E.S. was supported by a fellowship from the Josephine De Karman
Fellowship Trust and an Alden H. Miller Fellowship from the Museum of
Vertebrate Zoology. We thank the DAAD, whose partial PROMOS scholarship
made it possible for D.D., J.P. and J.F. to work within the project.
This study was supported in part by subsidy funding to the Okinawa
Institute of Science and Technology (OIST). We thank Matthew Knope and
Mel Johansen for logistical assistance, Sven Künzel for sequencing our
