What is another name for survival of the fittest?

Answer 1

The Darwinian theory of survival of the fittest derived from his observations of Galapagos turtles. The turtles had to reach up high to find food in shrubbery, so the only ones that "survived" would be those that had longer necks. Over time the gene of long necks was passed on because all those turtles that had long necks had more of a chance of survival because they could reach more source of food. The organisms that were more fit for the environment survived. This also applies to: speed, mannerisms, length of wings, and ability to swim, plus many many others.
