In this episode of Crash Course Biology, we ll learn about the ways population genetics reveals how groups of living things evolve by comparing genetic similarities and differences. We ll discover the most genetically diverse species of all (hint: it s not us, find out why race isn t the biologically valid category we ve made it out to be, and learn there s much more in our DNA that we share than that sets us apart.

The origin of race is a disturbing but interesting one. It has its origins from the Crusades and its early form was used to justify the wars to the Christian world. As time went on, and science more understood, race science eventually began to form to justify slavery and segregation. Only now we are seeing this whole facade fall apart. The ruling classes of the past used it to do horrible things to keep control over certain populations, but now that we're becoming more united as a species we're realizing the absurdity of the whole concept.

I'm a little disappointed with this episode. There's a lot of good, like the coverage of genetic diversity, clines & ancestry, etc. But a lot of it is overshadowed by racial bias and sociology. I'm not saying those topics shouldn't be included, but it feels shoe-horned in. I would equate it to having a video on the causes of World War I, but a quarter of the video is dedicated to just the Opium Wars. It's imbalanced for the content.

growing up christian was very harmful for my education on how this stuff worked. this was never explained but we were just supposed to believe all humans came from two white people. I love your vids!

That skin colour map is def wrong. Pretty sure the only white people in south africa are not indigenous to south africa but rather european

Are doppelgangers genetically identical though, like what happens in the cheetah population because the gene pool is so small?
