TI - Development of bat flight: morphologic and molecular evolution of bat wing
PG - 6581-6
AB - The earliest fossil bats resemble their modern counterparts in possessing greatly
elongated digits to support the wing membrane, which is an anatomical hallmark of
powered flight. To quantitatively confirm these similarities, we performed a
morphometric analysis of wing bones from fossil and modern bats. We found that
the lengths of the third, fourth, and fifth digits (the primary supportive
elements of the wing) have remained constant relative to body size over the last 50 million years. This absence of transitional forms in the fossil record led us to look elsewhere to understand bat wing evolution. Investigating embryonic
development, we found that the digits in bats (Carollia perspicillata) are
initially similar in size to those of mice (Mus musculus) but that, subsequently,
bat digits greatly lengthen. The developmental timing of the change in wing digit
length points to a change in longitudinal cartilage growth, a process that
depends on the relative proliferation and differentiation of chondrocytes. We
found that bat forelimb digits exhibit relatively high rates of chondrocyte
proliferation and differentiation. We show that bone morphogenetic protein 2
(Bmp2) can stimulate cartilage proliferation and differentiation and increase
digit length in the bat embryonic forelimb. Also, we show that Bmp2 expression
and Bmp signaling are increased in bat forelimb embryonic digits relative to
mouse or bat hind limb digits. Together, our results suggest that an
up-regulation of the Bmp pathway is one of the major factors in the developmental
elongation of bat forelimb digits, and it is potentially a key mechanism in their
evolutionary elongation as well.

TI - Integrated fossil and molecular data reconstruct bat echolocation.
PG - 6241-6
AB - Molecular and morphological data have important roles in illuminating
evolutionary history. DNA data often yield well resolved phylogenies for living
taxa, but are generally unattainable for fossils. A distinct advantage of
morphology is that some types of morphological data may be collected for extinct and extant taxa. Fossils provide a unique window on evolutionary history and may preserve combinations of primitive and derived characters that are not found in
extant taxa. Given their unique character complexes, fossils are critical in
documenting sequences of character transformation over geologic time and may
elucidate otherwise ambiguous patterns of evolution that are not revealed by
molecular data alone. Here, we employ a methodological approach that allows for
the integration of molecular and paleontological data in deciphering one of the
most innovative features in the evolutionary history of mammals-laryngeal
echolocation in bats. Molecular data alone, including an expanded data set that
includes new sequences for the A2AB gene, suggest that microbats are paraphyletic
but do not resolve whether laryngeal echolocation evolved independently in
different microbat lineages or evolved in the common ancestor of bats and was
subsequently lost in megabats. When scaffolds from molecular phylogenies are
incorporated into parsimony analyses of morphological characters, including
morphological characters for the Eocene taxa Icaronycteris, Archaeonycteris,
Hassianycteris, and Palaeochiropteryx, the resulting trees suggest that laryngeal
echolocation evolved in the common ancestor of fossil and extant bats and was
subsequently lost in megabats. Molecular dating suggests that crown-group bats
last shared a common ancestor 52 to 54 million years ago.
