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?
