Science 272:738–741 Chapter 2 Time’s Arrow in the Evolutionary Development of Bat Flight Rick A. Adams and Jason B. Shaw Abstract Conceptualizing the evolution of flight in mammals is confounded by a lack of empirical evidence. In this chapter, we quantify functional ontogeny to model the evolution of flight in bats to fill in transitional gaps between a hypothetical nonvolant ancestor and volant descendents. Our data thus far indicate that bats evolved flapping flight mechanics directly with no gliding intermediate forms and that bats most likely evolved from a terrestrial, rather than arboreal, ancestor.

Conversely, for flapping flight, formation of a dactylopatagium would be favored for maximizing power stroke, turning ability, and orientation control. 9 Synthesis Time’s arrow is a concept developed by astronomer Arthur Eddington in 1927 to describe the past to present direction of time (Carroll 2010). A. B. 2 Concordance hypothesis between developmental stages (based upon data gathered on C. perspicillata) and evolutionary stages (based on molecular and fossil evidence) Error bars for estimated evolutionary events may comprise several million years important insights into how, when, and why key morphological and behavioral innovations transpired (Hall et al.
