This book adopts an experimental approach to understanding the
mechanisms of evolution and the nature of evolutionary processes,
with examples drawn from microbial, plant and animal systems. It
incorporates insights from remarkable recent advances in
theoretical modelling, and the fields of molecular genetics and
environmental genomics. Adaptation is caused by selection
continually winnowing the genetic variation created by mutation. In
the last decade, our knowledge of how selection operates on
populations in the field and in the laboratory has increased
enormously, and the principal aim of this book is to provide an
up-to-date account of selection as the principal agent of
evolution. In the classical Fisherian model, weak selection acting
on many genes of small effect over long periods of time is
responsible for driving slow and gradual change. However, it is now
clear that adaptation in laboratory populations often involves
strong selection acting on a few genes of large effect, while in
the wild selection is often strong and highly variable in space and
time. Indeed these results are changing our perception of how
evolutionary change takes place. This book summarizes our current
understanding of the causes and consequences of selection, with an
emphasis on quantitative and experimental studies. It includes the
latest research into experimental evolution, natural selection in
the wild, artificial selection, selfish genetic elements, selection
in social contexts, sexual selection, and speciation.
