About this Research Topic
The Plio–Pleistocene evolutionary stage of horse evolution is punctuated by the great climatic fluctuations of the Quaternary beginning 2.6 Ma which influenced Equus evolution, biogeographic dispersion and adaptation on a nearly global scale. The evolutionary biology of Equus evolution across its entire range remains relatively poorly understood and often highly controversial. Some of this lack of understanding is due to assumptions that have arisen because of the relatively derived craniodental and postcranial anatomy of Equus and its close relatives which has seemed to imply that that these forms occupied relatively homogenous and narrow dietary and locomotor niches - notions that have not been adequately addressed and rigorously tested. Other challenges have revolved around teasing apart environmentally-driven adaptation versus phylogenetically defined morphological change. Geochronologic age control of localities, geographic provinces and continents has improved, but in no way is absolute and can be reexamined in our proposed volume. Temporal resolution for paleodietary, paleohabitat and paleoecological interpretations are also challenging for understanding the evolution of Equus. Our proposed volume attempts to assemble a group of experts who will address multiple dimensions of Equus’ evolution in time and space.
Within the framework of this Research Topic, we propose to request and will integrate contributions from the following suite of topics that will contribute to our understanding of the evolution of Equus across all the continents it has occupied. We propose that the topics include: origin of Equus, taxonomy, paleoclimate, evolution, paleoecology, diversity, ecomorphology, biogeography, genetics and molecular biology and geochronologic framework. The ultimate goal for this Research Topic is to present a comprehensive global overview of Equus evolutionary biology and paleoecology.
