There's been a long-standing debate about whether or not the key features that define placental mammals like ourselves emerged in our ancestors before or after the extinction event that wiped out the dinosaurs.

    This is wildly clickbaity. We’ve known forever that mammals existed alongside dinosaurs. Calling it a “human ancestor” is a bit misleading when really it’s more like a rat/cat/dog than a hominid of any kind.
