Crash Course is the channel I was watching, specifically the Big History series. I LOVE Crash Course, but of course the nature of it is that they can’t get too detailed with any given subject. I kind of wish they drilled down into a couple of things more: 1) evolution of animals during the time between dinosaurs going extinct and the arrival of hominids, and 2) different types of hominids. So that’s the sort of stuff I want to learn about next.
