First up on this week’s show, what killed off North America’s megafauna, such as dire wolves and saber-toothed cats?

They discuss how the La Brea Tar Pits are helping researchers figure this out. Read the related Science paper.

Next up, do languages get less complex when spoken in multilingual societies? Olena Shcherbakova, a doctoral researcher at the Max Planck Institute for Evolutionary Anthropology, joins Sarah with a broad look at how the complexity of languages changes under different social and linguistic environments.
