Critters is a brand new Mac-only artificial life program designed for students or anyone interested in evolution. The Critters develop solutions through evolution to the problems of finding food, breeding, and avoiding predators.
The shareware has a Mac-like interface and will work on any Power Mac. It allows the user to set the size of the universe and how it will appear on the screen and shows detailed statistics for the whole population so you can track the process of evolution.
A graph window shows data as far as 5,000 steps ago for analysis of values such as population, and the genomes of individual creatures can be viewed and edited. Universes can be saved or sent to another person and all the main windows can be captured as PICT files as a record.
Critters is $10 shareware and is downloadable now.
