Document Summary

We do not know what the final product of a species evolution is therefore we do not know how far along they are -: all species will continue to evolve -> Some species will go extinct and end their evolution -> Environmental change is needed to cause a change in a species -: if you introduce a spontaneous mutation into genetics of species that will change the species -> The environment needs to select that mutation in order for the species to change -> What is evolution: the process by which a species as a whole changes and develops to be better suited to their niche, a theory of speciation. Speciation is when a species turns into multiple species. Evolution is not the only theory of speciation: response to selective pressures. What is a species: groups of animals that can reproduce and create viable offspring. Offspring that can successfully reproduce with each other.
