Things You Would Like To See

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).

Although I am quite excited about Ardipithecus (more about the actual substance of the papers later) finally being published, there are a couple of things that really annoy the living daylights out of me. Continue reading

The More Things Change, The More They Stay The Same

I’m not sure what the point of this post is, I’m just kind of thinking out loud and I’m sure that those who know a lot more about genetic analysis will be able to point out some errors in all this, but hey, live and learn.
I’m sure my readers remember the paper that suggested some chimp/early hominin hanky panky? I bring this up because I am currently reading The Emergence of Modern Humans: Biocultural Adaptations in the Later Pleistocene. The book is a collection of essays based on a symposium called ‘The Biocultural Emergence of Modern Humans in the Later Pleistocene” held in 1986.
