No Recent Human Evolution

False Assumption: The human mind is adapted to the conditions of 10,000 years ago and has not changed since.

Careers were damaged, research programs chilled, and whole lines of inquiry were treated as radioactive under the assumption that the human mind was basically a Pleistocene relic, adapted to life before agriculture and unchanged in any important way over the last 10,000 years. Critics say that taboo helped leave policy and scholarship talking past stubborn differences in violence, social trust, and institutional fit, while scientists who probed recent selection on behavior risked accusations of racism and professional ruin. The assumption took hold after World War II for reasons that were not frivolous: biology had been abused in the service of atrocity, and early evolutionary psychology found it parsimonious to speak of a universal human nature shaped in the ancestral environment. In that frame, agriculture and states were too recent to have rewritten the mind, and modern differences were explained mainly by culture, markets, and institutions.

Evidence for the assumption remains real. Human beings are genetically very similar, many core emotions and social instincts are plainly species-wide, and the rise of states, literacy, and commerce can explain a great deal of behavioral change without invoking new mental adaptations. Steven Pinker and others, for example, emphasized the civilizing effects of Leviathan, trade, and norms in explaining falling violence, while also noting that claims about evolved group differences carry obvious political dangers and a weak historical record when made carelessly. That caution has kept many scholars attached to the older view, or at least skeptical that recent selection has done much to cognition or temperament.

But a substantial body of experts now argues that the old timetable was too neat. Work in population genetics, including studies of recent adaptive evolution, genome-wide signals of selection, and ancient DNA from West Eurasia, has found abundant evidence that humans kept evolving through the Holocene, sometimes rapidly, under pressures created by farming, cities, diet, disease, and social hierarchy. Lactase persistence is the standard exhibit, because it is undeniable and recent; newer papers go further, reporting enrichment of recent-selection markers in educational and cognitive traits, though those claims are disputed and hard to interpret. Gregory Clark, Nicholas Wade, and others pushed the broader argument that civilization itself became a selection pressure. The current debate is not over whether recent human evolution happened, that point is widely accepted, but over how much of the modern human mind it changed, and how confidently anyone can map genes to behavior.

People Involved
  • Steven Pinker, the Harvard psychologist and author of several influential books on human nature, spent years documenting the long decline in violence across human history. He pointed to twin studies showing substantial heritability of aggressive traits and even noted that certain breeds of animals could be selected for docility in just a few generations. Yet when it came to the possibility that natural selection had continued to shape human populations in the last 10,000 years, Pinker drew back, citing the political inconvenience of such conclusions. His hesitation carried weight. Many readers who followed his work on violence absorbed the message that biology had largely frozen at the end of the Pleistocene. [1]
  • Gregory Clark, the University of California economic historian, examined centuries of English probate records and parish registers. He concluded that between 1200 and 1800 the descendants of the most successful tradesmen and farmers had gradually replaced the violent and impulsive among the English population. The data showed steady selection for traits that favored literacy, numeracy, and self-control. Clark presented his case in plain economic terms, yet his findings sat uneasily beside the prevailing view that nothing biological had changed since the Ice Age. [1]
  • Nicholas Wade, longtime science journalist at The New York Times, published A Troublesome Inheritance in 2014. He argued that denying recent human evolution left scholars unable to make sense of persistent differences in social institutions and economic performance across continents. Wade’s book was widely attacked. Reviewers accused him of reviving discredited racial science, even though his central claim was simply that the same evolutionary processes visible in other species had not exempted humans in the Holocene. [1]
  • David Reich, the Harvard geneticist known for sequencing ancient DNA, stated in 2018 that the denial of biological differences among human populations had become indefensible. In 2024 his team released a massive study of West Eurasian genomes that detected directional selection on variants linked to cognitive performance. Reich’s public warnings and empirical work placed him in the uncomfortable role of challenging the academic consensus he had once helped shape. [3]
  • John Hawks, anthropologist at the University of Wisconsin, led the 2007 analysis that first demonstrated a hundredfold acceleration in genetic evolution over the past 40,000 years. He later criticized newer studies for methodological choices that masked ongoing selection. Hawks’ early paper received respectful citations but little follow-up until larger datasets became available. [6]
  • Nathan Cofnas, an American researcher, published a 2019 paper in Philosophical Psychology arguing that the assumption of equal genetic potential across human groups lacked empirical support. Student protests and faculty complaints followed. Cambridge University nevertheless appointed him as an early-career fellow in philosophy in 2024, a decision that reignited public debate over the boundaries of acceptable inquiry. [7]

“Pinker agrees with Elias that the principal drivers of the civilizing process were the increasing monopoly of force by the state, which reduced the need for interpersonal violence, and the greater levels of interaction with others that were brought about by urbanization and commerce.”— A Troublesome Inheritance
““It could have the incendiary implication that aboriginal and immigrant populations are less biologically adapted to the demands of modern life than populations that have lived in literate state societies for millennia.””— A Troublesome Inheritance

“David Reich is the Harvard geneticist who caused a stir in 2018 when he wrote a piece for the New York Times arguing that “well-meaning people who deny the possibility of substantial biological differences among human populations are digging themselves into an indefensible position, one that will not survive the onslaught of science”.

Resulting Policies

PhD admissions committees at English-speaking universities during the 2010s routinely turned away applicants whose proposals involved evolved group differences in psychology. The stated concern was that such research would face grant difficulties and public backlash. The pattern created a de facto filter on what questions could be asked by the next generation of scholars. [2]

Cambridge University’s Faculty of Philosophy reviewed Nathan Cofnas’s 2019 paper challenging the assumption of equal group potential. Despite protests from students and some faculty labeling the work questionable, the department appointed him to a three-year early-career fellowship in 2024. The decision signaled that certain institutional barriers were not absolute. [7]

Undergraduate psychology curricula presented The Bell Curve as a text containing elementary errors and logical embarrassments, citing Stephen Jay Gould’s review as authoritative. The portrayal discouraged students from reading the original work and steered research agendas away from questions about genetic contributions to group differences in intelligence. [12]
