New Evidence Suggests That Human Limbs Evolved from Shark Gills

First off, credit goes where credit is due, that is great research from the team at Cambridge. If proven further, that evidence is sure to change every evolution course taught in the future.

For me though, that headline just killed the story. Come on Gizmodo. Find someone else for the evolution assignments.

I know it's a deep subject to wrap your head around, but you just can't say that human gills evolved from shark limbs. What should have been squeezed into the headline is this: our ancestors' limbs evolved from what were once the gills of an ancient species -- that eventually evolved into a thousand other species, but who most closely resembles our modern sharks.

"New evidence suggests that human limbs evolved from our ancestors' gills" is just as evocative, and has the nice bonus of not being a blatant lie.
