Evolutionary History

  • Delicate bat fossils are quite rare, especially the Megachiroptera (only 2 fossils older than Pleistocene) (Baker et al 1991)
  • Considerable debate among researchers in 1990's regarding relationships between mega and micro chiropterans
    • Descended from a common ancestor (monophyletic) (Thewissen & Babcock 1991 )
    • Evolved from two separate ancestors (Pettigrew 1995, Pettigrew et al 1989)
  • Most recent studies support bats evolving from a single common ancestor. (Simmons & Conway 1997) (Nikaido et al 2000)
  • Divergence of two suborders of bats dates to between 72-61 million years ago (Kirsch et al 1995) or slightly younger at 58 million years ago.(Nikaido et al 2000).
  • Icaronycteris recognized as early microchiropteran bat - from 50 million year old rocks in North America and Europe (Simmons et al 2008)
  • Archaeopteropus is a known early megachiropteran dating to 30 million years ago from Italy. (Oligocene)
  • The pteropid bat family arose in Australo-Pacific or south-east Asia in 23-14 million years ago (Early Miocene) (Kirsch et al 1995)
  • The pteropid family now occupies Old World tropics of Africa, Asia, and Indo-Australia. (Hill & Smith 1988)
