Which part of the human body evolved most recently?

Asked by: Luca Blackwell

Evolution doesn’t just hand out useful traits such as opposable thumbs or colour vision like lottery prizes. Natural selection is constantly tinkering, and no part of our body is more ‘recent’ than another. But some are changing faster.

One of the fastest movers is the human jaw, which has been steadily shrinking over the last 10,000 years, as the invention of agriculture and cooking gave us softer foods that need less chewing.
