Homebody Bees and Bullying Chimps
As scientists learn how our personalities stem not only from nurture but from nature, including differences in brain structure and function, the question arises: Do other species have personalities, too?

He takes us on a photographic tour of species as different as honeybees and silver foxes and explains what scientists are discovering about how subtle differences in the brain may have major effects on personality.
