IRCM researchers explain how evolution has equipped our hands with 5 fingers

(University of Montreal) The research team of Professor Marie Kmita just responded in part to the question: why do we have five fingers in each hand, knowing that human hand comes from the fish fin rays, which have more than five? The results of the study published in Nature suggests that this major morphological change did not occur through the acquisition of new genes but by simply modifying their activities.
