Knapping a handaxe

Thu, 2009-03-05 10:00 -- John Hawks

Science magazine's "Origins" blog is running a little feature by archaeology student Steven Goldstein on how to knap a handaxe.

I’ve had a lifelong interest in archaeology, and to better understand the process of making chipped stone tools, I began teaching myself how to replicate them. I started with Oldowan tools and eventually moved up to Neolithic and New World materials. Here’s what I do, and what I think, while I make an Acheulean hand ax, which early humans created about 1 million years ago.

On the same topic, I continue to recommend Tony Baker's site, which takes a practical view of stone tool production from the perspective of an experienced knapper. His Acheulean essay in particular is a thought-provoking exposition of the idea that handaxes were flake cores rather than finished artifacts.

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.
