During the last decades a breakthrough in the understanding of the mechanisms controlling development has been achieved. This has been possible, in great part, by the use of various experimental approaches.
This book focuses on topics concerning some of the processes involved in development, the main emphasis being on the genetic and molecular mechanisms in the evolutionary context. Drosophila is used as an experimental model for the genetic approach to the understanding of behaviour.
