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 ...

Evolutionary biologists use the word fitness to describe how good a particular genotype is at leaving offspring in the next generation relative to other genotypes. So if brown beetles consistently leave more offspring than green beetles because of their color, you'd say that the brown beetles had a higher fitness. In evolution, fitness is about success atStudy with Quizlet and memorize flashcards containing terms like who was the first to believe that populations could change over time?, what was Lamarck's Theory of Evolution?, what was Darwin's Theory of Evolution? and more.Natural selection, Darwin argued, was an inevitable outcome of three principles that operated in nature. First, most characteristics of organisms are inherited, or passed from parent to offspring.

More than 150 years ago, naturalist Charles Darwin discovered that life on Earth continues to evolve by the process of natural selection.John Turner/Getty Images The first of these factors that must be present in order for Natural Selection to occur is the ability of a population to overproduce offspring. You may have heard the phrase "reproduce like rabbits" which means to have a lot of offspring quickly, much like it seems rabbits do when they mate.What are the 4 key components of the theory of natural selection proposed by Charles Darwin?
