Via New Scientist:

It's relatively well understood how the first fish began to move on landMovie Camera and breathe in air, but how vertebrates switched from feeding via suction to evolve a tongue remains unclear. Seeking an answer, Krijn Michel at the University of Antwerp in Belgium and his colleagues looked to the mudskipper.

They captured high-speed X-ray footage of Atlantic mudskippers (Periophthalmus barbarus) out of water pouncing and chowing down on pieces of brown shrimp. The move takes less than half a second but, slowed down 50 times, they spotted that mudskippers carry water in their mouths, which they spit forwards to help grab food then suck it back to swallow, mimicking the action of a tongue.

You've probably learned about vestigial organs in Biology class by now. There are a lot of things that aren't important to humans any more but we've still held onto them in some way. If you've ever seen someone wiggle their ears, it's obvious. 

This video shows some of those unnecessary parts and why we used to have them. It also goes into detail about the way that some humans have actually lost those extra pieces. 



That's evolution at work.

Bill Nye, the knower of all things, is out with a new video in which he encourages creationist parents to embrace their "crazy, untenable, inconsistent" world view -- just so long as they don't force it on their offspring:

If you want to deny evolution and live in your world, in your world that's completely inconsistent with everything we observe in the universe, that's fine, but don't make your kids do it because we need them.

We need scientifically literate voters and taxpayers for the future. We need people that can... we need engineers that can build stuff, solve problems.

It gets especially good right around the time humans evolve into "fat" a la Wall.E.
