Today Tom is Under the Microscope with Dr. Kevin Arbuckle, an evolutionary biologist and lecturer at Swansea University. Have you ever wondered how we classify organisms, how we can use the genes of organisms to estimate the states of their ancestors and the applications that has for todays world? Like predicting the existence of new human species for them only to be discovered shortly after! Music by: Joakim Karud - https://soundcloud.com/joakimkarud.
