli foot print study in PLoS One. One bit stands out:
The subjects walked both with normal, erect human gaits and then with crouched, chimpanzee-like gaits.
Film of the latter would be interesting – lord knows we were disappointed with last year’s Ardipithecus special on that score… Speaking of, why is the idea that some of our ancestors were bipedal on the ground but still spent a lot of time in the trees news?
And then there is this (also from Science Daily):
This morphology differs distinctly from our own genus, Homo, who abandoned arboreal life around 2 million years ago and irrevocably committed to human-like bipedalism.
I guess Homo habilis don’t count, eh? I hope the PLoS One article is better (I haven’t read it yet).

AL 288-1 casts a large shadow. The fact that such a large percentage of Lucy’s skeleton was recovered has overshadowed – at least in the public’s mind – that fact that a wide variety of fossil material was recovered at Hadar.

Back in April of 2007 I wrote a brief post on a paper by Rak, Ginzberg, and Geffin. I had meant to write a more in depth post about it but kept procrastinating.

My reaction on first hearing about this paper.
Having gotten that out of the way, I sat down and read the paper – which was published in PNAS. The paper was written by Yoel Rak, Avishag Ginzburg, and Eli Geffen. The short version is that Australopithecus afarensis displays mandibular traits that indicate it is too derived to be a human ancestor. The longer version is a little bit more interesting, although I am inclined to be somewhat skeptical.

I’m currently trying to get through a rather lengthy book – which I will be reviewing in a later post – so in the meantime here is one from the archives… I wrote it back in April of 2005 and think I would write it somewhat differently today. I’ve toyed with doing a similar post on the post-crania …
One of the most aggravating things one can hear, if one has any training in paleoanthropology, is that the australopithicines were nothing but glorified apes. So let’s study the issue (hey, I have to justify the name of this blog, okay! Which means more hominids.) The first set of pictures below is a frontal view of A. afarensis, a chimp, an orang and a gorilla.

Back in August, 2005, I wrote a post on Dinosaur Embryos, Growth and Human Evolution. One section of the post discussed attempts to study the growth patterns of KNM-WT 1500, in particular, and Homo erectus in general. I followed the discussion with:
More intriguing is the possibility that this type of analysis could be extended to earlier fossils. Interesting fossils have been found in Drimolen, South Africa (about five years ago). The finds consisted of the bones of two infants. One was 2-3 years of age, the other 8-10 months. One is tentatively assigned to the genus Homo, the other to Australopithecus robustus (the interesting thing about the A. robustus infant was that a lot of the robustus traits were clearly visible on the fragments – indicating that even early in life their are species differences among the australopithecines). Although the finds were fragmentary and only few bits of the crania were found one wonders if in a few years the above type of analysis could be extended to these fossils as well.
