Secrets of Bones Episode 1 of 6

Evolutionary biologist and master skeleton builder Ben Garrod begins a six-part journey to discover how bones have enabled vertebrates to colonise and dominate practically every habitat on Earth.

Ben shows us what bone is constructed from and how it can support animals that are both minuscule - a frog just a few millimetres long - and massive - the blue whale, two hundred million times bigger.
