While we have many continuities with our primate cousins, and with the other inhabitants of the living realm more broadly, it is also true that people are pretty special. We do all manner of th for example, some of us wear clothes, vote in elections, give hi-fives, or write book reviews. It is also true that we, as a species, have been very prosperous we inhabit a huge range of different habitats, our population has exploded and we are able to dominate and control most of the creatures who attempt to share our habitats with us. In The Secret of our Success (henceforth SOOS) Joseph Henrich argues that these properties are connected that those idiosyncrasies of our behaviour that we tend to term for the success our species enjoys. We think this a most reasonable ss, slowness and dullness of senses, we have been able to out-compete so many much stronger, faster and physically less vulnerable animals. A solitary, unequipped and uneducated human is generally a fairly unimpressive specimen. But allow her access to her culture and all that it can do and she might move mountains.The devil is in the detail of this appealing thesis, however. W it, and what is the nature of its connection to our success? SOOS presents as a trade book, so it is packed with colourful examples, personal observations, anecdotes, and connections with current events; the language is racy and informal. This makes it a lively, engaging read in which the author emerges in a good way as a swashbuckling anthropologist. Navigating the high seas of field work, and thrusting the sword of laboratory intervention, Henrich is trying to bring it all together into a new, coherent picture of human origins. But, perhaps inevitably, the details and the logical structure are somewhat difficult to divine. SOOS succeeds in giving an exciting glimpse of the rapidly expanding academic literature on cultural evolution and will be sure to attract new enthusiasts to the topic. A dryer text may have served better as a contribution to the literature, however. We accordingly focus, in this review, on discussing how we would like to see the field develop, and what we wish the book had spelt out. First, we offer the following summary of the main ideas on display.
SummaryHenrich claims that human beings are unique different from all other animals in that they engage in a process of Cumulative Cultural Evolution (hereafter CCE). It is the technological and cognitive products of CCE, he argues, that explain our extraordinary success. Henrich allows that some nonhuman animals may be capable of some cultural evolution, but he insists that only humans have become able to sustain cultural evolution in its cumulative form.
