Diet is key to understanding the past, present, and future of our species. Much of human evolutionary success can be attributed to our ability to consume a wide range of foods. On the other hand, recent changes in the types of foods we eat may lie at the root of many of the health problems we face today. To deal with these problems, we must understand the evolution of the human diet. Studies of traditional peoples, non-human primates, human fossil and archaeological remains, nutritional chemistry, and evolutionary medicine, to name just a few, all contribute to our understanding of the evolution of the human diet. Still, as analyses become more specialized, researchers become more narrowly focused and isolated. This volume attempts to bring together authors schooled in a variety of academic disciplines so that we might begin to build a more cohesive view of the evolution of the human diet. The book demonstrates how past diets are reconstructed using both direct analogies with living traditional peoples and non-human primates, and studies of the bones and teeth of fossils. An understanding of our ancestral diets reveals how health relates to nutrition, and conclusions can be drawn as to how we may alter our current diets to further our health.
We are interested in the evolution of hominin diets for several
reasons. One is the fundamental concern over our present-day eating
habits and the consequences of our societal choices, such as
obesity prevalent in some cultures and starvation in others.
Another is that humans have learned to feed themselves in extremely
varied environments, and these adaptations, which are fundamentally
different from those of our closest biological relatives, have to
have had historical roots of varying depth. The third, and the
reason why most paleoanthropologists are interested in this
question, is that a species' trophic level and feeding adaptations
can have a strong effect on body size, locomotion, "life history
strategies," geographic range, habitat choice, and social
behavior.
Teeth are amazing - the product of half a billion years of evolution. They provide fuel for the body by breaking apart other living things; and they must do it again and again over a lifetime without themselves being broken in the process. This means that plants and animals have developed tough or hard tissues for protection, and teeth have evolved ways to sharpen or strengthen themselves to overcome those defences. And just as different jobs require different tools, animals with different diets have different shaped teeth to deal with the variety of foods that they eat. In this Very Short Introduction, Peter S. Ungar, an award-winning author and leading scientist, presents the story of teeth. Ungar outlines the key concepts, including insights into the origin of teeth and their evolution. Considering why teeth are important, he describes how they are made, and how they work, including their fundamental importance in the fossil record. Ungar finishes with a review of mammal teeth, looking at how they evolved and how recent changes to our diet are now affecting dental health.
