A “weird” species of “walking” fish is helping shed light on how humans evolved to stand upright millions of years ago, according to scientists.

The sea robin, a bony fish that lives at the bottom of the ocean, has six leg-like structures that it uses to scurry across the sea floor, and sometimes dig for prey.
