Genomics and the Evolutionary History of Equids.

The equid family contains only one single extant genus, Equus, including seven living species grouped into horses on the one hand and zebras and asses on the other. In contrast, the equine fossil record shows that an extraordinarily richer diversity existed in the past and provides multiple examples of a highly dynamic evolution punctuated by several waves of explosive radiations and extinctions, cross-continental migrations, and local adaptations. In recent years, genomic technologies have… 
Radiocarbon and genomic evidence for the survival of Equus Sussemionus until the late Holocene
This work presents the first high-quality complete genome of the Sussemionus lineage, which was sequenced to 13.4× depth of coverage and found that the small genetic diversity, rather than enhanced inbreeding, limited the species’ chances of survival.
Ancient genomes redate the extinction of Sussemionus, a subgenus of Equus, to late Holocene
The first high-quality complete genome of the Sussemionus is presented and it is demonstrated that it survived until ∼3,500 years ago, despite the continued demographic collapse during the Last Glacial Maximum and the great human expansion in East Asia.
Ancient horse genomes reveal the timing and extent of dispersals across the Bering Land Bridge
The results suggest that barriers to gene flow played an important role in shaping the early genetic history of caballine horses, including the ancestors of living horses within Equus ferus.
The Piroplasmida Babesia, Cytauxzoon, and Theileria in farm and companion animals: species compilation, molecular phylogeny, and evolutionary insights.
A compilation of all piroplasmid species, isolates, and species complexes that infect domestic mammals and which have been well defined by molecular phylogenetic markers is presented, showing diversification of parasite species appears to be dominated by host-parasite cospeciation (Fahrenholz's rule).

Comparative Analysis of Microbiome Metagenomics in Reintroduced Wild Horses and Resident Asiatic Wild Asses in the Gobi Desert Steppe
The results indicate that sympatric wild equids differ in their microbial composition while harboring a stable microbial functional core, which may enable them to survive in challenging habitats.
Seeking Horses: Allies, Clients and Exchanges in the Zhou Period (1045–221 BC)
Horses and chariots—and the associated technology and expertise—derived from the steppe contributed to the success of the Zhou conquest of the Shang in c. 1045 BC and remained important throughout

Revising the recent evolutionary history of equids using ancient DNA
Phylogenetic analyses support a major revision of the recent evolutionary history of equids and reveal two new species, a South American hippidion and a descendant of a basal lineage potentially related to Middle Pleistocene equids.
A new genus of horse from Pleistocene North America
The palaeogenomic and morphometric analyses support the idea that there was only a single species of middle to late Pleistocene NWSL equid, and a new genus, Haringtonhippus, is proposed for the sole species H. francisci.
Evolution, Systematics, and Phylogeography of Pleistocene Horses in the New World: A Molecular Perspective
It is shown that stilt-legged horses, commonly regarded as Old World migrants related to the hemionid asses of Asia, were in fact an endemic North American lineage, and the data suggest that there were fewer horse species in late Pleistocene North America than have been named on morphological grounds.
Speciation with gene flow in equids despite extensive chromosomal plasticity
These findings challenge the claim that the accumulation of chromosomal rearrangements drive complete reproductive isolation, and promote equids as a fundamental model for understanding the interplay between chromosomal structure, gene flow, and, ultimately, speciation.
Mitochondrial Phylogenomics of Modern and Ancient Equids
Bayesian and Maximum Likelihood phylogenetic inference confirms that zebras are monophyletic within the genus Equus, and the Plains and Grevy’sZebras form a well-supported monophyletsic group, and additional mitochondrial genome sequence data is required before revisiting the exact timing of the lineage radiation leading up to modern equids.
Molecular identification of late and terminal Pleistocene Equus ovodovi from northeastern China
Comparison of the three near-complete mitochondrial genomes retrieved from three equid fossil specimens excavated from northeastern China suggests a genetic diversity similar to several extant species of the genus Equus, including E. ovodovi.
Recalibrating Equus evolution using the genome sequence of an early Middle Pleistocene horse
Thealyses suggest that the Equus lineage giving rise to all contemporary horses, zebras and donkeys originated 4.0–4.5 million years before present, twice the conventionally accepted time to the most recent common ancestor of the genus Equus, and supports the contention that Przewalski's horses represent the last surviving wild horse population.
Taxonomic evolution in North American Neogene horses (subfamily Equinae): the rise and fall of an adaptive radiation
The history of the subfamily Equinae (exclusive of Archaeohippus and “ Parahippus ”) in North America consisted of a 3-m.y.y., radiation phase, steady-state diversity phase, and reduction phase, during which extinction rates increased fourfold during the reductionphase, while speciation rates declined slightly.
A rapid loss of stripes: the evolutionary history of the extinct quagga
It is shown that the quagga displayed little genetic diversity and very recently diverged from the plains zebra, probably during the penultimate glacial maximum, which emphasizes the importance of Pleistocene climate changes for phylogeographic patterns in African as well as Holarctic fauna.
