SciShow Tangents is the lightly competitive knowledge showcase from the geniuses behind the YouTube series SciShow. Every other Tuesday, join Hank Green, Ceri Riley, and Sam Schultz as they try to one-up and amaze each other with weird and funny scientific research... while not getting distracted. There will be tangents about video games, music, weird smells, surprisingly deep insights about life, and of course, poop, but it always comes back to the science.

episode 20: Charles Darwin
You might know him from his greatest hits: natural selection, Galápagos finches, and eating lots of the animals he studied… it’s Charles Darwin! This week, we’re talking about this famous biologist and some of the weirder science he did. What kind of books did he write after he published On the Origin of Species? Why was he so disgusted by fish spitting out seeds? And was it normal to write a letter to a scientist friend and ask detailed questions about barnacle sex?
