Our sensitive teeth originally evolved from the "body armor" of extinct fish that lived 465 million years ago, scientists say. In a new study, the researchers showed how sensory tissue discovered on ...

Researchers have found that chunks of "flipped" DNA can help fish quickly adapt to new habitats and evolve into new species, acting as evolutionary "superchargers." Why are there so many different ...

The next time you wince from an ice-cold drink or a too-hot slice of pizza, blame your ancestors. Specifically, the armor-plated fish that swam Earth’s oceans over 460 million years ago. A new study ...

You may never have wondered why you have five fingers at the end of each arm (or why you have fingers at all, for that matter) but the answer is surprisingly interesting and a little cheeky. A recent ...
