Sexual selection

Species, explains his theory of natural selection and its power to shape the evolution of species with help from the example of how species are shaped through domestication, or rather, artificial selection. With the example of domestication, however, there is a potential obstacle as to the validity his theory. Fleeming Jenkin presents this obstacle by saying Darwin’s theory “rests on the assumption that natural selection can do slowly what man’s selection does quickly” (Jenkin, pg. 3). And…

The effect technology may have on future human evolution can be determined via analysis of various developmental and technological factors. Uncovering the possibilities of potential further evolution requires a familiarisation with Darwinian development and the purpose for its occurrence. A reflection of current and past technologies and their subsequent repercussions on society also assist in defining the specific impacts on future humans. In order predict the essence of mankind in coming…

On November 24th, 1859 he published his best known work, On the Origins of Species by Means of Natural Selection. He died on April 19th, 1882. Throughout the century as we research DNA we have revealed more evidence pointing towards Darwin’s Theory being correct. Over one hundred years later his findings are still controversial due to its conflict with Creationism…

managed to develop a set of laws explaining the evolution of species, which later became the backbone of biology. Impressive. You have made one of the most important contributions to the science of evolution; your concept of natural selection. Natural selection is the basis for our understanding of how species evolve over time. The idea that the members of a species compete with each other in a fight to see who can be better adapted to their environment and gain a larger advantage of…

The acquisition of resources in animals is an important influence on the structure and actions of a species since individuals want to pass their genes onward to survive. However, interspecific competition affects the availability of these resources and therefore influences the methods by which a species obtains them. Surf Scoter ducks demonstrate a synchronous dive and surfacing pattern, as investigated by LE Schenkeveld and RC Ydenberg, as a tactic to overpower kleptoparasites – animals who rob…
