WebJun 4, 2024 · Natural selection is one of the mechanisms that drives evolution. To be an active characteristic or trait causing natural selection to take place, the trait has to have the following features: Heritability. A trait can only influence evolution through natural selection if it is passed on from parents to descendants. Functionality. WebNatural selection. Individuals produce more offspring than their environment can support, and some die because of factors such as predation, food shortage or disease. These factors are known as ...

Without a working knowledge of natural selection, it is impossible to understand how or why living things have come to exhibit their diversity and complexity.
WebMar 5, 2024 · How does the theorem help us understand evolution in the real world? From the theorem, we can infer factors that cause allele frequencies to change. These factors are the "forces of evolution." There are four such forces: mutation, gene flow, genetic drift, and natural selection. Natural selection will be discussed in the "Natural Selection ... WebSo natural selection causes variation and adaptations and these variations and adaptations are caused because of genetic changes/mutations, meiosis, sexual reproduction for certain types of adaptations, but environmental circumstances is what causes behavioral adaptations to happen? because a change in the environment causes populations of the …

WebThe Hardy-Weinberg equilibrium principle says that allele frequencies in a population will remain constant in the absence of the four factors that could change them. Those factors are natural selection, mutation, genetic drift, and migration (gene flow). In fact, we know they are probably always affecting populations.
