It’s easy to see ourselves as separate from the animal kingdom, but Adam Rutherford, author of “Humanimal: How Homo sapiens Became Nature’s Most Paradoxical Creature - A New Evolutionary History,” believes that we aren’t as different as we might think. Fashion design, interacting with fire, and making multi-step plans all seem like qualities that are unique to humans. But according to Rutherford, species across the animal kingdom - from crabs to birds of prey - exhibit many of these complex behaviors too.
