    • Abstract:
      To detect whether these shapes came from an ancestral bat wing or evolved independently, Sears and her colleagues investigated the embryology of different bat species and the genes responsible for the tissue's development. The findings provide important evidence for how skin layers fuse together to form bats' essential flight membrane, says University of Melbourne biologist Charles Feigin, who was not involved in the new study. BATS HAVE DONE something no other mammal ever has: the leathery-winged beasts evolved powered flight thanks to specialized membranes called patagia connecting their limbs and digits to the rest of their body.
