paleoanthropology, genetics and evolution

Is that a Jethro Tull song?

January's Discover magazine came in the mail; it has a list of the top 100 science stories of 2005. There are several paleoanthropology-related stories that I'll probably share later. But number 91 attracted special attention:

Flores Man Denied Status As New Species

Poor Flores Man just can't rest in peace. All year a controversy has raged about whether the bones found in 2003 on the remote Indonesian island of Flores represent a new species. Australian paleoanthropologist Peter Brown insists the skeleton is a new type of human who should be called Homo floresiensis. Others say he's [sic] simply a pygmy, five feet tall, who had microcephaly, a condition that results in a small, oddly shaped skull.

That's why Robert Eckhardt, a paleoanthropologist at Pennsylvania State University, and a team have intently analyzed the 18,000-year-old bones. The group's research papers, undergoing peer review, are unequivocal. "Homo floresiensis," says Eckhardt, "is not a valid new human species."

Brown is dismissive. "Robert Eckhardt is thick as a plank," he says....

Wow.

The short piece goes on to discuss the custody of the bones and the damage to them.

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.
