Natural Selection
... What’s the premise of Natural Selection - coined by Charles Darwin… 1. There is a struggle for existence Organisms must compete for limited resources - food, space, a mate. 2. Many more offspring are born each season than can possibly survive to maturity (overpopulation) 3. Their survival is based ...
