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.

Charles Darwin was a naturalist earned fame for the 'Theory of Evolution'. He was born on 12 February 1809 in Shrewsbury England. His father Robert Waring Darwin was a medical doctor and mother Susannah Wedgwood belonged to a famous pottery family. In his childhood he went Shrewsbury School, academically he was not good. For advanced learning, his father sends him to Edinburgh University in Scotland to become a doctor but he was not interested and he joined Christ's College Cambridge.

As a naturalist Darwin got an opportunity to go to second sea voyage of H.M.S. Beagle to survey the coast of South America. On his voyage he studied plants and animal's life. His interests in life science evolved and after working more than 20 years, in 1859 his world fame work 'On the Origin of Species' was published. He explained theory of evolution by natural selection. He said that life on earth evolved from a common ancestor. On earth there is struggle for survival between members who have favourable traits they survive and reproduce, it is known as survival of fittest. Well adapted species survived and less became extinct. Earlier Darwin faced criticism but later he earned honour for the theory. Darwin died on 19 April 1882.
