Mysteries of A. afarensis

Mon, 2008-10-06 12:00 -- John Hawks

In honor of Lucy's move to Seattle, Alan Boyle has a piece at "Cosmic Log" about Lucy and A. afarensis. It has a lot of questions and few answers, but may be interesting for students. And there's this passage involving Anna Behrensmeyer:

Even Johanson has said the First Family is as deserving of fame as Lucy. According to South African reports, he's trying to nail down the evidence for the cause of death by consulting with an expert on prehistoric predators.

In the past, investigators have suggested that the entire troop of hominids might have died in a flash flood, or were done in by a bout of food poisoning. But Behrensmeyer said the current prevailing theory is that they were the victims of a "surplus killing" by blood-crazed predators. "This is documented as a natural phenomenon," she said.

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.
