Biology Is Right-Wing? This Leftist Scientist Begs to Differ - Gary Clark (#23)
Dr Gary Clark is an evolutionary biologist and paleoanthropologist whose career spans fossil anatomy, sexual dimorphism and fieldwork with Aboriginal communities in Australia. His conversation with the Beyond Gender hosts lands at a pivotal moment for Britain: the Cass Review concluded that NHS gender medicine had abandoned its evidentiary foundations, and Clark's argument — that denying biological sex is not progressive but anti-scientific — speaks directly to the institutional failures that made that possible.
Dr Gary Clark is not the kind of scientist gender-ideology critics are typically accused of citing. An evolutionary biologist and paleoanthropologist, he spent formative years living and working with Aboriginal communities in Australia's Western Desert, studying human behaviour across cultures and deep time. His research focuses on sexual dimorphism in the fossil record — the measurable, skeletal differences between male and female bodies that stretch back millions of years. He has also written on Carl Jung and the evolutionary sciences, arguing that even depth psychology must be grounded in biological reality. In conversation with Stella O'Malley, Mia Hughes and Dr Bret Alderman, Clark explains how gender ideology spread through Australian universities and why its trajectory mirrors what happened inside British institutions. His central argument is striking in its simplicity: the observable differences between male and female — recorded in every known human society and legible in the bones of our prehistoric ancestors — are not political constructs. They are biological facts four million years of evolution have produced. To claim otherwise, he argues, is not a progressive intellectual position but a rejection of the scientific method itself. This matters acutely in Britain. The Cass Review, published in April 2024 after four years of inquiry, found that the NHS gender service for children had been operating without an adequate evidence base. The clinical pathway from social transition to puberty blockers to cross-sex hormones had been normalised inside a system that had stopped asking hard biological and psychological questions. Clark's account of how academia suppresses those same questions in Australia offers a recognisable picture: institutions that elevated ideological consensus above scientific rigour, and professionals who paid a professional price for dissenting. British academics and clinicians have described similar pressures for years. Researchers studying sex-based differences in medicine, psychiatry and developmental psychology have reported being labelled politically motivated simply for following their data. Clark's experience — watching evolutionary biology branded as inherently right-wing — will resonate with UK scientists who have found that what their findings say matters far less than how those findings are perceived to align with prevailing orthodoxy. The episode poses a pointed question: if the evidence for biological sex differences is overwhelming across the fossil record and every studied human culture, why do major universities treat it as a fringe position? Clark also addresses the postmodern distortion of Jungian psychology — a thread with particular resonance in Britain, where Jungian-influenced psychotherapy has a substantial institutional presence. He argues that Jung's insights into masculine and feminine patterns were grounded in evolutionary observation, not in the gender essentialism critics now project onto them. Stripping that biological grounding away, Clark suggests, produces a psychology of meaning without roots, which may help explain why the psychotherapeutic mainstream has found it so difficult to mount coherent resistance to gender ideology. For British listeners living through the aftermath of Tavistock's closure and the careful reconstruction of NHS gender services, Clark offers a form of scientific ballast. The claim that biology is inherently right-wing was never empirically defensible; it was politically convenient. As England attempts to rebuild its approach to gender medicine on firmer evidentiary foundations, scientists willing to defend the factual basis of biological sex — at personal and professional cost — become correspondingly harder to dismiss.
