Locked within our genetic code are the histories of our genes and the genes of our ancestors. Deciphering a population's history from genetic data often involves lengthy investigations of many loci for many individuals. We test hypothetical population histories of the Thule expansion using a new coalescent simulation method that uses little more than mitochondrial haplogroup data. This new methodology rejects a severe bottleneck at expansion and reveals the range of probable population histories on which to focus future research.
我们的基因密码中锁存着我们自身基因以及祖先基因的历史。从基因数据解读一个种群的历史往往涉及对众多个体的许多基因座进行漫长的研究。我们使用一种新的溯祖模拟方法来检验图勒扩张的假设种群历史，该方法所使用的不过是线粒体单倍群数据而已。这种新方法否定了扩张时存在严重瓶颈的说法，并揭示了一系列可能的种群历史，以便为未来的研究指明方向。
