Abstract The supraordinal mammalian clade Afrotheria was first recognized in its entirety based on DNA analysis dating to the mid-1990s. Since then, this “African clade”, which includes proboscideans, sirenians, hyracoids, tubulidentates, elephant-shrews, tenrecs and chrysochlorids, has been supported by numerous molecular and genomic studies. According to these molecular inferences, the origin of crown Afrotheria goes back into the Cretaceous, with estimates from over 100 to under 80 Mya… Expand

Out of Africa: A New Afrotheria Lineage Rises From Extinct South American Mammals
The South American native ungulates (SANUs) are usually overlooked in Eutherian phylogenetic studies. In the rare studies where they were included, the diversity of SANUs was underrated, keepingExpand
The Oldest and Youngest Records of Afrosoricid Placentals from the Fayum Depression of Northern Egypt
Tenrecs (Tenrecoidea) and golden moles (Chrysochloroidea) are among the most enigmatic mammals alive today. Molecular data strongly support their inclusion in the morphologically diverse cladeExpand
Recapitulating the evolution of Afrotheria: 57 genes and rare genomic changes (RGCs) consolidate their history
TLDR
The interordinal afrotherians phylogeny presented here contributed to the elucidation of the evolutionary history of this ancient clade of mammals, which is one of the most unorthodox proposals in mammalian biology. Expand
Cranial Remain from Tunisia Provides New Clues for the Origin and Evolution of Sirenia (Mammalia, Afrotheria) in Africa
TLDR
X-ray microtomography is used to investigate a newly discovered sirenian petrosal from the Eocene of Tunisia, which represents the oldest occurrence of sirenians in Africa and supports their African origin. Expand
Interordinal gene capture, the phylogenetic position of Steller's sea cow based on molecular and morphological data, and the macroevolutionary history of Sirenia.
TLDR
A synthetic evolutionary tree for living and fossil sirenians showing several key innovations in the history of this clade including character state changes that parallel those that occurred in the evolutionary history of cetaceans is presented. Expand
A Phororhacoid bird from the Eocene of Africa
TLDR
Two hypotheses are proposed to account for the presence of a phororhacoid bird in Africa, either an early dispersal of small members of this group, which were still able of a limited flight, or a transoceanic migration of flightless birds from South America to Africa during the Paleocene or earliest Eocene. Expand
The enigmatic evolutionary relationships of Palaeocene mammals and their relevance for the Tertiary radiation of placental mammals
TLDR
By building the largest cladistic data matrix to date, this thesis test the relationships of mammals from the earliest Cenozoic, and from the resulting phylogenies, test the hypotheses that the end-Cretaceous mass extinction resulted in an adaptive radiation of placental mammals. Expand
Phylogeny and systematics of the Orycteropodidae (Mammalia, Tubulidentata)
TLDR
The present revision of the Orycteropodidae deals with the phylogeny and systematics of all African and Eurasian species over the last 20 Myr and proposes a consistent palaeobiogeographical scenario for aardvarks. Expand
The new framework for understanding placental mammal evolution
TLDR
Compared with previous hypotheses this tree is remarkably stable; however, some uncertainty persists about the location of the placental root, and (for example) the position of bats within laurasiatheres, of sea cows and aardvarks within afrotheres, and of dermopterans within euarchontoglires. Expand
Strong morphological support for the molecular evolutionary tree of placental mammals
TLDR
Morphology remains relevant in the genomic age, providing vital independent corroboration of the molecular tree of mammals, using an extensive morphological and molecular dataset totalling 17 431 characters. Expand

Early Tertiary mammals from North Africa reinforce the molecular Afrotheria clade
TLDR
New dental and postcranial evidence of Eocene stem hyrax and macroscelidid from North Africa are reported that, for the first time, provides a congruent phylogenetic view with the molecular Afrotheria clade. Expand
Phylogenomic data analyses provide evidence that Xenarthra and Afrotheria are sister groups.
TLDR
The phylogenetic analysis joined Xenarthra and Afrotheria on a common branch, Atlantogenata, and this topology was found to fit the data significantly better than the alternative trees, and exceeds by a considerable margin that of any previous study. Expand
Relationships of Endemic African Mammals and Their Fossil Relatives Based on Morphological and Molecular Evidence
TLDR
Analyses of anatomical and DNA sequence data run on a parallel supercomputer that include fossil taxa support the inclusion of tenrecs and golden moles in the Afrotheria, an endemic African clade of placental mammals, and support the position of AfroTheria as well-nested, not basal, within Placentalia.

A new estimate of afrotherian phylogeny based on simultaneous analysis of genomic, morphological, and fossil evidence

TLDR
There may, nevertheless, be more morphological character support for crown Afrotheria than is currently assumed; the features identified here as possible afrotherian synapomorphies can be further scrutinized through future phylogenetic analyses with broader taxon sampling, as well as recovery of primitive fossil afroTherians from the Afro-Arabian landmass. Expand
Genome Size: A Novel Genomic Signature in Support of Afrotheria
TLDR
It is shown that the GSs of six selected representatives across the Afrotheria supraordinal group are among the highest for the extant Placentalia, providing a novel genomic signature of this enigmatic group that should assist in planning new genome sequencing initiatives. Expand
A retroposon analysis of Afrotherian phylogeny.
TLDR
It is concluded that these three lineages diverged very rapidly in a very short evolutionary period, with the consequence that ancestral polymorphism present in the last common ancestor of Paenungulata results in such incongruence. Expand
Afrotherian origins and interrelationships: new views and future prospects.
TLDR
The chapter concludes that the possible inability of sequence data to conclusively resolve many of the evolutionary relationships within afrotheria and propose that an emphasis on the identification of so-called rare genomic changes (RGCs) may ultimately provide the most convincing resolution of afroTherian supraordinal phylogeny. Expand
Ancient SINEs from African endemic mammals.
TLDR
A novel family of SINEs, designated AfroSines, was isolated and characterized from the genomes of afrotherians, suggesting monophyly of these three groups, which was previously proposed as Paenungulata. Expand
Affinities of ‘hyopsodontids’ to elephant shrews and a Holarctic origin of Afrotheria
TLDR
As the oldest record of an afrothere clade, identification of macroscelidean relatives in the North American Palaeocene argues against an African origin for Afrotheria, weakening support for linking placental diversification to the break-up of Gondwana. Expand
A new genus of Macroscelidea (Mammalia) from the Eocene of Algeria: a possible origin for elephant-shrews
TLDR
The phylogenetic analysis suggests also that the Macroscelidea-Microhyus clade is closely related to the Proboscidea, and provides evidence for a macroscelid-tethytherian relationship. Expand
