Descent with Modification-all species
living or non living, must have
descended by reproduction from preexisting species and that species must be
able to change over time

traits

characteristics, since they live in the same
environment.

can no longer breed with the original specie.

3
Geographical Isolation

can no longer mate because of a
barrier, such as a pond, valley or new
land formation
