Multiple Select

Darwin studied....

Select all that apply

Evidence to support the Theory of Evolution

Remember several observations provide evidence for evolution including; natural selection, artfacts in the fossil record, DNA similarties in organisms,  embryology, and  similarities in anatomy (body structure)

Theory is the explanation why you’re seeing something

Law is describing what you’ll see
