Origin of Species

The origin of species has fascinated both biologists and the general public since the publication of Darwin's "Origin of Species" in 1859. Significant progress in understanding the process was achieved in the "modern synthesis," when Theodosius Dobzhansky, Ernst Mayr, and others reconciled Mendelian genetics with Darwin's natural selection. Although evolutionary biologists have developed significant new theory and data about speciation in the years since the modern synthesis, this book represents the first systematic attempt to summarize and generalize what mathematical models tell us about the dynamics of speciation. "Fitness Landscapes and the Origin of Species presents both an overview of the forty years of previous theoretical research and the author's new results. Sergey Gavrilets uses a unified framework based on the notion of fitness landscapes introduced by Sewall Wright in 1932, generalizing this notion to explore the consequences of the huge dimensionality of fitness landscapes that correspond to biological systems. In contrast to previous theoretical work, which was based largely on numerical simulations, Gavrilets develops simple mathematical models that allow for analytical investigation and clear interpretation in biological terms. Covering controversial topics, including sympatric speciation and the effects of sexual conflict on speciation, this book builds for the first time a general, quantitative theory for the origin of species.

In the Origin of Species (1859) Darwin challenged many of the most deeply held beliefs of the Western world. Arguing for a material, not divine, origin of species, he showed that new species are achieved by 'natural selection'. Development, diversification, decay, extinction and absence of plan are all inherent to his theories. Darwin read prodigiously across many fields; he reflected on his experiences as a traveller, he experimented. His profoundly influential concept of 'natural selection' condenses materials from past and present, from the Galapagos Islands to rural Staffordshire, from English back gardens to colonial encounters. The Origin communicates the enthusiasm of original thinking in an open, descriptive style, and Darwin's emphasis on the value of diversity speaks more strongly now than ever.

The Origin of Species - First published on November 24, 1859, The Origin of Species (full title On the Origin of Species by Means of Natural Selection, or the Preservation of Favoured Races in the Struggle for Life) by British naturalist Charles Darwin is one of the pivotal works in scientific history, and arguably the pre-eminent work in biology. In it, Darwin makes "one long argument" for his theory that "groups" of organisms, (which we now call populations) rather than individual organisms, gradually evolve through ...

Genetics and the Origin of Species - Genetics and the Origin of Species (ISBN 0231054750) is a 1937 book by the Ukrainian-American evolutionary biologist Theodosius Dobzhansky and one of the important books of the modern evolutionary synthesis. A third edition was published in 1951.

On the Tendency of Species to form Varieties; and on the Perpetuation of Varieties and Species by Natural Means of Selection - Two scientific papers; On the Tendency of Species to form Varieties by Alfred Russel Wallace and on the Perpetuation of Varieties and Species by Natural Means of Selection by Charles Darwin were presented to the Linnean Society of London in 1858 that first publicised Darwin — Wallace theory of evolution by natural selection. Darwin's On the Origin of Species would follow a year later.

Hybrid-origin - The Hybrid-origin hypothesis of human origins argues that all of the genetic variation between the contemporary human races is attributable to genetic inheritance from two widely divergent hominid species, or subspecies, that were geographically dispersed throughout Africa, Southeast Asia and the Indian subcontinent, prior to the evolution of modern Homo sapiens sapiens (according to hybrid-origin theory, approximately 35,000 years ago).
