A Moment of Science
The counting system of native Greenlanders not only uses all ten fingers, but all ten toes as well!
A Moment Of Science revisits the science of hands and feet that wrinkle when wet.
Why not 5 or 15? Why is 10 the magic number when it comes to fingers and toes?
Before about 360 million years ago, no vertebrates had limbs. They all shared the same fish-like body shape. But around that time something exciting happened.
