The Hunter-Gatherer Principle

In his unique science book, The Hunter-Gatherer Principle: Evolutionary Biology and the Case for Sex-Based Female Sports, bestselling author, award-winning historian, and women's sports advocate Lochlainn Seabrook, zeroes in on a seldom discussed topic: the enormous physical differences between human males and human females, an ancient inheritance from our prehistoric hunting and gathering ancestors. Genetically established in the Homo line at least as far back as the Pliocene Era, these dissimilarities, known collectively as sexual dimorphism, provide irrefutable proof that biological men competing with or against biological women is unfair, unethical, unsafe, and possibly deadly, and as such should also be unlawful.

Along with evolutionary biology the author relies on various other disciplines, including anthropology, sociobiology, neurobiology, sports science, and statistical science, as well as a number of real world examples, to demonstrate both the physical superiority and the resulting advantages the average biological man has over the average biological woman. His system of evidence, which he calls "The Hunter-Gatherer Principle," includes an absorbing look at the sexual dimorphism of our Stone Age ancestors and relatives, such as Homo erectus and Homo heidelbergensis, covering the innate physical and psychological traits and disparities between human males and females dating to nearly 4 million years ago. Further substantiating his views he takes a close look at the differences between men's and women's skulls and pelvises, more evidence showcasing the massive dissimilarities between natal males and natal females. Seabrook's generously illustrated book ends with an exploration of rational solutions to the many controversial unscientific and anti-scientific issues raised by transgender policies, ideologies, politics, and opinions.

The only work of its kind, the book contains an introduction, endnotes, bibliography, detailed index, and an appendices section that incorporates pertinent reading material, such as women's sports related laws, President Trump's 2025 executive order banning biological men from biological women's sports, and the complete text of the United Kingdom's Supreme Court ruling on the legal definition of a woman. The author is not anti-transgender. He is a pro-science, pro-Constitution exponent who believes in defending and securing the individual civil rights, freedoms, and protections of all Americans. The Hunter-Gather Principle is available in paperback and hardcover. (All text copyright © Sea Raven Press.)
