Show More. 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 ... Natural selection involves two components of fitness: reproduction and survival. Under sexual selection, traits that increase reproduction are selected for. In many cases, these traits can reduce survival of the individual, but the overall fitness of the organism is still high due to the enhanced fitness from reproduction.How was the theory of evolution developed? - OCR 21st CenturyDarwin and natural selection.

Charles Darwin and Alfred Wallace are the two co-discoverers of natural selection (Darwin & Wallace 1858), though, between the two, Darwin is the principal theorist of the notion whose most famous work on the topic is On the Origin of Species (Darwin 1859). For Darwin, natural …The Four Factors of Natural Selection. Natural selection is one of the four basic premises of evolutionary theory, alongside mutation, migration and genetic drift. Natural selection works on populations with a variation in traits, such as coloring. Its main premise is that when there is a trait that allows one individual to better survive in an ...Nature selects the variations that are most useful. Therefore, he called this type of selection natural selection. Darwin knew artificial selection could change domestic species over time. 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.
