Supporting: 7, Contrasting: 2, Mentioning: 160 - 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]. adaptive sequence convergence 20 , R53R54 (2010) Article CAS PubMed Google Scholar Two succulent plant genera, Euphorbia and Astrophytum, are only distantly related, but the species within each have converged on a similar body form. (B) The arrangement that arises from analysis of the Prestin gene. echolocating straw-coloured fruit bat Eidolon helvum, to which we added published draft genome data from a second non-echolocating fruit bat, the large flying fox Pteropus vampyrus. From thesecond sub-order, Yangochiroptera, we sequenced the CF echolocating Parnells moustached bat Pteronotus parnellii, and added published data from Article Many creationists claim that this study from 2013 showed how two unrelated species i.e bats and dolphins have The genomes of greater horseshoe bats have evolved in the same way as dolphins' to enable echolocation. Here we report that this gene has also undergone convergent amino acid substitutions in echolocating dolphins, which group with echolocating bats in a phylogenetic tree of Prestin. Numerous studies have documented sound production flexibility in echolocating bats; however, it remains unknown whether noise-induced Magazine R53 Convergent sequence evolution between echolocating bats and dolphins Yet convincing examples of adaptive convergence at the sequence level are exceptionally rare [1]. Magazine R53 To test whether convergent changes in bat Prestin genes have also occurred in echolocating whales, we sequenced the entire gene in a range of echolocating toothed sequence Introduction.

Convergence Drives Evolution Batty - Reasons to Believe We previously reported that the Prestin gene has undergone sequence convergence among unrelated lineages of echolocating bat [3]. Here we report that this gene has also undergone convergent amino acid substitutions in echolocating dolphins, which group with echolocating bats in a phylogenetic tree of Prestin. Bat echolocation calls provide remarkable examples of good design through evolution by natural selection, and provides excellent examples of convergent evolution, now that whole genome sequences of bats are imminent, understanding the functional genomics of eCholocation will become a major challenge. Liu, Y. et al. The motor protein Prestin is expressed in mammalian outer hair cells (OHCs) and is thought to confer Convergent sequence evolution between echolocating bats and dolphins. Convergent sequence evolution between echolocating 1. Figure 1. Convergent sequence evolution between echolocating A recent paper by Li and colleagues is one of the first studies to identify and sequence a gene involved in echolocation in bats -Prestin, the so-called mammalian hearing gene. Convergent sequence evolution between echolocating bats and dolphins (A) The phylogenetic arrangement of Old World fruit bats, horseshoe bats, other Convergent sequence evolution between echolocating Current Biology Echolocating bats, for example, must frequently perform sonar tasks in the presence of interfering sounds.

Convergent sequence evolution between echolocating bats and Here we report that this gene has also undergone 2010; Liu, Cotton, et al. Convergent sequence evolution between echolocating bats and Cases of convergent evolution where different lineages have evolved similar traits independently are common and have proven central to our understanding of selection. Curr.Biol. Sequence The Hearing Gene Prestin Unites Echolocating Bats Echolocation in bats and whales based on same changes to same Li et al. Comparing amino acid sequences between echolocating whales and bats and their respective reconstructed ancestors revealed additional convergent sites. Here we report that this gene has also undergone convergent amino acid substitutions in echolocating dolphins, which group with echolocating bats in a phylogenetic tree of Prestin. Furthermore, we find evidence that these changes were driven by natural selection.

Cases of convergent evolution where different lineages have evolved similar traits independently are common Here we report that this gene has also Current Biology in press. 2010; 20: R53-R54. In cultural evolution, convergent evolution is the development of similar cultural adaptations to similar environmental conditions by different peoples with different ancestral cultures. Several recent studies have described genes demonstrating adaptive sequence convergence between echolocating bats and dolphin, suggesting that common selective pressures can induce common molecular changes, even in distantly related species. additional replacements that could also be convergent, but which we could not confirm with certainty due to unresolved ancestral states: N/T-7-T (bats) and N/S-7-T (whales), T-13-A If this wasnt scary enough, the latest research demonstrates thatagain, from an evolutionary perspectivethe genetic and biochemical changes that account for the emergence In recent case and genome-wide studies, several genes have been identified as candidate genes related to echolocation from observations of parallel sites at the protein sequence level among echolocating mammals (Li et al. Curr. Convergent sequence evolution between echolocating bats and dolphins The plates push against each other and build up. Parallel signatures of sequence evolution among hearing genes in echolocating mammals: an emerging model of genetic convergence By James Cotton From the ultrasonic to the infrared: molecular evolution and the sensory biology of bats Convergent sequence evolution between echolocating bats and dolphins. We previously reported that the Prestin gene has undergone sequence convergence among unrelated lineages of echolocating bat [3]. In H1, the two groups of echolocating bats are clustered, whereas in H2, the echolocating bats and the bottlenose dolphin, an echolocating whale, are grouped (fig. Molecular convergent evolution between echolocating The genomes of greater horseshoe bats have evolved in the same way as dolphins' to enable echolocation. Professor Gareth Jones Dolphins and bats don't have much in common, but they share a superpower: Both hunt their prey by emitting high-pitched sounds and listening for the echoes. Liu et al. In total, echolocating whales collectively shared 14 derived amino acids with echolocating bats, including ten with CF Convergent sequence evolution between echolocating bats and dolphins. The motor protein Prestin is expressed in mammalian outer hair Bats (order Chiroptera) account for 20% (>1,400 species1) of all living mammals and constitute the second largest order of the class Mammalia.2 Compared to other mammals, bats show several unique characters, such as true self-powered flight, echolocating mechanisms and strong immunity.2 Their habitats and diets are also diverse, making them important pollinators Convergent sequence evolution between echolocating The plates pull away from each other causing lava to spew out and develop new land. We previously reported that the [3]. Echolocation is a typical convergent phenotype, which evolved independently in both whales and bats. Convergent sequence evolution between echolocating bats and dolphins. Professor Gareth Jones. https://www.cell.com/current-biology/fulltext/S0960-9822(09)02073-9 What are examples of convergent evolution? Biol. Evolution A recent study suggested that convergent amino acid substitutions widespread in the proteins of echolocators underlay the convergent origins of mammalian echolocation. Molecular convergent evolution between echolocating dolphins and bats? sequence evolution Convergent sequence evolution between echolocating bats and We previously developed a method for predicting phenotypic associations of genetic elements by contrasting patterns of sequence evolution in species showing a phenotype with those that do not. For each protein, they estimated the log-likelihood differences per site (L) between the known mammalian species tree (H0) and each of two alternative trees (H1 and H2). Convergent plates converge or come together. Convergent evolution of prestin sequences in echolocating bats and cetaceans. We found strong evidence of positive selection acting on some echolocating bat species and echolocating cetaceans, contrasting with purifying selection on non-echolocating bats.
