Which of the following misconceptions about evolution can be refuted with the molecular evidence that is being collected through DNA analysis?
30
Evolution is not observable or testable, thus it is not science.
There are no transitional fossils.
Evolution is a theory about how life originated.
Evolution proposes life changed as a result of random events; traits are too complex to have originated by chance alone.
