Does this frog look a little scary? It looks that way on purpose. This frog is a poisonous dart frog. They live in Central and South America. Why do you think the frog is so brightly colored? Why do you think the frog is poisonous? Why does the frog only live in warmer climates? There are also many different types of poisonous dart frogs. Some are red, some blue, some yellow. So why is there such a great diversity of poisonous dart frogs?
Scientists who study evolution are concerned with these types of questions, but they ask them about all of the species on the planet. Why are there millions of different types of species? Why are some small, some large, some furry, and some covered in feathers? These questions will be explored as we learn about the theory of evolution.
