Natural Selection

• Is a slight difference in an inherited trait of individual members of a species.

• The breeding of organisms for desired characteristics.

• Is an inherited trait that increases the organism’s chance of surviving and reproducing in its environment.

• The process where organisms that are best suited to their environment survive and pass on their genetic traits.
