No doubt you’ve all seen some of the hype surrounding the new book, Big Brain: The Origins and Future of Human Intelligence by Gary Lynch and Richard Granger. The book argues that a long-extinct hominin species, the “Boskops”, were much smarter then we are:

Our big brains, our language ability, and our intelligence make us uniquely human. But barely 10,000 years ago–a mere blip in evolutionary time–human-like creatures called “Boskops” flourished in South Africa. They possessed extraordinary features: forebrains roughly 50% larger than ours, and estimated IQs to match–far surpassing our own. Many of these huge fossil skulls have been discovered over the last century, but most of us have never heard of this scientific marvel.

Prominent neuroscientists Gary Lynch and Richard Granger compare the contents of the Boskop brain and our own brains today, and arrive at startling conclusions about our intelligence and creativity. Connecting cutting-edge theories of genetics, evolution, language, memory, learning, and intelligence, Lynch and Granger show the implications of large brains on a broad array of fields, from the current state of the art in Alzheimer’s and other brain disorders, to new advances in brain-based robots that see and converse with us, and the means by which neural prosthetics– replacement parts for the brain–are being designed and tested. The authors demystify the complexities of our brains in this fascinating and accessible book, and give us tantalizing insights into our humanity–its past, and its future.

It seems to be getting glowing reviews all over the place - Cognitive Neuroscientist Michael Gazzaniga says it’s “like mixing gas with fire. In this book there are big, explosive ideas by two ingenious brain scientists”.  William Calvin reviews it in New Scientist (”I’ve been waiting for someone to write this book for years“). Discover Magazine tells us that the Boskops probably had “an internal mental life literally beyond anything we can imagine“.

….and unsurprisingly it’s all crap. John Hawks discusses the anthropological evidence for these Boskops and, well, it ain’t that good:

This category became untenable as further information about the archaeology of South Africa came to light. Ronald Singer (1958) reviewed the “Boskop race” evidence as it existed by the 1950’s. He concluded that there was no reason to maintain that any “big-headed, small-faced group” had existed in prehistory, separate from the current biological variability of “Bushman, Hottentot and Negro.” But that view is unsupportable — in fact, what happened is that a small set of large crania were taken from a much larger sample of varied crania, and given the name, “Boskopoid.” This selection was initially done almost without any regard for archaeological or cultural associations — any old, large skull was a “Boskop”. Later, when a more systematic inventory of archaeological associations was entered into evidence, it became clear that the “Boskop race” was entirely a figment of anthropologists’ imaginations.
