Seed interviews Richard Wrangham

Thu, 2009-06-11 12:00 -- John Hawks

I've been reading Richard Wrangham's book, and I'll report on it when I've finished it. Meanwhile, SEED gives us another Wrangham interview. Wrangham points out that the measured calories in food from a bomb calorimeter are not what the body gets from digestion; and that less processed or raw foods are less bioavailable. Then Seed asks:

Seed: It’s ironic, then, that dieting supplements are some of the most processed foods out there—ground soy protein, shakes, etc.

RW: It’s exactly the opposite of what it should be! All those liquid protein diets…I mean, it’s hilarious. I’d be fascinated the find out the extent to which the proteins have been denatured and made even more calorie-rich by the addition of chemicals as well.

That's important, I think. I'm really enjoying the parts of the book that discuss the raw foodists.

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.
