Tomislav Domazet-Loso and Diethard Tautz from the Max Planck Institute for Evolutionary Biology in Plon, Germany, have systematically analyzed the time of emergence for a large number of genes - genes which can also initiate diseases. Their studies show for the first time that the majority of these genes were already in existence at the origin of the first cells. The search for further genes, particularly those which are involved in diseases caused by several genetic causes, is thus facilitated. (source: mpg.de)
