摘要: Summary The evolutionary history of the wolf-like canids genus Canis has been heavily debated, especially regarding number distinct species and their relationships at population level [ 1 , 2 3 4 5 6 ]. We assembled a dataset 48 resequenced genomes spanning all members except black-backed side-striped jackals, encompassing global diversity seven extant canid lineages. This includes eight new genomes, including first Ethiopian wolf (Canis simensis), one dhole (Cuon alpinus), two East African hunting dogs (Lycaon pictus), Eurasian golden jackals aureus), Middle Eastern gray wolves lupus). between wolf, jackal were resolved. highlight role interspecific hybridization in evolution this charismatic group. Specifically, we find gene flow ancestors dog admixture coyote latrans), jackal, wolf. Additionally, report from to suggesting that originated through these species. Finally, hypothesize coyotes carry genetic material derived “ghost” basal lineage.
