Nothing About Dire Wolves Was Normal... Here's Why?

Nothing About Dire Wolves Was Normal... Here's Why? The dire wolf looked like a wolf, hunted like a wolf, and was even built like one. But when scientists sequenced its ancient DNA, they found a story its bones could never tell. In this video, we look at what the dire wolf’s fossils, teeth, and genes reveal about it. We cover how it lived alongside Smilodon in Ice Age Los Angeles, why so many Ice Age predators had broken teeth, and what the genomes say about where it came from. We also cover how its lineage disappeared at the end of the Ice Age. Sources: Along the way, we see why a familiar appearance can hide a very different evolutionary history. Perri et al.
