This component of natural selection is the idea that members of the same species may have to compete with one another to survive
Competition
The more biological __________ species have in common with each other, the more related those two species are.

Evolution
This factor of natural selection is the idea that humans may impact where the species lives or breeds which may affect it's survival, like a city being built on a beach where turtles lay eggs
Changes in the Environment
We can look at the _______ of different species to compare their genetic codes and see how genetically similar they are to each other *Hint: found in the nucleus of cells
