Okay, kiddo. Do you know what extinction means? It's when a type of animal or plant can no longer be found alive, kind of like when your goldfish dies. Do you remember the dinosaurs? They all went extinct a long, long time ago because of something called an asteroid impact. But did you know that there was another big extinction event that happened a lot more recently, about 11,000 years ago?
This is called the quaternary extinction event, and it's when a lot of big animals like mammoths, giant sloths, and saber-toothed tigers disappeared from the world. Scientists think that a lot of different things caused this extinction, like climate change, humans hunting too much, and changes in the environment.
Imagine if all the big animals in the world today like elephants, lions, and bears suddenly all disappeared. It would be really sad, right? That's what happened during the quaternary extinction event, and scientists are still trying to figure out exactly why it happened and what it can teach us about taking care of the animals we have left today.
