Download or read book Fossils Phylogeny and Form written by Jonathan M. Adrain and published by Springer Science & Business Media. This book was released on 2002-01-31 with total page 420 pages. Available in PDF, EPUB and Kindle. Book excerpt: Phylogenetic analysis and morphometrics have been developed by biologists into rigorous analytic tools for testing hypotheses about the relationships between groups of species. This book applies these tools to paleontological data. The fossil record is our one true chronicle of the history of life, preserving a set of macroevolutionary patterns; thus various hypotheses about evolutionary processes can be tested in the fossil record using phylogentic analysis and morphometrics. The first book of its type, Fossils, Phylogeny, and Form will be useful in evolutionary biology, paleontology, systematics, evolutionary development, theoretical biology, biogeography, and zoology. It will also provide a practical, researcher-friendly gateway into computer-based phylogenetics and morphometrics.

Book excerpt: "One. A large collection, mainly of isolated molars, from Águas do Araxá, Brazil, seems to represent a single population within a species identified as Haplomastodon waringi. The variation, described in some detail, is far greater than has hitherto usually been taken into consideration in the diagnosis of supposed species of mastodonts. 2. Mastodonts have been found at many localities scattered throughout Brazil. A few specimens are anomalous, but the great majority belong to, or are at least inseparable from, H. waringi on the basis of known characters. 3. Ecuadorian Haplomastodon is not at present specifically separable from H. waringi, and neither in Brazil nor in Ecuador is there good evidence of the presence of more than one species (or subgenus). 4. The only species and genera that now seem to be clearly distinct among South American mastodonts are Cuvieronius hyodon, Haplomastodon waringi, and Stegomastodon platensis. All these names have numerous synonyms. The species Stegomastodon superbus and the genus and species Notiomastodon ornatus are also tentatively listed as distinct, but are of doubtful status. 5. Haplomastodon is believed to be about as closely related to Cuvieronius as to Stegomastodon. 6. All the South American mastodonts seem to represent end terms of divergence within a single broad stock. Cuvieronius, Stegomastodon, and probably also Haplomastodon were already differentiated before they spread from North America to South America. The North American Rhynchotherium may belong to the same complex. All may ultimately have arisen from early Old World Anancinae, and all are tentatively referred to that subfamily"--P. 185.

Available in PDF, EPUB and Kindle. Book excerpt: One of the most important questions we can ask about life is -Does ecology matter?- Most biologists and paleontologists are trained to answer -yes, - but the exact mechanisms by which ecology matters in the context of patterns that play out over millions of years have never been entirely clear. This book examines these mechanisms and looks at how ancient environments affected evolution, focusing on long-term macroevolutionary changes as seen in the fossil record. Evolutionary paleoecology is not a new discipline. Beginning with Darwin, researchers have attempted to understand how the environment has affected evolutionary history. But as we learn more about these patterns, the search for a new synthetic view of the evolutionary process that integrates species evolution, ecology, and mass extinctions becomes ever more pressing. The present volume is a benchmark sampler of active research in this ever more active field.
