Weasel

This software app is an evolution simulation based on the evolution program in Richard Dawkins's book, The Blind Watchmaker, that shows the process of natural selection. The program got its name from Dawkins using the phrase from Shakespeare, "METHINKS IT IS LIKE A WEASEL" in the program. The program aims to demonstrate that the preservation of small changes in an evolving string of characters (or genes) can produce meaningful combinations in a relatively short time as long as there is some mechanism to select cumulative changes, whether it is a person identifying which traits are desirable (in the case of artificial selection) or a criterion of survival ("fitness") imposed by the environment (in the case of natural selection). Reproducing systems tend to preserve traits across generations, because the offspring inherit a copy of the parent's traits. It is the differences between offspring, the variations in copying, which become the basis for selection, allowing phrases closer to the target to survive, and the remaining variants to "die."
