Description: Contributions to the Theory of Natural Selection a Series of Essays by Russel Wallace Alfred, Alfred Russel Wallace Estimated delivery 3-12 business days Format Paperback Condition Brand New Description Alfred Russel Wallaces key work "Contributions to the Theory of Natural Selection" is a foundational work. Wallace, a prominent naturalist and Charles Darwins colleague, made vital contributions to the development of natural selection theory, and this collection of writings is a testimony to his trailblazing views. Wallace provides his views into the mechanisms of evolution and natural selection in a series of articles and papers in the book. He explores several elements of evolutionary biology in these essays, such as the concept of adaptive coloration in animals, species distribution, and the function of sexual selection in evolution. The notion of "Wallaces Line," which delineates the boundary between distinct zoogeographical zones in Southeast Asia, is one of Wallaces most important achievements. This concept has aided our knowledge of how species are dispersed over the world. Wallaces work also includes his opinions on human evolution and the probable impact of natural selection on human mental and moral qualities. In this sense, his theories provoked significant discussions and controversies within the scientific world. "Contributions to the Theory of Natural Selection" showcases Alfred Russel Wallaces extraordinary intelligence as well as his pivotal role in developing the discipline of evolutionary biology. Author Biography Alfred Russel Wallace OM FRS was an English naturalist, explorer, geographer, anthropologist, biologist, and illustrator who lived from 8 January 1823 to 7 November 1913. He independently developed the theory of evolution by natural selection, and his work on the subject was published in 1858, with excerpts from Charles Darwins earlier papers on the subject. It inspired Darwin to abandon the "big species book" he was working on and rapidly compose an abstract, which was published in 1859 as On the Origin of Species. Wallace conducted significant field research, beginning in the Amazon River basin. He then conducted fieldwork in the Malay Archipelago, where he discovered the Wallace Line, which divides the Indonesian archipelago into two distinct parts: a western portion with animals primarily of Asian origin, and an eastern portion with animals primarily of Australasia. He was regarded as the preeminent authority on the geographical distribution of animal species in the nineteenth century, and is frequently referred to as the "father of biogeography," or more particularly zoogeography. Wallace was a notable evolutionary thinker of the nineteenth century, working on warning coloration in animals and reinforcement (also referred to as the Wallace effect), a method by which natural selection could contribute to speciation by stimulating the establishment of barriers against hybridization.
