Excerpt:
“Ever wonder why there are more bumble bees near towns than in the country? Probably not–but Darwin did. He discovered that field mice destroy bees’ nests. He reasoned that there are more cats near towns to destroy mice, fewer mice to destroy bees’ nests and therefore more bumble bees. Darwin called it the process of natural selection—Automatic Control Engineers call it a ‘feedback sequence’.”
