Richard Dawkins created a series of computer programs in the 1980s designed to show how evolution works. This interactive site is based on his original code.

‘A few minutes of playing with this program gives you a hands-on, vivid feeling for how Darwinian selection works.‘

Your creature has a number of genes which you can tweak. Each slider represents a pair of genes. Increasing or decreasing a gene’s value will change the appearance of your creature.

Breeding your creature

When a biomorph has a child it inherits all the genes of its parent (it only has the one parent, for there is no sex), but with some possibility of random mutation. This is artificial selection (as opposed to natural selection) since you dictate which genes survive through breeding.
