write short notes on darwin theory of natural selection
Answers
Answer:
The mechanism that Darwin proposed for evolution is natural selection. Because resources are limited in nature, organisms with heritable traits that favor survival and reproduction will tend to leave more offspring than their peers, causing the traits to increase in frequency over generations.
Darwin's Theory of Evolution by Natural Selection
More individuals are produced each generation that can survive. Phenotypic variation exists among individuals and the variation is heritable. Those individuals with heritable traits better suited to the environment will survive.Darwinism is a theory of biological evolution developed by the English naturalist Charles Darwin (1809–1882) and others, stating that all species of organisms arise and develop through the natural selection of small, inherited variations that increase the individual's ability to compete, survive, and reproduce.
Answer:
After a long period of time, the species may be very different from the original individuals of the same species. But if this changed species shows successful adaptation and growth in the given environment then it gets evolved. This process of development of the species is called natural selection.
