Richard Dawkins discusses 'biomorphs' in 1991

Evolutionary biologist Richard Dawkins wrote The Selfish Gene 40 years ago, in 1976, and The Blind Watchmaker 30 years ago, in 1986.

For the latter book, he developed software that featured "biomorphs": simple shapes, representing plants or animals, which could be "bred" by clicking on them.

The computer program offered a demonstration of how artificial selection works.

He presented the software in this footage, from the Royal Institution Christmas Lectures 1991 (Episode 2: Designed and Designoid Objects).
