While it is important not to overstate the power of archeological inference from genetic data, some previously widespread conjectures are inevitably contradicted with the addition of new information. Conjectures regarding domesticated cattle that fall into this category include a single domestication event with the development of Bos indicus breeds from earlier Bos taurus domesticates; the domestication of a third type of cattle in Africa having an intermediate morphology between the two taxa; and the special status of the Jersey breed as a European type with some exotic influences. In reality, a wideranging survey of the genetic variation of modern cattle reveals that they all derive from either zebu or taurine progenitors or are hybrids of the two. The quantitative divergence between Bos indicus and Bos taurus strongly supports a predomestic separation; that between African and European taurines also suggests genetic input from native aurochsen populations on each continent. Patterns of genetic variants assayed from paternally, maternally, and biparentally inherited genetic systems reveal that extensive hybridization of the two subspecies is part of the ancestry of Northern Indian, peripheral European, and almost all African cattle breeds. In Africa, which is the most extensive hybrid zone, the sexual asymmetry of the process of zebu introgression into native taurine breeds is strikingly evident. © 1998 Wiley-Liss, Inc.
