The modern day horse Equus is a beloved icon but also, thanks to its many fossil relatives, has proved valuable for understanding macroevolution (that is, the long-term evolution of species). In his Perspective, MacFadden discusses fossil evidence supporting a branching family tree for the Family Equidae and points out why horse fossils have been beneficial for understanding evolution. 

Fossil Horses, Orthogenesis, and Communicating Evolution in Museums

It is indicated that more than half (55%) of natural history museums today still depict horse evolution as orthogenetic, despite the fact that paleontologists have known for a century that the actual evolutionary pattern of the Family Equidae is branching.

Genomics and the Evolutionary History of Equids.

An overview of genomic technologies have provided new analytical solutions that have enhanced understanding of equine evolution, including the species radiation within Equus; the extinction dynamics of several lineages; and the domestication history of two individual species.

The record of Cenozoic horses in Mexico: current knowledge and palaeobiological implications

The Mexican record shows that a considerable portion of the evolutionary history of horses occurred in Mexico, and including the Mexican specimens in studies using biogeographical, evolutionary and ecological approaches will considerably improve the knowledge of horses in southern North America.

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.

The Evolutionary Origin and Genetic Makeup of Domestic Horses

Recent advances in comparative genomics and paleogenomics that helped advance the understanding of the genetic foundation of domestic horses are reviewed.

Evolution of Old World Equus and origin of the zebra-ass clade

The cladistic analysis, based on cranial and postcranial elements, supports the monophyly of Equus, denies the recognition of PlesIPPus and Allohippus and supports the derivation of Equu grevyi and members of the zebra-ass clade from European stenonine horses.

Of mice and mammoths: evaluations of causal explanations for body size evolution in insular mammals

Aim  We investigated the hypothesis that the insular body size of mammals results from selective forces whose influence varies with characteristics of the focal islands and the focal species, and

Evolution of the Family Equidae, Subfamily Equinae, in North, Central and South America, Eurasia and Africa during the Plio-Pleistocene

Simple Summary The family Equidae enjoys an iconic evolutionary record, especially the genus Equus which is actively investigated by both paleontologists and molecular biologists. Nevertheless, a

Evolutionary history of the butterfly subfamily Satyrinae (Lepidoptera: Nymphalidae)

An overview of the evolutionary history of Satyrinae butterflies (Lepidoptera: Nymphalidae) is presented by using Bayesian and cladistic methods and a phylogenetic hypothesis is developed as a basis for this analysis.



A survey of equid mitochondrial DNA: Implications for the evolution, genetic diversity and conservation of Equus

The phylogenetic analysis of the mitochondrial DNA sequences of the control region and 12S rRNA gene provides further evidence that the deepest node in the phylogeny of the extant species is a divergence between twolineages, with the later speciation events of the zebras and asses occurring either as one or more rapid radiations, or withextensive secondary contact after speciation.

Walker's mammals of the world

From aardwolves and bandicoots to yapoks and zorillas, Ernest P. Walker's Mammals of the World is the most comprehensive-the pre-eminent-reference work on mammals. Now, completely revised and

Quo vadis eohippus? The systematics and taxonomy of the early Eocene equids (Perissodactyla)

This analysis supports the identification of Hyracotherium as a primitive equoid and its restriction to the genotype, HyrACotherium leporinum, and allies it with Cymbalophus near the base of the perissodactyl radiation.

It is suggested that the early Miocene browser-rich communities may reflect higher levels of primary productivity in Miocene vegetation, compared with equivalent present-day vegetation types.

Cope's Rule

Cope's Rule—that famous 19th-century notion that there is a general tendency toward size increase in evolution (J. Alroy, Reports, 1 May, p. [731][1])–has become a fixture of debates about pattern

Global vegetation change through the Miocene/Pliocene boundary

Between 8 and 6 million years ago, there was a global increase in the biomass of plants using C4 photosynthesis as indicated by changes in the carbon isotope ratios of fossil tooth enamel in Asia,
