渐渗杂交现在被认为是一种普遍的现象，但它在进化中的作用仍然存在争议。在这里，我们使用最新的参考基因组组装调查的系统发育关系和渐渗在一个医学上重要的一组非洲热带蚊子的兄弟物种。我们已经确定了正确的物种分支顺序，以解决有争议的遗传学问题，并表明导致人类疟疾主要媒介的谱系是第一批分裂的。这些疟疾病媒之间普遍存在的常染色体渐渗意味着只有一小部分基因组（主要在X染色体上）没有跨越物种界限。我们的研究结果表明，性状增强矢量的能力可能会通过种间基因流，包括非姐妹物种之间获得。
Introgressive hybridization is now recognized as a widespread phenomenon, but its role in evolution remains contested. Here we use newly available reference genome assemblies to investigate phylogenetic relationships and introgression in a medically important group of Afrotropical mosquito sibling species. We have identified the correct species branching order to resolve a contentious phylogeny, and show that lineages leading to the principal vectors of human malaria were among the first to split. Pervasive autosomal introgression between these malaria vectors means that only a small fraction of the genome, mainly on the X chromosome, has not crossed species boundaries. Our results suggest that traits enhancing vectorial capacity may be gained through interspecific gene flow, including between non-sister species.
