On The Evolution Of The Proboscidea

Excerpt from On the Evolution of the Proboscidea The accuracy of the hypothesis of an Ethiopian centre of' distribution of the Probosehlea has been fully demonstrated during the last two years by the discovery of a number of primitive members of the suh-order in the Middle and Upper Eocene beds of the F ayum district of Egypt, Where they occur associated With remains of other mammals, especially of early Hyracoidea, as well as of some remarkable reptiles. The great interest of this discovery Will be recognised When it is considered that in the paper by Professor osborn, above referred to, Africa is spoken of as the dark continent of palaeontology, for it has practically no fossil mammal history. The material for at least the beginning of such a history is now available, and it is to be hoped and expected that within the next few years much will be added to it.

This book details the long, diverse, and complex phylogenetic history of elephants and their fossil relatives (the Proboscidea), whose origin is deeply embedded some 60 million years ago in Africa. Most of the major evolutionary events of proboscideans occurred in Africa, and these are examined in their geological, paleoecological, geographic, and faunal contexts. Updated information about feeding adaptations, taxonomy and systematics, genetics, and site occurrences is included and summarized in tables, figures, and charts. This is the first comprehensive review of African proboscideans and illustrates the need to more actively protect elephants and ensure their survival in modern ecosystems. Key Features: Provides a comprehensive systematic review of the African proboscidean fossil record Includes a summary of taxonomy, geochronology, biogeography and morphology Documents major faunal events including those associated with hominin origins Synthesizes new data from genomic, isotopic, and microware analyses Emphasizes the role of elephants in ecosystems and the importance of conservation

The Proboscidea, of which only two species of elephant survive today, were one of the great mammalian orders of the Cenozoic. Their success over evolutionary time is reflected by their morphological and taxonomic diversity, their nearly worldwide distribution on every continent exceptAustralia and Antarctica, and their persistence through nearly fifty million years. Their great past ability to migrate and to adapt to changing climatic conditions and interspecific competition provides a unique laboratory for the testing of evolutionary theories and development of new concepts.This is the first complete treatise on the evolution and palaeoecology of this group for half a century. It reviews their classification and phylogeny, the early differentiation of proboscideans, the major adaptive radiations and their evolutionary patterns, and the origins and current status ofextant elephant species. Written by leading international experts, this is a major study documenting the record of terrestrial biodiversity.
