Is a new method going to "shake up" hominid phylogenetics?

No.

Oh, you know I can't manage a one-word post here. I can't get the paper yet -- now Nature has moved to the annoying press-release-long-before-paper-appears model! But I haven't read anything in the press yet that makes any sense. Most stories (and here) just seem to be press-release-regurges.

To me, this is the key passage:

The team goes back over the same well-known set of specimens, but uses a different approach to analyse it, focussing in particular on a set of fundamental yet long-term changes in skull shape.

They took digital 3D images of the casts of 17 hominid specimens as well as from a gorilla, chimpanzee and H. sapiens.

Well, that certainly sounds like the way we teach 100-level hominid phylogeny labs when we only have 17 casts. But it doesn't sound very much like the kind of careful character analysis that ought to go into a test of a phylogenetic hypothesis.

UPDATE(2008/05/06): More thoughts upon reading the paper here.

Neandertals

For years, I've worked on their bones. Now I'm working on their genes. Read more about the science studying these ancient people.

Denisova

From a finger bone of an ancient human came the record of a completely unexpected population. My lab is working on the science of the Denisova genome.

Acceleration

The advent of agriculture caused natural selection to speed up greatly in humans. We're uncovering some of the ways that populations have rapidly changed during the last 10,000 years.

Malapa

Just outside Johannesburg, the Malapa site is producing some of the most exciting finds in human evolution. This site is the headquarters of the Malapa Soft Tissue Project.
