I recently read Animal Wise: How We Know Animals Think and Feel (2013) by Virginia Morell, correspondent for Science and contributor to National Geographic, Smithsonian, and other publications. She’s author of several books including Wildlife Wars (2001), which she co-authored with Richard Leakey.
Morell takes us on a tour of current research into the minds of animals, starting with ants and working up through various species to our primate relatives. Dear to my heart, she reserves the last chapter for our best friends, dogs.
I found it a wonderful exploration with some real eye-openers.
