Evolution 101 & how natural selection works – NOVA PBS

Watch more with these video collections:

What is evolution, how has it created Earth’s biodiversity, and how can a phylogenetic or evolutionary treea tree of life—help us better understand how different species are related? Learn some basics from this Evolution 101 video from NOVA, a companion vid to NOVA’s Evolution Lab interactive. From PBS Learning Media:

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.

Follow the video above with these supporting NOVA explainers: DNA Spells Evolution, Biogeography: Where Life Lives, and Fossils: Rocking the Earth:
