That's One Small Hop For Fish

One giant leap for evolution.

Alice Gibb from Northern Arizona University and colleagues discovered 6 unrelated species of fish that have evolved the strange ability to jump:

Researchers discovered that at least six different types of fish are able to launch themselves into the air from a solid surface.

The team said this was an evolutionary snapshot of the transition from living in water to inhabiting land. [...]

It suggests that, rather than a rare adaptation that evolved in a select few species, the ability to leap on land is common among bony fishes. So many more of their ancient aquatic relatives might have invaded the land than had previously been thought.
