The Darwin program version 2012. Darwin's theory of evolution based on the idea of random mutations. Occasionally, a mutation appears, that is slightly better adapted to the environment. Such a mutation is somewhat more likely to propagate. In the long run, it is therefore more likely to survive, and eventually, the original version disappears. The program builds a tiny world, starting with one single individual (blue), that multiplies by placing seeds in adjacent locations. A seed is able to mutate, and then a blue and a yellow population are competing for the available space. Running the program Start by clicking the button [Create] A blue circle appears at some location. Click the button [Generations] a number of times. Each click allows a number of generations pass. Normally, just one per click, but by typing another value in the box next to the button, you may let several generations (e.g. 50) pass for each click. When desired, you can let an idividual mutate. By default, the mutation will be one percent stronger than the original population. The value can be changed by typing a different value in the corresponding box. The results show that generally, the strong mutation will become extinct, rather than the original (weaker) population. The conclusion is that evolution is controlled of some other kind of mechanism, e.g. that the mutations are not random, but are controlled by the needs, causing genetic changes to occur simultaneously in a large number of individuals.
