“…This indicates the occipito-pollicalis associated with bat wings is derived from cranial paraxial mesoderm that later migrates into the second pharyngeal arch of the embryo. This is mostly consistent with results based on the dissection of adult bats 15 . The coraco-cutaneus and humeropatagialis within the plagiopatagium were innervated by spinal nerves that constitute the brachial plexus: cervical nerves 5-8 (C5-C8) and thoracic nerve 1 (T1) (Fig.…”

“…To identify the developmental origin and the homology of these muscles, we examined the innervation pattern, which has been used as a criterion for establishing muscle homology because of its close link to myogenesis 15 . Our analysis revealed that both proximal and distal elements of the occipito-pollicalis were solely innervated by cranial nerve VII (the facial nerve), as well as the auricularis and the platysma (Fig.…”

“…In the present study, we revealed that the occipito-pollicalis of Miniopterus fuliginosus (family Miniopteridae), which is a member of Yangochiroptera, is solely innervated by cranial nerve VII. According to previous studies 13,15 , the muscle complex of Pteropus (family Pteropodidae), which belongs to Yinpterochiroptera, is innervated by not only cranial nerve VII but also cervical nerves. Also, in contrast to the simple organization of the ARTICLE occipito-pollicalis in Miniopterus, that in Pteropus is reportedly more complex, composed of several muscle bellies 13,15 .…”

We predict that the more complicated organization and innervation patterns of the occipito-pollicalis seen in pteropodid bats were brought about by the acquisition of unidentified novel developmental programs for establishing such anatomical features after they diverged from the common ancestor of Yangochiroptera or other lineages of Yinpterochiroptera.…”

The developmental basis of bat wing muscle

By acquiring wings, bats are the only mammalian lineage to have achieved flight. To be capable of powered flight, they have unique muscles associated with their wing. However, the developmental origins of bat wing muscles, and the underlying molecular and cellular mechanisms are unknown. Here we report, first, that the wing muscles are derived from multiple myogenic sources with different embryonic origins, and second, that there is a spatiotemporal correlation between the outgrowth of wing membranes and the expansion of wing muscles into them. Together, these findings imply that the wing membrane itself may regulate the patterning of wing muscles. Last, through comparative gene expression analysis, we show Fgf10 signalling is uniquely activated in the primordia of wing membranes. Our results demonstrate how components of Fgf signalling are likely to be involved in the development and evolution of novel complex adaptive traits.

Molecular Evolution Inferred from Immunological Cross-reactivity of Immunoglobulin G among Chiroptera and Closely Related Species

Abstract:We examined the relationships between Megachiroptera and Microchiroptera, and between Chiroptera and other closely related species by the cross-reactivity of immunoglobulin epitopes. Rabbit polyclonal antibody to bat IgG was used for determining the cross-reactivity by a competitive ELISA method. Megachiroptera and Microchiroptera showed high cross-reactivity, over 95.3%, with each other. However, primates and insectivores showed very low cross-reactivity, 8.6 to 20.2% and 5.3 to 12.7%, respectively. These results suggest that suborders of Chiroptera are monophyletic and Chiroptera have a relatively closer relationship to primates than to insectivores.

A comparative morphometric analysis of isolated proximal and intermediate phalanges attributed to the paromomyids Ignacius graybullianus and Phenacolemur simonsi was undertaken to test the hypothesis that these fossil phalanges exhibit evidence of a dermopteran-like interdigital patagium. Linear dimensions were collected for the fossil phalanges and a comparative sample of associated proximal and intermediate phalanges representing extant tree squirrels, tree shrews, dermopterans (colugos), gliding rodents and marsupials, and prosimian primates. Quantitative data indicate that the proximal and intermediate phalanges of paromomyids are most similar in their overall shape to those of the dermopteran Cynocephalus. The proximal phalanges of paromomyids and colugos possess well-developed flexor sheath ridges and broad, high shafts, whereas the intermediate phalanges of these taxa are most similar to one another in their trochlear morphology. Discriminant analysis indicates that all of the paromomyid intermediate phalanges resemble those from colugo toes more so than those from colugo fingers. Moreover, the relative length and midshaft proportions of both the proximal and intermediate phalanges of paromomyids closely resemble those of several squirrels that lack an interdigital patagium. The following conclusions are drawn from this study: 1) paromomyids share a number of derived phalangeal features with modern dermopterans that may be indicative of a phylogenetic relationship between them, 2) existing intermediate phalanges of paromomyids are inconsistent with the "mitten gliding" hypothesis because they do not possess the distinctive length and midshaft proportions characteristic of colugo manual intermediate phalanges, and 3) paromomyids share with colugos and the scaly-tailed squirrel Anomalurus several aspects of phalangeal morphology functionally related to frequent vertical clinging and climbing on large-diameter arboreal supports.
