Diskontinuierlich aktive Gene und Evolution Eine Diskussion am Beispiel der Archaeognatha (Insecta)

Discontinuous activity of genes and evolution - a discussion based on examples of the Archaeognatha (Insecta) On the basis of examples, mainly from the group of Archaeognatha (Insecta) it seems probable that, in multicellular organisms, there is not only a discontinuous activity of genes and groups of genes during the individual development, but also during the phylogenesis. The possibility that silent genes can be reactivated is probably an essential reason for the existence of parallelisms and homologous tendencies. Both conceptions have a complementary importance for an establishment of taxa ana the reconstruction of phylogenesis and are defined according to evolutionary genetics. The examples are discussed and the necessity of similar comparative studies in other supraspecific taxa is emphasized.
