THE DIFFERENT FORMS OF FLOWERS ON PLANTS OF THE SAME SPECIES (eBook, ePUB)

Beschreibung

"The Different Forms of Flowers on Plants of the Same Species" is a seminal paintings authored by Charles Darwin, the famend British naturalist and evolutionary biologist. This book represents a tremendous contribution to the observe of sexual replica in plant life. In this work, Darwin meticulously examines the charming phenomenon of heterostyly, which involves the presence of wonderful floral forms within a single plant species. He offers a complete account of his experiments and observations on diverse plant species, including primroses and cowslips, to recognize the motive and significance of those extraordinary floral bureaucracy. Darwin's crucial hypothesis is that heterostyly serves as a mechanism to sell move-pollination, thereby increasing the genetic variety of plant populations. He explores how the particular preparations of stigma and anthers in special floral bureaucracy encourage pollinators to switch pollen among vegetation of various bureaucracy, preventing self-fertilization. Darwin's work on floral heteromorphism now not best contributes to our information of plant reproductive strategies but additionally extends his concept of natural choice to the area of botany. He emphasizes the position of variation and selection within the evolution of floral forms and the ecological relationships between vegetation and their pollinators.

Autor

Charles Robert Darwin, (12 February 1809 - 19 April 1882) was an English naturalist, geologist and biologist, best known for his contributions to the science of evolution. His proposition that all species of life have descended over time from common ancestors is now widely accepted, and considered a foundational concept in science. In a joint publication with Alfred Russel Wallace, he introduced his scientific theory that this branching pattern of evolution resulted from a process that he called natural selection, in which the struggle for existence has a similar effect to the artificial selection involved in selective breeding. Darwin's early interest in nature led him to neglect his medical education at the University of Edinburgh; instead, he helped to investigate marine invertebrates. Studies at the University of Cambridge (Christ's College) encouraged his passion for natural science. His five-year voyage on HMS Beagle established him as an eminent geologist whose observations and theories supported Charles Lyell's conception of gradual geological change, and publication of his journal of the voyage made him famous as a popular author. Puzzled by the geographical distribution of wildlife and fossils he collected on the voyage, Darwin began detailed investigations, and in 1838 conceived his theory of natural selection. Although he discussed his ideas with several naturalists, he needed time for extensive research and his geological work had priority. He was writing up his theory in 1858 when Alfred Russel Wallace sent him an essay that described the same idea, prompting immediate joint publication of both of their theories. Darwin's work established evolutionary descent with modification as the dominant scientific explanation of diversification in nature. Darwin has been described as one of the most influential figures in human history, and he was honoured by burial in Westminster Abbey.
