Did you know?
WebNatural selection is an important mechanism of evolution. But is it the only mechanism? Nope! In fact, sometimes evolution just happens by chance. In population genetics, evolution is defined as a change in the frequency of alleles (versions of a gene) in a population over time. WebBy definition, natural selection is a function of populations. It is a process involving populations over the course of time, not determined by only one individual. We are …
Natural selection is the differential survival and reproduction of individuals due to differences in phenotype. It is a key mechanism of evolution, the change in the heritable traits characteristic of a population over generations. Charles Darwin popularised the term "natural selection", contrasting it with artificial selection, which is intentional, whereas natural selection is not.

WebJan 23, 2024 · Natural selection only acts on the population’s heritable traits: selecting for beneficial alleles and, thus, increasing their frequency in the population, while selecting against deleterious alleles and, thereby, decreasing their frequency. This process is known as adaptive evolution (Figure 4.1.3.1 ). fly on the windshieldWebNatural selection is a driving force in evolution and can generate populations that are better adapted to survive and successfully reproduce in their environments. However, natural selection cannot produce the perfect organism. Natural selection can only select on existing variation in the population.
