Cases of convergent evolution - where different lineages have evolved similar traits independently - are common and have proven central to our understanding of selection. Yet convincing examples of adaptive convergence at the sequence level are exceptionally rare [1]. The motor protein Prestin is expressed in mammalian outer hair cells (OHCs) and is thought to confer high frequency sensitivity and selectivity in the mammalian auditory system [2]. We previously reported that the Prestin gene has… Expand
Contrasting patterns of adaptive sequence convergence among echolocating mammals.
TLDR
The results indicate that the convergent evolution of Cdh23 was likely driven by selection for hearing above a certain frequency threshold, and the contrasting patterns of convergence between the two bat suborders and dolphin in all auditory genes studied thus far suggest echolocation may have evolved independently in the Yinpterochiroptera and Yangochioptera.

Prestin Shows Divergent Evolution Between Constant Frequency Echolocating Bats
TLDR
The reconstructed Prestin gene tree and amino acid tree showed that P. parnellii did not group together with Old World horseshoe and leaf-nosed bats, but rather clustered within its true sister species, and found no evidence of positive selection in the branch leading to the genus of Pteronotus. Expand
Parallel signatures of sequence evolution among hearing genes in echolocating mammals: an emerging model of genetic convergence
TLDR
Signatures of sequence convergence and molecular adaptation in two additional hearing genes suggest that the acquisition of high-frequency hearing has involved multiple loci, contrasting with purifying selection on non-echolocating bats. Expand
Functional Effects of a Retained Ancestral Polymorphism in Prestin.
TLDR
The study not only reveals sophisticated molecular basis of echolocation in bats, but also calls for caution in the inference of molecular convergence in species experiencing rapid radiation. Expand
Genome-wide signatures of convergent evolution in echolocating mammals
TLDR
This first attempt to detect genome-wide convergent sequence evolution across divergent taxa reveals the phenomenon to be much more pervasive than previously recognized. Expand
A functional enrichment test for molecular convergent evolution finds a clear protein-coding signal in echolocating bats and whales
TLDR
A generalizable test is developed that offers a resounding “yes” to both extensively debated questions about molecular convergence and how much genomic molecular convergence contributes to convergent phenotypic evolution, such as echolocation in bats and whales. Expand
Parallel Evolution of Auditory Genes for Echolocation in Bats and Toothed Whales
TLDR
It is revealed that positive selection, parallel evolution, and perhaps co-evolution and gene expression affect multiple hearing genes that play different roles in audition, including voltage and bundle motility in cochlear amplification, nerve transmission, and brain function. Expand
Phylogeny, Genes, and Hearing: Implications for the Evolution of Echolocation in Bats
TLDR
In this chapter, the consensus and conflict regarding bat evolutionary relationships is explored based on key phylogenetic studies conducted over the past 15 years, and the potential molecular sensory trade-offs between echolocation, vision, olfaction, and taste are explored. Expand
Evidence of Echolocation in the Common Shrew from Molecular Convergence with Other Echolocating Mammals.
TLDR
Evidence at the molecular level that thecommon shrew echolocate is given and novel insights into the convergent evolution between the common shrew and bats and dolphins are provided. Expand
Parallel Evolution of KCNQ4 in Echolocating Bats
TLDR
This study obtains the coding regions of KCNQ4 from 15 species of bats, including echolocating bats that have higher frequency hearing and non-echolocatingbats that have the same ability as most other species of mammals, and identifies five parallel evolved sites in echoling bats belonging to both suborders.

TLDR
The extensive adaptive radiation in echolocation call design is shaped largely by ecology, showing how perceptual challenges imposed by the environment can often override phylogenetic constraints. Expand
The hearing gene Prestin reunites echolocating bats
TLDR
The study of a hearing gene in bats strongly implicates Prestin in the evolution of echolocation, and suggests independent evolution of high-frequency hearing in bats, which highlights the potential problems of extracting phylogenetic signals from functional genes that may be prone to convergence.

TLDR
Results indicate that nonneutral convergent molecular evolution in mitochondria can occur at a scale and intensity far beyond what has been documented previously, and they highlight the vulnerability of standard phylogenetic methods to the presence of non neutral convergent sequence evolution.
