Composite tools

Sun, 2012-10-14 21:26 -- John Hawks

What if you took flaked stone implements, scanned them in three dimensions, designed specially fitted accessories, which you then printed with a 3-d printer and assembled into a composite? "modern stone + flint tools by ami drach + dov ganchrow".

through a method of three-dimensionally scanning and printing, the ancient artifacts are digitally outfitted with custom-designed handles, encapsulating the rugged forms in a perfectly enclosed case. by juxtaposing the polarities of the manufacturing processes in computer generated forms, an intersection of material technologies and functionality coincide on a tangible scale.

These are elegant and well-designed, truly art. Still, despite the fancy fabrication, the concept itself was known to the Neandertals.

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.
