I've heard that fish turned to mammals because of evolution. And I wanna be a mammal!
Hey you! I need you to help me. How do you turn into a mammal?
No, no, you've got it wrong. Evolution happened slowly, using natural selection. The fish that could live in more shallow water had offspring, which could live in even more shallow water. And so on. You can't just become a mammal.
Ack, help, I can't breathe!
Whatever, I'm still trying >:(
Extinction is when all the animals in a species die out.
Ha, it's weird that you still aren't extinct.
Well. I'm leaving.
Wait, what's natural selection?
Natural selection is how evolution usually happens. There is competion in nature, and the animals that survive have offspring with similar characteristics. So the animal with adaptations that help the animals get passed down to their offspring
