the inherited genetic change over time that ensure survival of a species

a change in the frequency of alleles in a population over time

evolution occuring on a larger scale often over whole taxonomic groups over a long period of time

when in a relatively short amount of time a very large amount of species dies out

the process by which certain individual have more reproductive success due to being better adapted to their environment

-genetic variation occurs randomly among members of a species
-individuals traits could be inherited
-more individuals are produced than can survive in an environment
-only favorable traits would survive long-term due to competition
