A full understanding of primate morphological and genomic evolution requires the identification of their closest living relative. In order to resolve the ancestral relationships among primates and their closest relatives, we searched multispecies genome alignments for phylogenetically informative rare genomic changes within the superordinal group Euarchonta, which includes the orders Primates, Dermoptera (colugos), and Scandentia (treeshrews). We also constructed phylogenetic trees from 14… Expand
Conserved sequences identify the closest living relatives of primates
TLDR
The phylogeny showed Cercopithecinae to have low levels of nucleotide divergence, especially for Papionini, and gibbons to have a high rate of divergence, and the MCMCtree comprehensively updated divergence dates of early evolution of Primatomorpha and Primates. Expand
A Molecular Phylogeny of Living Primates
TLDR
The resolution of the primate phylogeny provides an essential evolutionary framework with far-reaching applications including: human selection and adaptation, global emergence of zoonotic diseases, mammalian comparative genomics, primate taxonomy, and conservation of endangered species. Expand
Estimating the phylogeny and divergence times of primates using a supermatrix approach
TLDR
This work presents an up-to-date, comprehensive estimate of the structure and tempo of primate evolutionary history, using Bayesian phylogenetic methods to analyze data supermatrices from 219 species across 67 genera and 3 nuclear genes from 26 genera. Expand
Resolution among major placental mammal interordinal relationships with genome data imply that speciation influenced their earliest radiations
TLDR
The narrow temporal window within which some placental divergences took place suggests that inconsistencies and limited resolution of the mammalian tree may have their natural explanation in speciation processes such as lineage sorting, introgression from species hybridization or hybrid speciation. Expand
Genomic analysis reveals hidden biodiversity within colugos, the sister group to primates
TLDR
Large genetic differences between many geographically isolated populations that may result in a >300% increase in the number of recognized colugo species are identified and conservation units to mitigate future losses of this enigmatic mammalian order are identified. Expand
Molecular Evidence of Primate Origins and Evolution
Molecular data have become an important source of evidence on primate evolutionary history, particularly when the fossil evidence is limited or lacking. The most recent molecular phylogenetic studiesExpand

TLDR
This Perspective lifts the hood on the conventional tree-like representation of the phylogenetic relationships between species, to expose the population-genetic processes that operate along its branches and discusses remaining challenges and future prospects at this nexus of phylogenetics, population genetics, and genomics. Expand
Primate phylogenomics uncovers multiple rapid radiations and ancient interspecific introgression
TLDR
New reference genome assemblies for three Old World Monkey species are presented and strongly asymmetric patterns of gene tree discordance around specific branches are used to identify multiple instances of introgression between ancestral primate lineages. Expand
Impact of genomics on the understanding of microbial evolution and classification: the importance of Darwin's views on classification.
TLDR
Multiple CSIs and CSPs have been identified for successive nested clades providing reliable information regarding their hierarchical relationships and these inferences are not affected by HGTs, which strongly support Darwin's views on evolution and classification. Expand
Primate phylogenomics uncovers multiple rapid radiations and ancient interspecific introgression

Molecular phylogenetics and the origins of placental mammals
TLDR
The potential weaknesses of limited character and taxon sampling are addressed in a comprehensive molecular phylogenetic analysis of 64 species sampled across all extant orders of placental mammals, providing new insight into the pattern of the early placental mammal radiation. Expand
Using genomic data to unravel the root of the placental mammal phylogeny.
TLDR
The genome sequence assemblies of human, armadillo, elephant, and opossum are analyzed to identify informative coding indels that would serve as rare genomic changes to infer early events in placental mammal phylogeny and suggest Afrotheria and Xenarthra diverged from other placental mammals approximately 103 (95-114) million years ago.

Primate molecular divergence dates.

An estimate of the molecular divergence dates for all of the major primate groups is presented, based on a Bayesian analysis of approximately 59.8 kbp of genomic data from 13 primates and 6 mammalian outgroups, using a range of paleontologically supported calibration estimates. Expand

TLDR
Phylogenetic analyses of the mitochondrial cytochrome oxidase subunit II gene give evidence that primates, tree shrews, and flying lemurs have a recent common ancestor but that bats are genealogically distant, and the monophyletic origin of bats is supported. Expand
Molecular and Morphological Supertrees for Eutherian (Placental) Mammals

The authors' combined and separate supertrees largely support the same suprafamilial taxa and orders, but different interordinal clades, which reinforce the continuing contributions of morphological studies, while highlighting the growing influence of molecular information on the field. Expand
Parallel adaptive radiations in two major clades of placental mammals
TLDR
Two independent molecular data sets, having aligned lengths of DNA of 5,708 and 2,947 base pairs, respectively, are analysed for all orders of placental mammals to resolve placental orders into four groups: Xenarthra, Afrotheria, Laurasiatheria, and Euarchonta plus Glires. Expand
Resolution of the Early Placental Mammal Radiation Using Bayesian Phylogenetics

Crown-group Eutheria may have their most recent common ancestry in the Southern Hemisphere (Gondwana), and placental phylogeny is investigated using Bayesian and maximum-likelihood methods and a 16.4-kilobase molecular data set. Expand

TLDR
A new statistical method is presented, based on an estimate of species preservation derived from a model of the diversification pattern, that suggests a Cretaceous last common ancestor of primates, approximately 81.5 Myr ago, close to the initial divergence time inferred from molecular data. Expand
