What is Evolution?

Excellent video from Stated Clearly explaining just what evolution is … using great illustrations from Rosemary Mosco’s Bird and Moon comics.

This is a great video to share with friends/enemies/confused relatives that might have trouble accepting evolution and how simple it can be to understand. 

I’d like to add one thing to this video. Single amoebas, pairs of parents and a few children are used in these evolution illustrations to simplify the concept of evolution, but it’s important to remember that evolution is something that happens to populations, not individuals. The changes within a generation are random. It’s only after those changes have been passed on for several generations that a survival advantage or disadvantage (followed by either more or less individuals carrying the trait) occurs. That’s where evolution happens, it’s not in the change itself. And sometimes even harmful traits can become frequent in a population, like we see in diseases that are prevalent among isolated ethnic groups.

Bonus: I’d also recommend Understanding Evolution’s “Common Misconceptions” FAQ for those who want to dig deeper.
