        Evolution 101

        Learn how evolution is responsible for the explosion of Earth’s biodiversity with this video from NOVA’s Evolution Lab. Every creature that’s ever lived, including you, has been shaped by the powerful force of evolution. One mechanism of evolution, natural selection, favors organisms that are better equipped to survive and reproduce, not necessarily the biggest or strongest organisms. Over time, evolution propagates traits that improve an organism’s chances of survival and reproduction. Phylogenetic trees are one way of representing evolutionary history. The Evolution Lab gives students a chance to create phylogenetic trees to track changes in DNA and expressed traits.
