100
They help us learn what was living during past eras.
What are fossils?
200

What is the environment?
200
This type of reproduction results in greater genetic diversity.

400
They indicate good genes in a male, like a peacock's tail.
What is ornamentation.
400
Genetic variation is required for this to happen.

500
There may be many different ones for a single character in a population.
What is a trait?
500
It is the way speciation occurs.
