Sir David Attenborough chats with Greg

Sir David Attenborough chats with Greg about his life-long love of natural history.

He also talks about the second series of Natural Curiosities. The first programme, called Virgin Births, includes both greenfly and comodo dragons.

Sir David tells Greg why a female Hyena appears to have male naughty bits. You have GOT to listen to this! He also picks his all time favorite adventure and talks about naming new species. Will Greg's proposed extra programme make the grade?
