“For many Westerners, “it’s natural” seems to mean “it’s good.” This view is wrong and comes from shopping in supermarkets and living in landscaped environments. Plants evolved toxins to deter animals, fungi, and bacteria from eating them. The list of “natural” foods that need processing to detoxify them goes on and on. Early potatoes were toxic, and the Andean peoples ate clay to neutralize the toxin. Even beans can be toxic without processing. In California, many hunter-gatherer populations relied on acorns, which, similar to manioc, require a labor intensive, multiday leaching process. Many small-scale societies have similarly exploited hardy, tropical plants called cycads for food. But cycads contain a nerve toxin. If not properly processed, they can cause neurological symptoms, paralysis, and death. Numerous societies, including hunter-gatherers, have culturally evolved an immense range of detoxification techniques for cycads. By contrast with our species, other animals have far superior abilities to detoxify plants. Humans, however, lost these genetic adaptations and evolved a dependence on cultural know-how, just to eat.”

“The case I’ve presented in this book suggests that humans are undergoing what biologists call a major transition. Such transitions occur when less complex forms of life combine in some way to give rise to more complex forms. Examples include the transition from independently replicating molecules to replicating packages called chromosomes or, the transition from different kinds of simple cells to more complex cells in which these once-distinct simple cell types came to perform critical functions and become entirely mutually interdependent, such as the nucleus and mitochondria in our own cells. Our species’ dependence on cumulative culture for survival, on living in cooperative groups, on alloparenting and a division of labor and information, and on our communicative repertoires mean that humans have begun to satisfy all the requirements for a major biological transition. Thus, we are literally the beginnings of a new kind of animal.1 By contrast, the wrong way to understand humans is to think that we are just a really smart, though somewhat less hairy, chimpanzee. This view is surprisingly common. Understanding how this major transition is occurring alters how we think about the origins of our species, about the reasons for our immense ecological success, and about the uniqueness of our place in nature. The insights generated alter our understandings of intelligence, faith, innovation, intergroup competition, cooperation, institutions, rituals, and the psychological differences between populations. Recognizing that we are a cultural species means that, even in the short run (when genes don’t have enough time to change), institutions, technologies, and languages are coevolving with psychological biases, cognitive abilities, emotional responses, and preferences. In the longer run, genes are evolving to adapt to these culturally constructed worlds, and this has been, and is now, the primary driver of human genetic evolution. Figure 17.1.”
