In this landmark book of popular science, Daniel E. Lieberman—chair of the department of human evolutionary biology at
Harvard University and a leader in the field—gives us a lucid and engaging account of how the human body evolved over
millions of years, even as it shows how the increasing disparity between the jumble of adaptations in our Stone Age
bodies and advancements in the modern world is occasioning this paradox: greater longevity but increased chronic
The Story of the Human Body brilliantly illuminates as never before the major transformations that contributed key
adaptations to the body: the rise of bipedalism; the shift to a non-fruit-based diet; the advent of hunting and
gathering, leading to our superlative endurance athleticism; the development of a very large brain; and the incipience
of cultural proficiencies. Lieberman also elucidates how cultural evolution differs from biological evolution, and how
our bodies were further transformed during the Agricultural and Industrial Revolutions.
While these ongoing changes have brought about many benefits, they have also created conditions to which our bodies are
not entirely adapted, Lieberman argues, resulting in the growing incidence of obesity and new but avoidable diseases,
such as type 2 diabetes. Lieberman proposes that many of these chronic illnesses persist and in some cases are
intensifying because of “dysevolution,” a pernicious dynamic whereby only the symptoms rather than the causes of these
maladies are treated. And finally—provocatively—he advocates the use of evolutionary information to help nudge, push,
and sometimes even compel us to create a more salubrious environment.
