When Three Species Combine: Multi-Species Hybrids

TL;DR

Hybrids of multiple species, like mules and coywolves, offer insights into genetics and adaptation.

Transcript

This episode is sponsored by Skillshare. [♪ INTRO] We generally think of species as discrete groups of organisms that simply can’t interbreed. But hybrids, the offspring of two species, do happen. And they can be very useful. Take mules, for example, the offspring of a male donkey and a female horse. They’re bigger than donkeys and hardier than hor... Read More
