SummaryDarwins theory on the origin of species by means of natural selection rests on the assumption that in every generation the progeny are not exactly alike, but vary slightly. Those that fit best to the conditions survive and propagate their kind. In order to identify genes that when mutated cause the variation of animal morphology in evolution, it is necessary to understand growth and development of shape and form. In the department of genetics muscle stem cells, as well as the development of integumentary structures and the pigment pattern of the zebrafish are investigated.
