Languages drift, adapt and evolve much like living species. In this wide-ranging conversation, evolutionary biologist Richard Dawkins and linguist John McWhorter trace the parallels between biology and speech, from random mutations to cultural selection. They show how both genes ... Show More

Melvyn Bragg and guests discuss the evolution of lungs and of the first breaths, which can be traced back 400 million years to when animal life spread from rock pools and swamps onto land, as some fish found an evolutionary advantage in getting their oxygen from air rather than w ... Show More
