To start today’s article, here are some quick facts about our planet. Earth has been around for over 4 billion years, and it’s hosted around five billion different species of animals, including humans. Almost every species that’s ever lived–99.9% of them, to be exact–have already gone extinct, but that still leaves 8.7 MILLION different species alive right now.
With such a variety of creatures living on the blue planet, you’d think Earth boasts incredible biodiversity. And it does…to an extent.
Because it turns out nature recycles the same designs over and over again. Instead of coming up with a brand new animal each time one evolves, sometimes nature just goes, “Eh, this one’s going to look like a human penis.”
OK, I’ll be honest…those animal facts above don’t really have anything to do with this article, but I figured you should get something educational out of this.
