They became extinct due to global warming and have not been found since 1989. Evolution - > change over time but scientists refer to it as biological evolution modifications in the appearance, functioning or behaviour of organisms, comes from random genetic changes or directed by natural selection. Natural selection - > traits that enhance survival and reproduction are passed on more frequently to future generations.

Individuals of the same species vary in their characteristics.
