Witryna4 cze 2024 · The three observations that allowed Darwin to develop his theory of evolution and natural selection were: The individuals in a population display a variation in traits such as color, behavior, size and shape due to genetic variation. Some of the traits are passed down from parents to descendants and are heritable. Witrynaadaptation, in biology, the process by which a species becomes fitted to its environment; it is the result of natural selection’s acting upon heritable variation over several generations.

WitrynaThe mechanism that best explains evolution is a phenomenon known as natural selection. Natural selection is the process by which certain inherited traits—such as the color of a fish, height of a person, or shape of a leaf—are favored within a population. A population is a group of organisms that mate and reproduce with one another.
