In the Developmental Cell magazine appeared an article of scientists from the University Pablo de Olavide in Seville, Spain, under the leadership of Jose Gomez-Skarmeta, that the appearance of an additional copy of the gene in the genome Hoxd13 of zebra fish Danio rerio causes that the fins of the fish turn into foot-like feet of land animals (see the photo above). As reported, Hoxd13 gene is a large gene of family 5hox, which regulate the growth of limbs during embryonic development, it is the activity of these genes determine the form and limb size of fish, so the artificial increase in the activity of the gene Hoxd13 caused an unusual effect of fish embryos- with a double dose of the gene Hoxd13 fish had fins, which lost its characteristic fan-shaped form and became rounder like paws with signs of this cartilage and bone, which is not typical for the normal fish zebra Danio rerio.
