Teeth A Very Short Introduction

Teeth are a vital component of vertebrate anatomy and a fundamental part of the fossil record. It was the evolution of teeth, associated with predation, that drove the evolution of the wide array of fish, amphibians, reptiles, and then mammals. Peter S. Ungar looks at how, without teeth, none of these developments could have occurred.

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.

This text is about the central role of evolution in shaping the nature and diversity of the living world. It describes the processes of natural selection, how adaptations arise, and how new species form, as well as summarizing the evidence for evolution

This entertaining Very Short Introduction reflects the enduring popularity of archaeology - a subject which appeals as a pastime, career, and academic discipline, encompasses the whole globe, and surveys 2.5 million years. From deserts to jungles, from deep caves to mountain tops, from pebble tools to satellite photographs, from excavation to abstract theory, archaeology interacts with nearly every other discipline in its attempts to reconstruct the past. In this new edition, Paul Bahn brings the text up to date, including information about new discoveries and interpretations in the field, and highlighting the impact of developments such as the potential use of DNA and stable isotopes in teeth, as well the effect technology and science are having on archaeological exploration.

Relative newcomers within the story of evolution, mammals are hugely successful and have colonized land, water, and air. Tom Kemp discusses the great diversity of mammalian species, and looks at how their very disparate characteristics, physiologies, and behaviours are all largely driven by one uniting factor: endothermy, or warm-bloodedness.

A compact introduction to modernism--why it began, what it is, and how it hasshaped virtually all aspects of 20th and 21st century life

One of the most powerful frameworks for understanding human behaviour is evolutionary psychology. Evolutionary psychology takes the view that the brain, just like any other part of our body such as teeth or hands, has been shaped by the processes of natural and sexual selection. How we think,and the way we use logic or assess problems, has its roots in behaviour which enabled our ancestors to survive and reproduce successfully. Using this perspective, the divide between nature and nurture evaporates, as humans are shown to be the product of their genes and biology, as well as theirenvironment, social groups, and families.In this Very Short Introduction Maryanne Fisher show how examining the historic lives of our ancestors can provide insight into of our modern psychology, especially when we add data from modern-day hunter-gatherer societies, comparative studies on the great apes, and the fossil record. Surprisingly,alongside these traditional data sources, evolutionary psychology can also use surveys from university students, romance novels, and even patterns in online shopping behaviour. Throughout, Maryanne Fisher discusses how drawing together this diverse data allows us to understand the complexity ofhumans in a powerful mannerABOUT THE SERIES:The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area.

Astrophysics is said to have been born when Isaac Newton saw an apple drop in his orchard and had the electrifying insight that the Moon falls just like that apple. James Binney shows how the application of physical laws derived on Earth allows us to understand objects that exist on the far side of the Universe.
