A raunchy new 'Big History' tells the story of sex, but raises some unanswered questions
The book is one of the latest additions to the popular “Big History” genre.

- Baker is a science writer with a PhD in Big History and one of the writers behind the Big History Crash Course on YouTube.
- Sex: Two Billion Years of Procreation and Recreation – David Christian (Black Inc.) The book is divided into three sections.
- This development was followed by the rapid appearance of diverse animal species, from fish and amphibians to reptiles, insects, dinosaurs, birds and mammals.
- The final section, Cultural Afterglow, which extends from 315,000 years ago to the present, traces the history of Homo sapiens from hunter-gatherers, to the first agrarian societies, and on to the present day.

Evolution
- But to weave his “grand narrative of sex” he also anthropomorphises reproduction of even the earliest living organisms.
- His argument is that asexual reproduction at this time of catastrophic climatic conditions was causing overpopulation and that sexual reproduction would slow population growth.
- A few pages later, he writes “furthermore, sex bequeathed upon those hardy, horny eukaryotes the potential for rapid evolution into increasingly complex species”.
- The long bow being drawn between “sexual” behaviour involving the first exchange of DNA by single-celled organisms and the first modern humans is long indeed.
- He notes differences in anatomy and genital size, and considers variations in practices such as masturbation and sexual partnering, including polygamy, monogamy, promiscuity, homosexual and bisexual behaviour.
- He delves into the issues of pleasure, romantic love and parenting, and related forms of social organisation, such as patriarchy and matriarchy.
- It is, however, the evolution of human culture that radically changes everything.
The future of sex
- Informing some of Baker’s thinking are statistics about the number of Millennials “projected to never get married in their lifetimes” and the decline in rates of casual sex.
- It would involve more hook-ups and the growing replacement of human-to-human sex with sex dolls and bots.
- In a “possible future”, he considers how internet technology might lead to virtual, AI-driven partnered sex.
- Finally, in a “preposterous future”, he suggests that sex could cease to be important to living organisms at all.
- While Baker’s deliberations are interesting and worth pondering, it is difficult to accept his claim that “the liberalisation of attitudes towards sex has released human sexuality from the grip of culture”.
- The “grip of culture” is still ever-present in the policing of female sexual behaviour, which continues to the present day the world over.
- While there is an impressive list of references at the end of the book, Baker admits that many of the beliefs he shares about the evolution of sex are not certain.
- If Baker’s book helps this endeavour by getting us to think about human sexuality more deeply, then it will prove worthwhile.
