“Evolution is science's greatest discovery, the most trial-and-error tested, time-proven success and sustainability system that has ever existed and the best documented "theory of everything" that currently exists. “ --Lawrence Wollersheim

The third greatest discovery in the history of science will eventually be widely recognized as; evolution is progressive. It has an overall directionality in spite of its many meanderings, retrogressions, dead ends and extinctions.
