Sometimes referred to as "survival of the fittest," this process allows those traits which are most favorable to be passed on to the next generation and those which are not to be eliminated.

• genetic drift

• gene flow

• natural selection

• mutation

A spontaneous change in a gene or chromosome affecting the gene pool of a population is what?

• natural selection

NGSS.MS-LS4-4

This principle of natural selection explains that many offspring increase the chances of organisms to survive and those that cannot cope with the changes will become extinct.

• variation

• decent with the change

• adaptation

• overproduction
