Expert primatologist Frans de Waal has been working with chimpanzees and bonobos, our closest evolutionary and genetic relatives, for about 40 years.
In his new book, "The Bonobo And The Atheist" (W. W. Norton & Company, Inc, 2013), he argues that our morality — how we empathize with others and have a desire to be fair to others — isn't based in our culture or our religion, but instead comes from the way we've evolved over time.
He says that like humans, our primate relatives also show the ability to care for others around them. He visited the office to explain to us the similarities in morality between humans and chimpanzees and bonobos.
