灵长类动物中最基本的谱系的起源和分化时间一直难以解决，主要是由于早期化石分类群的不完整采样。争论的主要来源与分子和化石估计之间的不一致有关：虽然没有超过56 Ma的冠灵长类化石，但大多数基于分子的估计将冠灵长类的起源延伸到白垩纪。在这里，我们提出了一个全面的灵长类动物的有丝分裂基因组学研究。我们组装了87个哺乳动物线粒体基因组，其中包括62个灵长类物种，代表了该命令的所有家庭。我们对11个线粒体基因组进行了新的测序，其中包括8只旧大陆猴和3只链霉菌。系统发育分析支持一个强大的拓扑结构，确认所有主要灵长类分支的单系性。与以前的有丝分裂基因组学研究相比，眼镜猴和猫猴相对于链鼻猴和猫猴的位置得到了很好的解决。为了提高我们对化石校准如何影响灵长类动物的年龄估计的理解，我们探索了灵长类动物和其他哺乳动物群体的17个化石校准的影响，并选择了一个校准子集来确定我们的有丝分裂基因组学树。的分歧日期估计Strepsirrhine/Haplorhine分裂支持冠灵长类动物的起源于晚白垩世，在74马左右。这一结果支持了灵长类起源的一个短导火索模型，即相对较少的时间之间的顺序和其主要分支的多样化的起源。这也表明，早期灵长类动物化石记录可能采样不足。
The origins and the divergence times of the most basal lineages within primates have been difficult to resolve mainly due to the incomplete sampling of early fossil taxa. The main source of contention is related to the discordance between molecular and fossil estimates: while there are no crown primate fossils older than 56 Ma, most molecule-based estimates extend the origins of crown primates into the Cretaceous. Here we present a comprehensive mitogenomic study of primates. We assembled 87 mammalian mitochondrial genomes, including 62 primate species representing all the families of the order. We newly sequenced eleven mitochondrial genomes, including eight Old World monkeys and three strepsirrhines. Phylogenetic analyses support a strong topology, confirming the monophyly for all the major primate clades. In contrast to previous mitogenomic studies, the positions of tarsiers and colugos relative to strepsirrhines and anthropoids are well resolved. In order to improve our understanding of how fossil calibrations affect age estimates within primates, we explore the effect of seventeen fossil calibrations across primates and other mammalian groups and we select a subset of calibrations to date our mitogenomic tree. The divergence date estimates of the Strepsirrhine/Haplorhine split support an origin of crown primates in the Late Cretaceous, at around 74 Ma. This result supports a short fuse model of primate origins, whereby relatively little time passed between the origin of the order and the diversification of its major clades. It also suggests that the early primate fossil record is likely poorly sampled.
