Episode 32A: Canids

We're all familiar with canines (dogs, wolves, jackals, foxs, etc), but these are just only one of three sub-families of the larger canid family to survive to the present day. There were also the Hesperocyoninae and Borophaginae, but what did these other canids look like and why did they go extinct? The canid family also falls within the larger suborder Caniformia which includes skunks, bears and seals, but how are all these related? We've therefore quite a lot of history of the group to cover before we eventually see Canis lupus familiaris become man's best friend. To talk us through their evolution is Dr Xiaoming Wang of the Natural History Museum, Los Angeles.
