Like gene sequences, transcription profiles are heritable, thus providing a substrate for evolution. Evidence for local adaptation in the water flea has been already provided, at different levels: resistance to parasites, predation, and species composition. Exploiting the potential of biological archives, we will hatch past populations of Daphnia from the resting egg bank and compare them to recent populations in a large scale ...
