What is theory of charles darwin |
| Answer» \t\tCharles Darwin was a British naturalist who proposed the theory of biological evolution by natural selection.\t\t\tDarwin defined\xa0evolution\xa0as "descent with modification," the idea that species change over time, give rise to new species, and share a common ancestor.\t\t\tThe mechanism that Darwin proposed for evolution is\xa0natural 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.\t\t\tNatural selection causes populations to become\xa0adapted, or increasingly well-suited, to their environments over time. Natural selection depends on the environment and requires existing heritable variation in a group.\t | |
