A biologist by training, Raihani looks at where and how collaborative behavior emerges throughout the animal kingdom, and what problems it solves. She reveals that the species that exhibit cooperative behavior-teaching, helping, grooming, and self-sacrifice-most similar to our own tend not to be other apes; they are birds, insects, and fish, occupying far more distant branches of the evolutionary tree. By understanding the problems they face, and how they cooperate to solve them, we can glimpse how human cooperation first evolved. And we can also understand what it is about the way we cooperate that has made humans so distinctive-and so successful.
What The Reviewers Say
Andrew Robinson,
Nature
[Raihani's] rewarding analysis ranges from genetics to politics, and from the individual to the international, including the COVID-19 pandemic..
Jon Turney,
The Arts Desk
[Raihani] starts at the simplest level. Humans do not take centre stage until halfway through, after a long look at the roots of co-operation between 'selfish' genes, in cells, then multicellular organisms, and groups of organisms.
Dan Hitchens,
The Times (UK)
The book starts promisingly enough, with Raihani gathering weird and wonderful examples of the “social instinct” among humans and our fellow creatures.
Publishers Weekly
