WebApr 9, 2009 · Natural selection is one of the central mechanisms of evolutionary change and is the process responsible for the evolution of adaptive features. 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. WebNatural 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. It does not create anything from scratch.

Algae → insects → salmon → bears The producers in the ecosystem produce 8,000,000 kilocalories of energy via photosynthesis. The bears need 100 kilocalories to survive. Can the ecosystem support the bears, and if WebUnlike natural selection, genetic drift does not depend on an allele’s beneficial or harmful effects. Instead, drift changes allele frequencies purely by chance, as random subsets of individuals (and the gametes of those individuals) are …

With the decline of religion, and the rise of science, for many in the modern world nihilism has taken hold. But this is a mistake. We must usher in the return of meaning, for the existential health of our selves and our culture, writes John Vervaeke.
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 ...
