Proteins play countless roles throughout the biological world, from catalyzing chemical reactions to building the structures of all living things. Despite this wide range of functions all proteins are made out of the same twenty amino acids, but combined in different ways. The way these twenty amino acids are arranged dictates the folding of the protein into its primary, secondary, tertiary, and quaternary structure. Since protein function is based on the ability to recognize and bind to specific molecules, having the correct shape is critical for proteins to do their jobs correctly. Learn more about the relationship between protein structure and function in this video.

Zoologist Dan-Eric Nilsson of the University of Lund in Sweden explains how the complex human eye could have evolved gradually from a primitive light-sensitive eye-spot.
Finally a game half open. You start with a small creature and when you make offspring you go to an editor to design them. At any time the game populates the system with creatures designed by other players. First 2d, then 3d water, then walk
