Really I think the book deserves an A, but I'm withholding that grade in favor of a B because I don't think it's quite as accessible to a non-specialist audience as the book was hoping to be. I'd definitely, definitely use it for a class or a book group, though! Aug 27, Jennifer rated it liked it. This is how engrained a male perspective has been in our western medical history. Jun 27, Rebecca rated it really liked it. Excellent read. Everyone should read this book, but of course women especially.

A useful metaphor to an extent, but when you consider the body as an evolved form that has been shaped by forces favoring reproduction for millions of years, it is more helpful to look at the body as a bundle of compromises.

Compromises that have favored reproduction that's how natural selection works , maybe even at the cost of long-term health and longevity. An evolutionary approach to health addresses the mismatch between our evolved bodies and our physical lifestyles. Because cultural evolution has outpaced biological evolution think of game-changers like agriculture, birth control, modern medicine, etc.
This well-researched book covers all the major phases in a woman's life with regard to her one evolved purpose: reproduction. This is not to argue that reproduction in the most important function of a woman's identity, but that her health cannot be understood outside of the way her body has evolved. This book also inadvertently helped me understand the evolutionary approach to the paleo diet as well though the anthropologist author does not address this in the book.
The idea is not so much to mimic paleolithic living as it is to recognize that we are already living in paleolithic bodies! The argument is not one of complete biological determism of which I am a staunch opponent because it's very premise is that we live in a unique environment created by culture, and this is what creates a challenge for our health.
Adding Trevathan's view of the body as a bundle of compromises shaped for reproduction is an often-missing piece to the dietary puzzle, and I have much more exploring to do!

Wider pelves may also increase the risk of injury, either through increasing the likelihood of pelvic prolapse 47 or by increasing mediolateral stresses on the knees and ankles These scenarios would suggest an OD-like mechanism acting on pelvic morphology secondarily to the metabolic limits on neonatal body and brain size. A third possibility is that the present level of difficulty and danger in childbirth is a relatively recent phenomenon brought on by an increase in maternal energy consumption In this scenario, recent changes in the diet have increased energy availability during gestation, leading to larger neonates, but selection has not had sufficient time or reason to accommodate the female pelvis to this recent dietary change.
Finally, a fourth possibility, originally proposed by Portmann 5 , is that the timing of human birth and degree of neonatal brain development optimizes cognitive and motor neuronal development Additional work is needed to determine whether these factors, or others, might help to explain the difficulty of birth in modern human populations. Although the development of neural circuitry, pelvic size, fetal growth rates, and other factors may be involved in the evolution of gestation length, the evidence we present here supports an energetic explanation, based on mammalian physiological constraints, for the timing of human birth.
Under the EGG hypothesis, if the human reproductive system poses a dilemma between competing needs, then fetal energy needs and maternal energy supply are the competitors, rather than encephalization and bipedalism. Thus, human neonatal altriciality is better described as prolongation of fetal brain maturation and growth irrespective of parturition 5. With a better understanding of the energetic constraints on gestation and fetal growth and a stronger grasp of all of the factors that determine human birth timing, there is greater potential to explain the evolution of the extended human childhood and to understand its biological, behavioral, and cultural consequences.
