Much recent research in evolutionary developmental biology has
focused on the origin of new body plans. However, most evolutionary
change at the population and species level consists of tinkering:
small-scale alterations in developmental pathways within a single
body plan. Such microevolutionary events have been well studied on
a population genetic level and from the perspective of adaptive
phenotypic evolution, but their developmental mechanisms remain
poorly studied.
This book explores both theoretical and practical issues of
tinkering. It features a wide range of perspectives to address
several fundamental questions. How does tinkering occur
developmentally, and how is it manifested phenotypically? Are the
developmental mechanisms by which tinkering occur different from
those that underlie larger evolutionary changes? What are the
developmental constraints on tinkering? And how do we test
hypotheses about microevolutionary shifts in development from the
fossil record?
With contributions from experts in a range of fields, this
fascinating book makes exciting reading for anyone studying
evolution, developmental biology or genetics.
