Extinct Species for Students | Science Guide

🌟 Introduction

The word extinct means that a type of plant, animal, or other living thing has completely disappeared from Earth. Once a species is extinct, no members are left alive anywhere in the world. Dinosaurs are the most famous example of extinction, but many other animals and plants have vanished too, such as the dodo bird and the saber-toothed cat. Extinction can happen naturally over millions of years or suddenly due to changes in climate, loss of habitat, or human activity. Learning about extinction helps us protect species that are still alive today.
