Speciation is characterised by its proper time dynamics with phases of accelerated and retarded evolution. Typically phenotypic differentiation between populations is larger than genotypic differentiation. Traits of stickleback evolve quickly to extremes and hence have led to the development of phenotypi- cally distinct ecological forms. We study (1) metapopulation structure of threespine stickleback in Flanders in order to detect evolutionary parallellism. (2) We also find out to what degree does phenotypic differentiation reflect its evolution.
