古罗马是一个拥有约 7000 万居民的帝国的首都，但人们对古罗马人的遗传学知之甚少。在这里，我们展示了来自罗马及其周边地区 29 个考古遗址的 127 个基因组，跨越过去 12,000 年。我们观察到两个主要的史前祖先转变：一个是随着农业的引入而发生的，另一个是在铁器时代之前的。到罗马建立时，该地区的基因组成接近现代地中海人口的基因组成。在帝国时期，罗马人口接受了来自近东的净移民，随后来自欧洲的遗传贡献有所增加。这些血统的转变反映了罗马的地缘政治归属，并伴随着明显的个体间多样性，反映了来自地中海、欧洲和北非的基因流动。
Ancient Rome was the capital of an empire of similar to 70 million inhabitants, but little is known about the genetics of ancient Romans. Here we present 127 genomes from 29 archaeological sites in and around Rome, spanning the past 12,000 years. We observe two major prehistoric ancestry transitions: one with the introduction of farming and another prior to the Iron Age. By the founding of Rome, the genetic composition of the region approximated that of modern Mediterranean populations. During the Imperial period, Rome's population received net immigration from the Near East, followed by an increase in genetic contributions from Europe. These ancestry shifts mirrored the geopolitical affiliations of Rome and were accompanied by marked interindividual diversity, reflecting gene flow from across the Mediterranean, Europe, and North Africa.
