"New research will increasingly be driven by ... evolutionary theory," says Melvin Konner. Ann Cale Kruger
The anthropologist and physician Melvin Konner began his career in the late 1960s studying how hunter-gatherer people in southern Africa’s Kalahari Desert raised their children. His new book, The Evolution of Childhood, is an effort (960 pages, decades in the works) to explain why children everywhere develop, behave, mature and think as they do. Konner, a professor at Emory University, responded by e-mail to executive editor Terence Monmaney’s questions.
How will our understanding of childhood change in the coming decades?
The most impressive findings will come from genetics and brain imaging. Most traits we care about will be influenced by not one or a few but hundreds of genes. Faster and cheaper methods of measurement and analysis will reveal remarkable patterns. Brain imaging has been difficult in infants and children because they don’t stay still, but new methods are beginning to compensate for that, and we will know much more about brain function in developing children in real time. This will enable us to separate the aspects of brain function that are maturational and less influenced by the environment from those that respond most readily to nurture and learning. Periods when children may be sensitive to intervention, to the extent that they are important, will be better defined. At the same time, new research will increasingly be driven by hypotheses from evolutionary theory, even more so as Americans’ ignorance about evolution is overcome.
How might scientific insights affect our perception of childhood?
When I think about how our basic views have changed in my lifetime, I think: genes being more influential, infants being more competent, teenage brain growth being more dramatic, and powerful environmental interventions being more specific than we thought. Biology will continue to guide intervention, just as figuring out how the metabolic disorder PKU worked on a chemical level enabled us to test all newborns for it and design a diet for affected babies to prevent mental retardation. Sophisticated developmental analysis of conduct disorder has led to school-based psychological interventions that make a huge difference. Understanding teen brain immaturity against the background of rising hormones is changing education and legal practice. Medications like stimulants for attention deficit and hyperactivity are both over-prescribed and under-prescribed because we’re not good at finding out which child needs them. There will be hundreds more such insights as the complex interplay of biological, psychological and cultural factors is better understood. Some innovative interventions will be in parenting, some in education, some in medicine, some even in play. New discoveries will trounce old ideologies and open all our minds about what to do for children and how to do it.
Is the experience of childhood itself likely to change?
It depends. Sure, it will be great to know more about how to help those children who are already highly privileged to become even better nurtured and educated and turn into ever more effective and happy adults. But scientific advances will matter little without very big policy changes. We already know that it is bad for children to be abused, neglected, ill without treatment, ineptly educated, sexually exploited and enslaved, yet we do so little to combat these scourges—and I am talking, by the way, about problems inside the U.S., not just on the other side of the planet. We need knowledge but we also need will, and we need a moral compass that will lead us to a better environment for all children everywhere.

I find this fascinating, I am a parent of two young girls and I am always on the look out for this sort of information. I'm headed to amazon next :) I wonder what mr konner thinks about the long term effects of newer technology on children and the way they develop. There are all kinds of gizmos and gadgets geared toward very young children, yet a pile of rags and an empty box hold a 10 month olds interest far longer. Many of these gizmos seem to be trying to appeal to parents with the notion that it will teach their child for them, ( and do a better job) thus giving the parent guilt free, free time. I just don't believe that a book that will record my voice reading it out loud is going to do the same job as me holding my girls and reading it in person to them. Its such a sad and depressing thought that because mommy and daddy are at work all day (don't get me started on the economy and the politics involved there!) that the closest a child can get to quality time is listening to mommy on a recording.
Teachers, scholars, anthropologists, scientist, doctors and so on are my celebrities, I loved going to class and listening to the proffesors lecture. Someday I will find a way to go back, but until then, it's books and articles like this that hold me over.
Enough of my rambling. :)

I hope somewhere within 960 pages there is at least a mention of children being destroyed my law and money.
