“The scaling up of human social organization into mega-groups comprising millions (even hundreds of millions in modern nation states) would not have been possible without the human facility for culture acquisition and transmission on a massive scale.”

“The evolution of sexually selected traits can create particular kinds of vulnerabilities to mental disorders, which are often skewed in their sex ratios. Examples of mental disorders where sexual selection may play an important role include eating disorders, sexual dysfunction and schizophrenia.”

“The idea of mismatch is based on the fact that adaptations are shaped by selection within a given environment. If the environment changes rapidly and radically, some biological systems run the risk of becoming mismatched to the new environment. This is also referred to as -genome lag-.”

“Parental investment theory predicts that, on average, the sex that invests more in its offspring, including the size of gametes, gestation, lactation and child rearing, will be more selective when choosing a mate, and the less-investing sex will engage in more intra-sexual competition for access to mates.”

“This is not to say that I have outgrown those elemental desires that drew me to transhumanism—just that they express themselves in more conventional ways. Over the intervening years, I have given up alcohol, drugs, sugar, and bread. On any given week, my Google search history is a compendium of cleanse recipes, high-intensity workouts, and the glycemic index of various exotic fruits. I spend my evenings in the concrete and cavernous halls of a university athletic center, rowing across virtual rivers and cycling up virtual hills, guided by the voice of my virtual trainer, Jessica, who came with an app that I bought. It’s easy enough to justify these rituals of health optimization as more than mere vanity, especially when we’re so frequently told that physical health determines our mental and emotional well-being. But if I’m honest with myself, these pursuits have less to do with achieving a static state of well-being than with the thrill of possibility that lies at the root of all self-improvement: the delusion that you are climbing an endless ladder of upgrades and solutions. The fact that I am aware of this delusion has not weakened its power over me. Even as I understand the futility of the pursuit, I persist in an almost mystical belief that I can, through concerted effort, feel better each year than the last, as though the trajectory of my life led toward not the abyss but some pinnacle of total achievement and solution, at which point I will dissolve into pure energy. Still, maintaining this delusion requires a kind of willful vigilance that can be exhausting.”

“When an organism can react in a protective way for little cost but potentially huge benefit (e.g. avoiding death), the optimal system expresses many false alarms. Vomiting may only cost only a few hundred calories and a few minutes, whereas not vomiting risks death from poisoning.”

“The growth in hominin socialisation can be linked with the development of greater abilities of mentalising - the recursive understanding of another's intent.”

“The great questioner. the social animal, in a limitless world of mystery, intrigue and dangers. Why did the sun rise and fall and influence the growth of plants and food? What were the stars that moved silently through the sky and the planets that wandered between them? What had happened to our relatives who had died, or what would happen to our children in the future? What excitement and wonder when they met an outside group, tried to communicate and exchanged and bartered goods, hearing tales of other lands and frightening beasts.”

“We are sole hominin survivors, but not the inevitable masters. Luck, as much as biology, might have been key to sapiens’ place in the world. Our existence as a species is due to a series of devastating, largely random catastrophes, each of which overhauled the planet and its ecosystems, providing new opportunities: from the meteorite impact that killed the dinosaurs but unleashed mammals through to climate change in Africa some 2 million years ago and the emergence of the great savannahs.”
“For most of human evolutionary history our species lived as hunter-gatherers; hence, much of our cognition and behavior is adapted to this way of life. Given the magnitude of the sociocultural, economic and lifestyle changes experienced by Homo Sapiens over the last 10,000 years, in particular the last several hundred years, aspects of human psychology may be maladapted to modern ways of life.”
