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 25: Mutation with Trace Dominguez
This week, we’re joined by Trace Dominguez from the YouTube channel Uno Dos of Trace to talk about genetic mutations! Tiny changes in an organism’s DNA sequence can lead to big variations or absolutely nothing. It’s just a roll of the dice! So what mutations have shown up in modern humans—different bones, livers, or even eyeballs? What is “foreign DNA” and where does it even come from? And can anybody name as many X-Men as Sam?
