Upon becoming pregnant with her second child, Dr. Alice Roberts wanted to know what made her child different from the babies of other species. She explores the question of what makes us human in this DVD. Dr. Roberts starts by comparing her offspring to the biology of its closest genetic relative, the chimpanzee. Although we share 99% of our DNA with this species, there are things about our biology that separate us.
After this, Dr. Roberts looks at a number of other factors that make our species uniquely human. The DVD includes interviews with geneticists, philosophers, biologists, and much more.
