It's actually fairly amusing that on the same day of discussion how science labs could or couldn't disprove god's existence that these canadians have studied lungfish and watched them adapt to walk on land more efficiently.

Silly bait aside <.<

Here are some articles.

The tl;dr for the lazy or those who dun speek biology.

The fish not only adapted by walking in a different manner but they displayed plasticity (Ability to change) in their 'shoulder' joints in a similar manner to the first fish that walked on land millions of years ago.

It's pretty interesting stuff.
