Biological Similarities
What is a vestigial structure?
How does evolution relate to climate?
Evolution relates to climate because the climate on earth is constantly changing and when that happens, species must evolve with it or go extinct.
How can a change in the environment cause an entire species to go extinct?
They can cause an entire species to go extinct because if the species is not fit to live in a certain climate then it can effect them greatly.
Ex: If the grass turned from yellow to green and a certain type of worm was colored yellow to blend, then they would not be able to blend into newly green grass.
Why would genetic diversity or variation in DNA help species better survive environmental changes?
Because if the species was diverse, then they would be better prepared to survive changes. They could survive longer in many environments because they could adjust easier if a portion of them was already fit to live in the new environment.
