Phylogenetics: Bats United, Microbats Divided
نویسنده
چکیده
Phylogenetic analyses on four new bat genomes provide convincing support for the placement of bats relative to other placental mammals, suggest that microbats are an unnatural group, and have important implications for understanding the evolution of echolocation.

Microbat paraphyly and the convergent evolution of a key innovation in Old World rhinolophoid microbats.
Molecular phylogenies challenge the view that bats belong to the superordinal group Archonta, which also includes primates, tree shrews, and flying lemurs. Some molecular studies also challenge microbat monophyly and instead support an alliance between megabats and representative rhinolophoid microbats from the families Rhinolophidae (horseshoe bats, Old World leaf-nosed bats) and Megadermatida...
متن کاملBase compositional bias and phylogenetic analyses: a test of the "flying DNA" hypothesis.
Phylogenetic methods can produce biased estimates of phylogeny when base composition varies along different lineages. Pettigrew (1994, Curr. Biol. 4:277-280) has suggested that base composition bias is responsible for the apparent support for the monophyly of bats (Chiroptera: megabats and microbats) from several different nuclear and mitochondrial genes. Pettigrew's "flying DNA" hypothesis mak...
متن کاملIntegrated fossil and molecular data reconstruct bat echolocation.
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 co...
متن کاملParallel and Convergent Evolution of the Dim-Light Vision Gene RH1 in Bats (Order: Chiroptera)
Rhodopsin, encoded by the gene Rhodopsin (RH1), is extremely sensitive to light, and is responsible for dim-light vision. Bats are nocturnal mammals that inhabit poor light environments. Megabats (Old-World fruit bats) generally have well-developed eyes, while microbats (insectivorous bats) have developed echolocation and in general their eyes were degraded, however, dramatic differences in the...
متن کاملThe hearing gene Prestin unites echolocating bats and whales
Echolocation is a sensory mechanism for locating, ranging and identifying objects which involves the emission of calls into the environment and listening to the echoes returning from objects [1]. Only microbats and toothed whales have acquired sophisticated echolocation, indispensable for their orientation and foraging [1]. Although the bat and whale biosonars originated independently and diffe...
