Genome-wide signatures of complex introgression and adaptive evolution in the big cats

Abstract

Big cat genomes reveal a history of interspecies admixture and adaptive evolution of genes underlying development and sensory perception.

Evolution of morphological integration in the skull of Carnivora (Mammalia): Changes in Canidae lead to increased evolutionary potential of facial traits

“…; Figueiró et al. ; Zhou et al. ) producing a tree topology that best summarized current knowledge of phylogenetic relationships between species.…”

“…Phylogenetic relationships were compiled from a host of different sources (e.g., Arnold et al 2010;Nyakatura and Bininda-Emonds 2012;Slater et al 2012;Li et al 2015;Figueiró et al 2017;Zhou et al 2017) producing a tree topology that best summarized current knowledge of phylogenetic relationships between species. Because some of the methods used here require a dated phylogeny, we estimated branch lengths via maximumlikelihood using cytochrome-B data downloaded from GenBank.…”

Comparative analysis of corrected tiger genome provides clues to their neuronal evolution

“…The usage of corrected tiger and leopard coding genome, a large number of orthologs, and five 406 different evolutionary analysis in this study, makes the evolutionary assessments more reliable, and 407 was also successful in revealing the signatures of adaptive divergence in felids, Panthera and tiger 408 lineages. Previous reports identified evolutionary adaptations in genes related to muscle strength, 409 hypercarnivorous diet, sensory perception, and craniofacial and limb development in the 410 Panthera/Felidae lineage 1,5,34,39 . Similar categories were also found to be adaptively evolved in the 411 Panthera/Felidae lineage in this study.…”

“…Comparative genomic analysis was performed to gain insights into the evolution of tiger with several 185 other mammalian species. Tiger is a prominent member of the Panthera genus, which is a fast 186 evolving group that has undergone recent radiation with rapid functional diversification [34][35][36] . Thus, novo assembler or by the read correction tools (Supplementary Text S1) [10][11][12][13][14][15] .…”

“…other studies. For example,Figueiro et al, 2017 identified that the ESRP1 gene, important for 381 craniofacial robustness, has a positively selected I298Y substitution in jaguar34 . This substitution was 382 found to be positively selected in jaguar due to the presence of "I" in the respective ortholog in 383 tiger, which was a result of single nucleotide error in the tiger genome assembly (Supplementary 384 and 4).…”
