Explores how our evolutionary history has shaped a phenomenon every reader will have experienced – childhood. Tracking deep into our evolutionary history, anthropological science has begun to unravel one particular feature that sets us apart from the many, many animals that came before us – our uniquely long childhoods. Growing Up Human looks at how we have diverged from our ancestral roots to stay ‘forever young’ – or at least what seems like forever – and how the evolution of childhood is a critical part of the human story. Beginning with a look at the ways animals invest in their offspring, the book moves through the many steps of making a baby, from pair-bonding to hidden ovulation, points where our species has repeatedly stepped off the standard primate path. From the mystery of monogamy to the minefield of modern parenting advice, biological anthropologist Brenna Hassett reveals how differences between humans and our closest cousins lead to our messy mating systems, dangerous pregnancies, and difficult births, and what these tell us about the kind of babies we are trying to build. Using observations of our closest primate relatives, the tiny relics of childhood that come to us from the archaeological record, and the bones and teeth of our ancestors, science has started to unravel the evolution of our childhood right down the fossil record. In our species investment doesn’t stop at birth, and as Growing Up Human reveals, we can compare every aspect of our care and feeding, from the chemical composition of our milk to our fondness for formal education from ancient times onwards, in order to understand just what we evolved our weird and wonderful childhoods for.

Imagine you are a hunter-gatherer some 15,000 years ago. You've got a choice - carry on foraging, or plant a few seeds and move to one of those new-fangled settlements down the valley. What you won't know is that urban life is short and riddled with dozens of new diseases; your children will be shorter and sicklier than you are, they'll be plagued with gum disease, and stand a decent chance of a violent death at the point of a spear.

Why would anyone choose this? This is one of the many intriguing questions tackled by Brenna Hassett in Built on Bones. Using research on skeletal remains from around the world, this book explores the history of humanity's experiment with the metropolis, and looks at why our ancestors chose city life, and why they have largely stuck to it. It explains the diseases, the deaths and the many other misadventures that we have unwittingly unleashed upon ourselves throughout the metropolitan past, and as the world becomes increasingly urbanised, what we can look forward to in the future.

Telling the tale of shifts in human growth and health that have occurred as we transitioned from a mobile to a largely settled species. Built on Bones offers an accessible insight into a critical but relatively unheralded aspect of the human story: our recent evolution.
