The new book, Paleofantasy: What Evolution Really Tells Us about Sex, Diet, and How We Live, is billed as an "exposé of pseudoscientific myths about our evolutionary past and how we should live today." It was written by Marlene Zuk, a professor of ecology, evolution, and behavior at the University of Minnesota.
Many people who follow the paleo regimen have reviewed the book on their blogs, but my favorite review so far is by Mark Sisson, author of The Primal Blueprint (my favorite paleo book). He says the problem with the book is that no one who follows paleo believes any of the straw man premises she sets up. In other words, Zuk's idea of Paleo is the real paleofantasy and her arguments against her own straw man version of paleo were explored and accepted years ago by the Paleo community.
After reading the book, John Durant tweeted “Paleofantasy shouldn’t have been a book in 2013, it should have been a blog post in 2010,” and that’s as good a description as I can think of.
It’s all very uncontroversial:
There is no one paleo diet.
Who’s saying that? Humans have spanned the globe for millennia, surviving and even thriving in environments ranging from tropical to temperate, from arctic to near-aquatic, all the while subsisting on the wild foods available to those regions. Same basic diet of animals and plants, different configurations.
Evolution doesn’t just stop and humans didn’t just reach a state of perfect adaptation back before agriculture from which we’ve never progressed.
Sure. I talked about how we’re still “evolving” last year, even mentioning Zuk’s favorite topics – lactase persistence (35% worldwide, which is far from 100%) and amylase production. She discusses a few more recent changes, like malaria resistance, adaptation to high altitude, and earwax differentiation, but that’s it. If she wanted to, I’m sure she “could keep adding to the list” and mount an overwhelming case for widespread genetic adaptations to grain consumption, chronic stress tolerance, and sedentary living, but she’s saving up material for the next book. Or something. Either way, I’m not very convinced by her “list” of rapid evolutionary changes, especially considering most of them have little to do with the mismatches we discuss in this community and none of them are even present in a majority of humans.
Zuk is also quick to misrepresent “our” arguments so she can swoop in and take the sensible position – positions the ancestral health community has long occupied!
Is It All Just a “Paleofantasy”
