Define 'female' and 'male' across policy and law using a cross‑species, reproductive criterion (egg‑producer vs sperm‑producer during reproductive phase). This definition is proposed as a stable anchor that acknowledges biological exceptions (intersex, hermaphroditism, within‑sex variation) without dissolving categorical sex for medical, legal, and institutional purposes.
— If adopted as an organizing definitional principle, it would simplify and harden the basis for statutes, medical protocols, sports eligibility rules, and data collection while forcing clearer treatment of edge cases in policy and litigation.

Stewart‑Williams’ argument that humans are best understood as a mutual‑mate‑choice species weakens simplistic appeals to a rigid sex binary as a policy or cultural anchor; the article supplies an evolutionary, evidence‑based challenge to the claim that one sex should dominate mating or parental roles, directly relating to debates captured by the existing idea about biology being used as a fixed social anchor.

The article provides cross‑species evidence and mechanisms (fecundity selection for larger females; intrasexual competition for larger males) that reinforce biological accounts of sex differences; those accounts are precisely what the 'Sex Binary as Biological Anchor' idea describes being used as a foundation in public discourse about gender and policy.

By emphasizing early‑life appearance of sex differences and arguing for nontrivial innate contributions, the excerpt reinforces narratives that treat biological sex as a foundational axis for policy and social classification.

Steve Stewart‑Williams’ excerpt explicitly proposes and defends a cross‑species egg/sperm‑based definition of female and male and uses that to rebut reformist and abolitionist critiques.
