Whales are mammals that moved to the sea some 50 million years ago. The question of who their ancestors were has vexed scientists for years. In his Perspective, [Rose][1] highlights the report by [ Gingerich et al .][2], who report unusually well-preserved primitive whale fossils. Rose explains that these fossils reconcile morphological and molecular data for the first time, indicating that whales evolved from even-toed ungulates (hoofed animals) rather than mesonychians (an extinct group of… 
On the origin of Cetartiodactyla: Comparison of data on evolutionary morphology and Molecular biology
Molecular similarity between Hippopotamidae and Cetacea is evidence of common origin of Artiodactyla andCetacea and adaptation to aquatic environment.
Calibration and error in placental molecular clocks: a conservative approach using the cetartiodactyl fossil record.
Reestimates of the minimum and maximum fossil age estimates of the divergence of whales from artiodactyls, a commonly used anchor point for calibrating both mitogenomic and nucleogenomic placental timescales, indicate that disregard for fossil calibration error may inflate the power of the molecular clock when testing the time of ordinal diversification in context with the K-T boundary.
The position of Hippopotamidae within Cetartiodactyla.
This morphological analysis of a comprehensive set of taxa and characters offers a robust solution to the origins of Hippopotamidae, which appears to be deeply nested within the otherwise extinct artiodactyl family Anthracotheriidae, most precisely within the most advanced selenodont forms.
Ecological evolution of early Cetartiodactyla and reconstruction of its missing initial link
The analysis of biodiversity and ecological evolution of Eocene Cetartiodactyla against the background of changes in the biosphere, biota, and paleogeography has provided a model for the origin,
Retinal Topography in Two Species of Baleen Whale (Cetacea: Mysticeti)
Eye morphology and the topographic distribution of retinal ganglion cells (RGCs) in two species of mysticete, Bryde’s whale and the humpback whale, are investigated, indicating that cetacean eyes are adapted to vision in dim light and adhere to a common “bauplan” that evolved prior to the divergence of the two cetACEan parvorders over 30 million years ago.
Macrobiomineralogy: Insights and Enigmas in Giant Whale Bones and Perspectives for Bioinspired Materials Science.
It is proposed that whale bone construction poses extreme requirements for inorganic material storage, mediated by biomacromolecules, and the concepts presented in this article highlight the beneficial uses of multidisciplinary and multiscale approaches to study the structural peculiarities of both organic and inorganic phases.
Whale Evolution: A Whale of a Tale
Areview of the evolution of whales from terrestrial land animals finds that the evidence used to support the current theory is either wrong or very questionable. A focus is on the hip bone and fetal


The position of Cetacea within mammalia: phylogenetic analysis of morphological data from extinct and extant taxa.
Knowledge of the phylogenetic position of the order Cetacea (whales, dolphins, and porpoises) within Mammalia is of central importance to evolutionary biologists studying the transformations of
Ankle morphology of the earliest Cetaceans and its implications for the phylogenetic relations among ungulates.
Tarsal data do not support Cete (Mesonychia plus Cetacea) and are consistent with the exclusion of perissodactyls from paenungulates as suggested by some molecular studies.
Comparative osteology of North American dichobunid artiodactyls.
The postcranial skeletal anatomy of the early Eocene dichobunid Diacodexis, the oldest known artiodactyl, is described, together with new material of Bunophorus, Antiacodon, Pentacemylus, and an undetermined homacodontine, indicating that they were uniformly highly adapted for cursorial-saltatorial locomotion.
Postcranial Osteology of the most Primitive Artiodactyl: Diacodexis pakistanensis (Dichobunidae)
Diacodexis pakistanensis is the smallest and most primitive artiodactyl and has five complete digits in the manus and four in the pes and is digitigrade.
Classification of mammals : above the species level
Malcolm C. McKenna and Susan K. McKenna inherited the project from Simpson and, with Bell, has constructed a completely updated hierarchical system that reflects the genealogy of Mammalia.
Origin of Whales from Early Artiodactyls: Hands and Feet of Eocene Protocetidae from Pakistan
Partial skeletons of two new fossil whales, Artiocetus clavis and Rodhocetus balochistanensis, are among the oldest known protocetid archaeocetes, and are important in augmenting the diversity of early Protocetidae and clarifying that Cetacea evolved from early Artiodactyla rather than Mesonychia.
Skeletons of terrestrial cetaceans and the relationship of whales to artiodactyls
Cladistic analysis of the skeletons of two early Eocene pakicetid cetaceans, the fox-sized Ichthyolestes pinfoldi, and the wolf-sized Pakicetus attocki, indicates that cetACEans are more closely related to artiodactyls than to any mesonychian, and supports monophyly of artiodACTyls.
