Impressive photos and illustrations - as befitting a coffee-table (or waiting room) book - the sections are concise and well organized as well.
Unfortunately, while there are some interesting developmental facts within, they are presented alongside a number of contentious, dubious, and unsupported theories and assertions (all without citation). These range from the benign/risible to the patently illogical/offensive; for example:
1. Mothers evolved to distinguish the cry of their own baby so they wouldn't wake up when other babies cried in the village huts.
2. Mothers favor resting their baby on their left breast where the baby will better hear the mother's voice in their left ear which is linked to the right hemisphere of the brain, which is responsible for processing the emotional quality of sounds.
3. Dizygotic twins are more likely to be conceived from an intensely emotional or violent coupling, such as rape.
4. Only a diet that includes animal proteins can supply the human digestive system with the ideal amino-acid balance.
5. Males evolved to be hunters, explaining their inborn tendencies towards emotional suppression, and increased strength/agility/spacial awareness compared to females, who evolved to be multi-taskers, explaining their inborn tendencies towards sociability, emotional intelligence, caregiving, etc.
Had I been familiar with Desmond Morris prior to picking this up I would have left it on the shelf as I see he has made a career "popularizing science," by erroneously extrapolating the findings of his specialty (zoology circa the early 1960s) to a number of other disciplines (anthropology, psychology, cognitive neuroscience, etc.) while ignoring contradictory evidence emerging from within those specialties.
