Synopsis

We are the product of our evolutionary history and this history colours our everyday lives - from why we kiss to how religious we are. In How Many Friends Does One Person Need? Robin Dunbar explains how the distant past underpins our current behaviour, through the groundbreaking experiments that have changed the thinking of evolutionary biologists forever.

He explains phenomena such as why 'Dunbar's Number' (150) is the maximum number of acquaintances you can have, why all babies are born premature and the science behind lonely hearts columns. Stimulating, provocative and highly enjoyable, this fascinating book is essential for understanding why humans behave as they do - what it is to be human.

About this title

Review

Lucid and provocative.--Bryce Christensen"Booklist" (11/01/2010)

[A] fascinating volume that ranges widely across time, space and human practices...Tossing off light-hearted examinations of such fairly innocent topics as why we kiss and why all babies look very much alike, Dunbar is unafraid to tackle sensitive and controversial issues as well. These essays deal with race, gender, intelligence, class, and nationality in dispassionate and unflinching ways that do not seek to cushion hard facts with mealy-mouthed sanctimony...Far from being a catalogue of gloom and doom, this book leaves the reader marvelling at how far homo sapiens has come, and how far we might yet ascend.--Paul Di Filippo"Barnes & Noble Review" (03/03/2011)

It is an entertaining as well as informative read.--Rosalie West"Portland Book Review" (06/01/2011)

For the past thirty years [Dunbar] has conducted research designed to uncover the workings of our ancestral hardware: to decode the scripts that drive much of our behavior and make us what we are as a species. Although Dunbar emphasizes the value of kin, he is anything but a sentimentalist. In this book, he chases after averages and patterns, after predictive links between current behavioral and physical traits and what, in the Pleistocene or Neolithic past, would most likely have been mating or survival advantages...In general, understanding the Darwinian back-story of our species is arguably a way to short-circuit the infelicities of our gut responses: a way to combat gut-level racism, sexism, beauty/symmetry biases, height biases, ageism, and the many variants of tribalism and jingoism...Dunbar shows that, if we go far enough back in our family trees, we are all the product of a tangled skein of heroes and villains, of conquering populations and conquered ones, of dominant and minority races, of in-groups and out-groups. Whether we as individuals call ourselves one or the other is often just a matter of how far back in time we set our stakes combined with the limits of our instruments for probing ourselves. Knowledge such as this may well be the only way out of the ancestral cave.--Michele Pridmore-Brown"Los Angeles Review of Books" (05/24/2011)

An eclectic collection of essays on humanity and evolution with something for everyone. Dunbar explains, among other things, why monogamists need big brains, why it is worth buying a new suit for an interview, how to interpret an advert in a lonely hearts column, the perils of messing with evolution and, of course, how many friends one person needs (150 as it happens, aka "Dunbar's number"). He speaks with authority and seduces us as only a master storyteller can.--Kate Douglas, New Scientist
