Jumping Genes and Cichlids' Egg-Spots: How Evolution Creates new Characteristics

Posted by External 11 days ago General — The evolution of new traits with novel functions has always posed a challenge to evolutionary biology. Studying the color markings of cichlid fish, scientists were now able to show what triggered these evolutionary innovations, namely: a mobile genetic element in the regulatory region of a color gene.
