• Resumen

  • The article focuses on the anatomy of flight and echolocation, sightless navigation, in bats, and uses fossil records to trace and describe their evolution. The author describes how mapping the distribution of certain traits in bat fossils is used to test hypotheses about which evolved first, flight or echolocation. She also explains some of the mysteries that remain, including the lack of fossil records for the earliest bats and their place within the lineage known as Laurasiatheria.
