What are the four steps of natural selection?
overproduction variation selection competition

What is speciation?
formation of new species due to a change in the frequencies in specific genes in a population

population vs. food source

What are vestigial organs?
Organs that you could remove from your body and still live.

Explain what overproduction is.Each species produces more offspring that can survive
Each species produces more offspring that can survive
200

What is biochemistry?
DNA with more similar sequences suggest species are more closely related
300
Why is variation important? Variation of types of species some will survive
Variation of types of species some will survive
