Summary

When vertebrates first moved onto land, they gave rise to a variety of amphibious tetrapods. The most diverse and successful of these were temnospondyls, which were some of the most important species in early land and freshwater environments. This episode, we’ll explore temnospondyls’ evolutionary history, their ecological variety, and their mysterious connection to modern amphibians. In the news: domesticating dogs, early birds, color evolution, and changing seeds.

0:34.1	Yeah.
0:44.5	Temnospondles are the famous group of ancient early tetrapods or amphibians in a little bit of air quotes.
0:57.9	Temnospondals were one of the most important groups of life on land in the early history of land vertebrates and also continuing into the early history of things like dinosaurs in the early history of land vertebrates and also continuing into the early history of things like dinosaurs and the age of reptiles.
