One component of natural selection is the fitness level of each individual in a population. If an individual has low fitness, then natural selection will act on that individual, killing it, and making it so it doesn’t produce any offspring. Another component are selective pressures, because these pressures play a role in the ...Darwinism, theory of the evolutionary mechanism propounded by Charles Darwin as an explanation of organic change.

Variation - Organisms must be different and carry different genes. Competition - Organisms compete for resources.Final answer. Which of the following are vital components of natural selection? (Select all that apply, points deducted for incorrect responses.) A population typically produces a large number of offspring, only some of whom survive to adulthood. All members of the species share the same genes (or alleles) that can be passed on to offspring ...Key points: Charles Darwin was a British naturalist who proposed the theory of biological evolution by natural selection. Darwin defined evolution as "descent with modification," the idea that species change over time, give rise to new species, and share a common ancestor. The mechanism that Darwin proposed for evolution is natural selection.

He inferred that natural selection could also change species over time. In fact, he thought that if a species changed enough, it might evolve into a new species.The Theory of Natural Selection explains the diversity of life on Earth using a few key principles: Species, faced with a selection pressure from their environment, can either adapt or be threatened, possibly with extinction if they are completely unable to adapt.
