The subject of evolution occupies a special, and paradoxical,
place within biology as a whole. While the great majority
biologists would probably agree with Theodosius Dobzhansky's
dictum that ``nothing in biology makes sense except in the
light of evolution'', most can conduct their work quite happily
without particular reference to evolutionary ideas. ``Evolution''
would appear to be the indispensible unifying idea and, at the
same time, a highly superfluous one.
Yet, the marginality of evolutionary biology may be
changing. More and more issues in biology, from diverse
questions about human nature to the vulnerability of ecosystems,
are increasingly seen as reflecting evolutionary events.
A spate of popular books on evolution testifies to this
development. If we are to fully understand these matters,
however, we need to understand the processes of evolution
that, ultimately, underlie them. This thematic issue of
BioEssays is a survey of these processesÐand the ways
they shape the properties of living things, from bacteria to
humans.
The rest of the essay is a brief description of the articles in a special issue of BioEssays on evolutionary processes.
