Elephant - S1.E1 - Inside Nature's Giants
This programme looks at how evolution has overcome the challenges of being as big as an elephant.
Elephants feed on plants with very little nutritional value for 18 hours a day, so evolution has given them vast intestines as well as huge teeth and jaw muscles - and an equally gigantic head. But this produces another problem: how to reach food on the ground.
The solution is the most versatile limb on the planet - the trunk. Capable of everything from picking up berries to ripping a tree from the ground, the trunk is a wonder of evolution. It's a Just So Story for the Darwinian age.
