Mailbag: Easier to receive than to give

Wed, 2009-08-05 12:37 -- John Hawks

With reference to "We have ways of changing behavior", a reader writes:

One thing anthropologists may want to study is the consequences of the fact that wheras it's usually much more efficient to change behavior by positive reinforcement, societies tend to favor either negative reinforcement or punishment.

Yes, I think that's very interesting isn't it?

Maybe it's because resources are usually limited? Easier to receive than to give. We tend to concentrate positive reinforcement on kin, which takes some of the pain away from resource transfer.

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.
