Darwin's Finches and Evolution (Classroom Series)

She's got a nice one.

True.

What about his?

Interesting.

Okay, okay.

Can we stop looking at everyone's noses and get back to the finch's beaks for now?

So, on the Galapagos, Darwin found that finch beaks and their feet varied

island by island, proving evolution because nature was selecting the fittest birds to survive and reproduce.

Uh, I don't think that that proves evolution.

It just simply shows that the finch's beaks were adapting to their food sources on that specific island.

There was a 2017 article in the science journal BMC Evolutionary Biology, and they found they weren't actually

mutating and evolving by mutations and natural selection.

Instead, it was epigenetic changes, which is special coding that allows the animals to track and adapt to their environments

without changing the DNA, and it happens in just one generation.

So, it was never evolution.

Really cool.
