The contributions to this book aim at understanding, from a evolutionary perspective, the impact of stress on biological systems.

The fact that different genotypes may respond differently to environmental stress may be of key importance to the maintenance of genetic variation in metabolic traits.

Studies of the stress or heat shock response in . illustrate this point. At the cellular level, heat shock proteins (Hsps) function as molecular chaperones, mini
