Natural selection states that given these three conditions, a population will accumulate the traits that enable more successful competition. “Origin of the species by means of natural selection” (Darwin, 1859) Darwin used several lines of evidence: 1. Artificial Selection was used as an analogy for natural selection: If humans can breedNatural Selection is a scientific theory because is is based on hypotheses drawn from many observations of the natural world; those hypotheses lead to tests that can be used to generate new knowledge, or refute the hypotheses should the tests fail.

he theory that organisms become adapted to their environment through the process of natural selection has become so ingrained in modern biological thought, and more generally in Western culture of the late 20th century, that it is surely one of the great scientific paradigms of the present era. Evolution 1 and adaptation were both well-accepted ...The process of natural selection has 4 main components: Variation, Inheritance, Rate of population growth and survival and reproduction. Variation within a population would make some individuals have a variety of different traits like the amount of body hair, offsprings, body size or markings. Individual variation are either helpful, harmful or ...Final answer. Which of the following are vital components of natural selection?
