What’s the significance of a human tailbone? Allow Craig Savage to blow your mind with evidence for evolution backed by evolutionary theorist Charles Darwin.
Darwin combined truths of geology, economics, and biology to form his theory of natural selection. But did you know he wasn’t the first to consider evolution?
Natural selection explains how evolution occurs, but it can also explain why certain organisms (like sharks and crocodiles) haven’t changed in millennia.
Evolution occurs over millions of years, so how do new species emerge? Time is only one factor— the second factor is reproductive isolation.
Do you know how genetic variation takes place? Learn how the genetic material of an entire species changes (hint: it happens in populations, not individuals).
