Digestive evanescence

Also in The Guardian, "Strange but true: science's most improbable research" includes some taphonomy:

If you like shrews, especially if you like them parboiled, you'll want to devour a 1994 study published in the Journal of Archaeological Science. Called Human Digestive Effects on a Micromammalian Skeleton, it explains how and why one of its authors – either Brian D Crandall or Peter W Stahl; we are not told which – ate and excreted a 90mm-long (excluding the tail, which added another 24mm) northern short-tailed shrew (Blarina brevicauda).

I've always been fascinated by the evidence for hyena digestion on Pleistocene faunal remains -- they crunch the bones and their stomachs etch the pieces into all manner of lozenge-like detritus. But I hadn't thought much about human shrew-eating and the total dissolution of tiny toe bones.

Because who does think about that, really? I mean, besides zooarchaeologists.

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.
