摘要：Comparing the neural transcriptomes of 5 phylogenetically independent pairs of monogamous and nonmonogamous vertebrates, Young et al. (1) claim to have found evidence for “a universal transcriptomic mechanism underlying the evolution of monogamy in vertebrates. They state that “while evolutionary divergence time between species or clades did not explain gene expression similarity, characteristics of the mating system correlated with neural gene expression patterns. Given the deep divergences among these clades, parallel evolution at the transcriptomic scale is highly unlikely, prompting us to reexamine their results. We followed a previous study (2) to compute the distance between each pair of transcriptomes on the basis of expression-level differences of orthologous genes and build a neighboring-joining tree of the 10 transcriptomes. Young et al.’s (1) conclusion means that the transcriptomes from the 5 monogamous species should be clustered in the tree, in exclusion of those from the nonmonogamous.
