The bugs are equipped with several genes, modifying mainly how they search for food and how their energy is expended. If a bug runs out of energy, it dies. If a bug reaches the reproduction energy threshold it reproduces introducing mutations into the offspring's genes. This is primarily a simulation that can be used to show that mass populations can and will alter their overall genepool to adapt to an environment, the fundamental theory necessitated in evolution. Bugs is freeware and will run on any Macintosh computer.
