Nature Tracks - Toad in the Hole

Frogs and their amphibious relatives represent and evolutionary landmark, both literally and figuratively. Some three to four hundred years ago these intrepid creatures took their first pioneering hops, out of the sea and onto terra firma. Thus, the stage we set for a new era in evolution and ultimately all land animals, including man, have them to thank. This episode of 'On Track' takes a look at the descendants of these first colonists.
