Think about it
Three new books offer scientific insights into how various animals (including humans) think.
Animal Wise: The Thoughts and Emotions of Our Fellow Creatures (Crown) by Virginia Morell looks at chimps that play computer games, dogs with 1,000-word vocabularies and laughing rats.
Cat Sense: How the New Feline Science Can Make You a Better Friend to Your Pet (Basic Books) by John Bradshaw reveals why cats purr, why they often don't like other cats and why that dead mouse Fluffy brings you doesn't mean what you think.
The Rational Animal: How Evolution Made Us Smarter Than We Think (Basic Books) by Douglas Kenrick and Vladas Griskevicius explores why what often seems like irrational, biased, hypocritical or self-defeating human behavior may actually make sense in terms of deep-seated evolutionary goals.
