Thanks for listening to Origin Stories! We are on hiatus as we work on new episodes. Our new season will launch in August, and we can't wait to share more stories about how we became human.

In On the Origin of Species, Charles Darwin used a sketch of a tree of life to help describe his theory of evolution. In this metaphor, the branches of the tree represent the relationships between all living and extinct creatures. Humans, like all living creatures, are on the surface of the tree, and all extinct creatures are within the tree.


In this episode we talk with Dr. Bernard Wood who studies our part of the tree of life. Wood tells us how scientists figure out which fossil creatures are our ancestors and which were just our close relatives.
