This paper presents 13 hypotheses regarding the specific behavioral abilities that emerged at key milestones during the 600-million-year phylogenetic history from early bilaterians to extant humans. The behavioral, intellectual, and cognitive faculties of humans are complex and varied: we have abilities as diverse as map-based navigation, theory of mind, counterfactual learning, episodic memory, and language. But these faculties, which emerge from the complex human brain, are likely to have evolved from simpler prototypes in the simpler brains of our ancestors. Understanding the order in which behavioral abilities evolved can shed light on how and why our brains evolved. To propose these hypotheses, I review the available data from comparative psychology and evolutionary neuroscience.

See Vértes and Seidlitz (doi:10.1093/brain/awz353) for a scientific commentary on this article. Is schizophrenia a by-product of human brain evolution? By comparing the human and chimpanzee connectomes, van den Heuvel et al. demonstrate that connections unique to the human brain show greater involvement in schizophrenia pathology. Modifications in service of higher-order brain functions may have rendered the brain more vulnerable to dysfunction.

The Brain

This introductory chapter begins by providing an overview of the power of the human brain, which is displayed in the wonders of modern civilization. Despite the human brain’s capacity for such intellectual and technological feats, we still know astonishingly little about how it achieves them. This deficit in understanding is a problem not only because it means we lack basic knowledge of the biological factors that underlie our human uniqueness, but also because, for all its amazing capabilities, the human mind seems particularly prone to dysfunction. Still, some would argue there is good reason to be optimistic about the prospect of developing new and better treatments for mental disorders in the not-so-distant future. Such optimism is based on the increasing potential to study how the brain works in various important new ways thanks to recent technological innovations. The chapter then considers two overly polarised views of the human mind. Ultimately, this book argues that society radically restructures the human brain within an individual person’s lifetime, and that it has also played a central role in the past history of our species, by shaping brain evolution.
