Darwin's theory of evolution bbuilds opon the idea that mutations are random. Sometimes, a mutation happens that is slightly better fitted with the environment. Such a mutation will have a little higher probability to multiply. So in the long run, its survival probability should be higher, and eventually, the original population should disapperar.

The program builds a tiny world, starting with one single individual (blue), that spreads by distributing seeds in the surrounding locations. A seed may mutate, and the result will be two populations, one blue and one yellow (stronger).

To run the program
Start by clicking [Create]
A filled blue circle appears at some location.

Click the button [Generations] a number of times.

Each click gives on new generation, but by writing a number in the input field to the left of the button, each click may let several generations pass, e.g. 50.

Whenever you wish, you may induce a mutation (or more than one) by clicking [Mutation].

In the field to the left of the button, you may control the relative strength of the mutated individual as compared to the original. If you want the mutation to be weaker, use a negative value.

The result shows that generally, the stronger mutatation does not extinguish the original population. This indicates that the evolution is controlled by some other mechanism than Darwin's. One possibility is that the cells are able to cotrol rate and direction of the mutations.
