Inside Nature’s Giants uses dissection, CGI and wildlife photography to show, from the inside out, how millions of years of evolution have enabled four species to thrive in their environmental niches. In this edition, with veterinary scientist Mark Evans as guide, a team of experts investigate the giraffe. Evolutionary biologist Professor Richard Dawkins reveals how the anatomy of the world’s tallest animal provides some of the best arguments in favour of Darwinian natural selection. And as the dissection team pieces together the remarkable evolutionary story of the giraffe, biologist Simon Watt observes them in the field as they eat, forage and fight.
