Discovery: Wild Inside: The Red Kangaroo

Professor Ben Garrod, evolutionary biologist from the University of East Anglia, and expert veterinary surgeon Dr Jess French perform post-mortems on wild animals, aiming to unravel the creatures' intricate internal complexity. Here they learn about the anatomy of the largest marsupial, the red kangaroo. Despite the immense heat and lack of water, these marsupials dominate Australia, with their evolutionary history driving them to success - from the powerful legs which allow them to hop up to 40km an hour to an unexpected reproductive system that keeps their populations plentiful
