What is Reticulate evolution: frequent introgressive hybridization among chinese hares (genus lepus ) revealed by analyses of multiple mitochondrial and nuclear DNA loci about?
## Background Interspecific hybridization may lead to the introgression of genes and genomes across species barriers and contribute to a reticulate evolutionary pattern and thus taxonomic uncertainties. Since several previous studies have demonstrated that introgressive hybridization has occurred among some species within __Lepus__, therefore it is possible that introgressive hybridization events also occur among Chinese __Lepus__ species and contribute to the current taxonomic confusion. ## Results Data from four mtDNA genes, from 116 individuals, and one nuclear gene, from 119 individuals, provides the first evidence of frequent introgression events via historical and recent interspecific hybridizations among six Chinese __Lepus__ species. Remarkably, the mtDNA of __L. mandshuricus__ was completely replaced by mtDNA from __L. timidus__ and __L. sinensis__. Analysis of the nuclear DNA sequence revealed a high proportion of heterozygous genotypes containing alleles from two divergent clades and that several haplotypes were shared among species, suggesting repeated and recent introgression. Furthermore, results from the present analyses suggest that Chinese hares belong to eight spe
