available for a large population.
 Habitat: food, water, shelter, space
Natural Selection

traits will survive.
 Example: Food source determined
which finches survived on each
island.
Adaptation
 Inherited trait (characteristic, quality)
that increases an organism’s chance or
survival and reproduction.

survived and reproduced.
Evolution
