Of all the scientific disciplines, underwater archaeology may be one of the most fascinating. These researchers examine artifacts our ancestors left behind before global sea level rose and covered them. A newly discovered monolith—a gigantic rock placed in what is today the Mediterranean Sea—confronts a few evolution-based errors about human origins.

As weird as it may sound, some snakes had legs. Fossils reveal little legs on ancient snakes that have apparently been extinct for some time. Yet, those had only hind legs. Now, in the journal Science researchers describe a new fossil with four limbs. They suggest that this new fossil illustrates how legged snakes evolved from legged lizards. Is this accurate?

The Jurassic World movie, though thrilling to watch, comes packed with fictional ideas like de-extinction, designer creatures, and iron somehow preserving dinosaur DNA indefinitely. But how would the world respond if live dinosaurs were verified to scientists' satisfaction?
