INSECT PHYLOGENOMICS. Comment on "Phylogenomics resolves the timing and pattern of insect evolution".

چکیده
Misof et al. (Reports, 7 November 2014, p. 763) used a genome-scale data set to estimate the relationships among insect orders and the time scale of their evolution. Here, we reanalyze their data and show that their method has led to systematic underestimation of the evolutionary time scale. We find that key insect groups evolved up to 100 million years earlier than inferred in their study.

INSECT PHYLOGENOMICS. Response to Comment on "Phylogenomics resolves the timing and pattern of insect evolution".
Tong et al. comment on the accuracy of the dating analysis presented in our work on the phylogeny of insects and provide a reanalysis of our data. They replace log-normal priors with uniform priors and add a "roachoid" fossil as a calibration point. Although the reanalysis provides an interesting alternative viewpoint, we maintain that our choices were appropriate.
متن کاملComment on “Phylogenomics resolves the timing and pattern of insect evolution”
I nsects are the most diverse group of animals on Earth, occupying a broad range of niches across ecosystems. However, many insect groups have a poor fossil record, meaning that the early evolution of hexapod orders remains shrouded in mystery (1). For this reason, studies of insect diversification, the timing of evolutionary innovations, and the arthropod phylogeny rely on molecular date estim...
متن کاملInsect Phylogenomics: Exploring the Source of Incongruence Using New Transcriptomic Data
The evolution of the diverse insect lineages is one of the most fascinating issues in evolutionary biology. Despite extensive research in this area, the resolution of insect phylogeny especially of interordinal relationships has turned out to be still a great challenge. One of the challenges for insect systematics is the radiation of the polyneopteran lineages with several contradictory and/or ...
متن کاملRunning Head: HIGHLY MULTIPLEXED AMPLICON-BASED PHYLOGENOMICS 1 Title: HiMAP: robust Phylogenomics from Highly Multiplexed Amplicon sequencing
15 High-throughput sequencing has fundamentally changed how molecular phylogenetic datasets 16 are assembled, and phylogenomic datasets commonly contain 50-100-fold more loci than those 17 generated using traditional Sanger-based approaches. Here, we demonstrate a new approach for 18 building phylogenomic datasets using single tube, highly multiplexed amplicon sequencing, 19 which we name HiMAP...
متن کاملPhylogenomics resolves the timing and pattern of insect evolution.
Insects are the most speciose group of animals, but the phylogenetic relationships of many major lineages remain unresolved. We inferred the phylogeny of insects from 1478 protein-coding genes. Phylogenomic analyses of nucleotide and amino acid sequences, with site-specific nucleotide or domain-specific amino acid substitution models, produced statistically robust and congruent results resolvin...
