Affable host and astrophysicist Neil deGrasse Tyson guides "Nova" fans on a tour of what science has revealed so far about the origins of human life in this episode that focuses on life forms created billions of years ago. The program explores the birth of our solar system as well as the invaluable knowledge about human evolution that scientists have gained by studying another species altogether: head lice.
