Australopithecus sediba in National Geographic

Mon, 2011-07-18 15:21 -- John Hawks

National Geographic has posted text from Josh Fischman's August article about Australopithecus sediba: "Malapa fossils".

This raises the possibility, says Berger, that all the hominins—at least four are now known from the site—died weeks or even days apart, and therefore may have known each other in life. The rapid burial also caused their flesh to take longer to decompose, packaging the skeletons in death as they were arranged in life, right down to tiny bones of the hands and feet. Indeed, the rapid entombment may have preserved some of the skin itself, on top of the boy's skull and on the woman's jaw near the chin—something never before seen in a hominin fossil.

It's pretty cool to be here with the fossils and the people involved in the story right now. The story nicely features many members of the extensive team involved in the preparation and analysis -- a process that has unfolded so far in less than three years from the discovery of the site.

The article emphasizes what may be the central scientific problem posed by A. sediba: what it means for early Homo. As I wrote last month, the origin of Homo is by far the most interesting problem in human evolution right now.

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.
