What do we have in common with fish, besides being vertebrates? The types of joints we (and most vertebrates) share most likely originated from the same common ancestor. But it’s not a feature that we ...

Yara Haridy, an evolutionary biologist at the University of Chicago, likes to stun people by telling them that our skeletons evolved from a jawless fish. "Much of what we have today has been around ...
