We screened a total of 841 Y‐chromosomes representing 36 human populations of wide geographical distribution for the presence of a Y‐specific Alu insert (YAP+ chromosomes). The Alu element was found in 77 cases. We tested 5 biallelic and 8 polyallelic markers in 70 out of the 77 YAP+ chromosomes. We could identify the existence of a hierarchical and chronological structuring of ancestral and derived YAP+ lineages, giving rise to 4 haplogroups, 14 subhaplogroups and 60 haplotypes. Moreover, we propose a monophyletic origin for each one of the YAP+ lineages. Out‐of‐Africa and out‐of‐Asia models have been suggested to explain the origin and evolution of ancestral and derived YAP+ elements. We analyze the evidence supporting these two hypotheses, and we conclude that the information available does not allow one to decide between the out‐of‐Asia or out‐of‐Africa models.
