Summary

The evolution of horses is a classic story, first because it is a beautiful example of evolution in the fossil record, and second because of how our scientific perspective of this story has shifted over the years. From the tiny forest-dwellers of the Eocene, barely recognizable as horse-relatives, to the mighty domesticated animals we know today, we’ll unpack what we know – and what we thought we knew – about horse evolution. In the news: dinosaur teeth, alligator tools, ancient embryos, and dinosaur heads.

0:32.2	This has been a popular requested topic, and I've been looking forward to it.
0:37.0	Horse evolution is a cool
0:38.4	evolutionary topic and a cool event in fossil history. Not only are there lots of cool things to say
0:45.5	about fossil horses, but the topic of horse evolution has been in many ways pivotal in our
0:51.8	understandings of evolution and interpreting the fossil record and
0:57.0	Yeah, it's a textbook case.
0:59.0	Literally.
1:00.0	Yeah, yeah, it is absolutely.
1:01.0	Like, literally this is a textbook case.

1:44.0	Yes.
