I decided to look at Mammalia branch.This branch includes animals like humans, dogs, cats and whales. I think its really cool to see how all the different animals are actually related when you look at their family history. The way the tree is organized makes a lot of sense to me. It is like a giant map that shows living that is connected.It makes it easier to learn and understand.
