WHAT IT’S REALLY ABOUT
Evolutionary anthropologist reveals crucial, misunderstood role of modern fathers
- Dr. Anna Machin argues that dominant cultural narratives about fathers are fictional, unscientific, and damaging to men, children, and families. Drawing on evolutionary anthropology and contemporary research, she explains that human males are biologically primed to parent and that male parental investment was pivotal to our species’ survival. Fathers and mothers are equal in importance but distinct in function: mothers specialize in core nurturing while fathers uniquely scaffold children’s social skills, resilience, and entry into the wider world. She calls for cultural, medical, and policy changes—especially better paternity leave and father-focused support—to recognize fathers as true co-parents rather than optional extras.
IDEAS WORTH REMEMBERING
5 ideasMen are biologically primed to parent, not secondary or non‑instinctive carers.
Contrary to the myth that only mothers are ‘natural’ parents, scans show men’s brains and hormones reshape for caregiving, with increases in empathy, risk detection, and executive function comparable to mothers—just triggered differently and often later.
Human fathers evolved because they were essential to our survival.
As big-brained, bipedal babies were born increasingly helpless, maternal and female-kin care became insufficient; male parental investment emerged to keep infants alive, making humans a rare mammal—and the only ape—where fathers routinely invest in offspring.
Fathers and mothers have distinct, complementary developmental roles.
While both parents nurture and attach, mothers’ peak brain activation is in ancient limbic regions linked to core caregiving, whereas fathers’ peaks in neocortical social cognition support ‘scaffolding’ children into the wider world—social skills, networks, risk-taking, and resilience.
Father–child play, especially rough-and-tumble, is a developmental engine.
Physical, high-energy play rapidly releases bonding hormones and teaches reciprocity, empathy, risk assessment, and persistence; it’s a time-efficient way for often time-poor fathers to build strong bonds and foster resilience from infancy through adolescence.
Fathers profoundly influence adolescent mental health and self‑esteem.
Research shows the quality of the father–child relationship predicts teens’ resilience, depression and anxiety risk, and ability to handle daily stress—often with particularly strong protective effects for girls in patriarchal cultures.

If a woman has a problem we ask, ‘What can we do to fix society?’ If a man has a problem, we ask, ‘What can men do to fix themselves?’
