From The Atlantic: "In the past 30 years, research has explored the distinctive ways in which children as well as animals think, and the discoveries deal the coup de grâce to the (so-called) ladder of nature. The primatologist Frans de Waal has been at the forefront of the animal research, and in 'Are We Smart Enough to Know How Smart Animals Are?,' he makes a passionate and convincing case for the sophistication of nonhuman minds. … De Waal notes that there isn't even a good general name for the new field of research. Animal cognition ignores the fact that humans are animals too. De Waal argues for evolutionary cognition instead."
