Abstract

The limited ranges of the wild progenitors of many of the primary European domestic species point to their origins further east in Anatolia or the fertile crescent. The wild ox (Bos primigenius), however, ranged widely and it is unknown whether it was domesticated within Europe as one feature of a local contribution to the farming economy. Here we examine mitochondrial DNA control-region sequence variation from 392 extant animals sampled from Europe, Africa and the Near East, and compare this with data from four extinct British wild oxen. The ancient sequences cluster tightly in a phylogenetic analysis and are clearly distinct from modern cattle. Network analysis of modern Bos taurus identifies four star-like clusters of haplotypes, with intra-cluster diversities that approximate to that expected from the time depth of domestic history. Notably, one of these clusters predominates in Europe and is one of three encountered at substantial frequency in the Near East. In contrast, African diversity is almost exclusively composed of a separate haplogroup, which is encountered only rarely elsewhere. These data provide strong support for a derived Near-Eastern origin for European cattle.

摘要

许多主要欧洲家养物种的野生祖先分布范围有限,这表明它们起源于更东部的安纳托利亚或肥沃新月地带。然而,野牛(原牛)分布广泛,目前尚不清楚它是否是在欧洲本土被驯化,作为当地对农耕经济贡献的一个特征。在这里,我们研究了从欧洲、非洲和近东地区采集的392只现存动物的线粒体DNA控制区序列变异,并将其与四只已灭绝的英国野牛的数据进行比较。在系统发育分析中,古代序列紧密聚类,且明显不同于现代牛。对现代家牛的网络分析识别出四个单倍型的星状聚类,聚类内的多样性与家养历史时间深度预期的相近。值得注意的是,其中一个聚类在欧洲占主导地位,并且是在近东地区大量出现的三个聚类之一。相比之下,非洲的多样性几乎完全由一个单独的单倍群组成,在其他地方很少见。这些数据为欧洲牛起源于近东地区提供了有力支持。
