Autor: T. Alexander Dececchi, Hans C.E. Larsson, Michael B. Habib

Publikováno v: PeerJ, Vol 4, p e2159 (2016)

Background: Powered flight is implicated as a major driver for the success of birds. Here we examine the effectiveness of three hypothesized pathways for the evolution of the flight stroke, the forelimb motion that powers aerial locomotion, in a terr
