A tree of life is like a giant family tree - it shows how all life forms are related to each other. It can show us who our closest cousins are and reveal our distant relatives. So how far back can we look in this family tree? To find out when we split from other mammals? From fish, worms, mushrooms, plants, pond scum or bacteria?
The basic shape of the tree of life changes as we discover more about the world around us and about its natural history. Meet a Museum scientist who works on this great map of life and find out the scientific controversy it can cause.
