Why men have nipples, and other 'Human Errors'

The new book “Human Errors” looks at flaws in our bodies, why we have them, and what’s possibly in store for our future. We look at why humans have more colds than most other animals, how we can’t produce essential vitamins and minerals like other animals, why men have nipples, and more.
