Title: Very interesting, but an author who belabors her points.
Review: There is a lot of very interesting material, reasonably well organized. Rogers, a researcher herself, seems to be aware of all the pertinent research, not only in animal intelligence, but in all the related areas: neuro-biology, anthropology, child developmental psychology and evolution. She takes great pride in her objectivity and care as a scientist, without being afraid to express personal beliefs, clearly labeled. Her style leaves something to be desired. She fears the reader will "unscientifically" draw unsubstantiated conclusions, and addresses this by constant repetition of more or less the same warnings. Surprisingly, a number of birds seem to be as intelligent as primates, and even domesticated chickens are fairly intelligent, not withstanding that birds don't have a neo-cortex, and must keep brain size small because of weight considerations.
