Which of the following can be determined through the examination of fossils?

a) how a species has changed over time
b) why organisms follow specific mating rituals
c) how an organism hunts its prey
d) why organisms migrate the way they do

The answer is A. If you took the fossils of two species from long ago up until today, you could see differences. For example, a human. We once started out as monkeys, and then gradually over time formed into what we are today. Hope this could help!
