The trait must have caused the organisms to evolve because it made the organisms that had it more fit for survival. If the organisms changed due to another mechanism, such as genetic mutation, it was not due to natural selection. Natural Selection and Darwin's Theory of EvolutionPostulates of natural selection. Explanation: Early in development, all vertebrate embryos are remarkably similar. The similarities among the embryos imply that the development of all vertebrates (having a backbone) evolved as new genetic instructions were placed on Top of older ones. The chick embryo is on the right.Natural selection is the process through which populations of living organisms adapt and change. Individuals in a population are naturally variable, meaning that they are all different in some ways. This variation means that some individuals have traits better suited to the environment than others. Individuals with adaptive traits — traits ...Identify the four postulates of natural selection.

February 6, 2015 – Natural selection: Darwin’s four postulates. In the past few days, we’ve gone over how evolution can occur through mechanisms like mutations, gene flow, and genetic drift.

Natural selection obviously lies at the center of Darwin's theory, but we must recognize, as Darwin's second key postulate, the claim that natural selection acts as the creative force of evolutionary change.

It is a common misunderstanding that evolution includes an explanation of life’s origins. Some of the theory’s critics complain that it cannot explain the origin of life. The theory does not try to explain the origin of life. The theory of evolution explains how populations change over time and how life diversifies—the origin of species.Species change over time. Postulate 2. All organisms are related by descending from a common ancestor. Postulate 3. Evolution is gradual. Postulate 4. Evolution leads to new species. Postulate 5. The primary mechanism for evolution is natural selection.natural selection acts on traits, mutations for advantageous traits are more likely to be passed on to the next generation, and natural selection favors some mutations. In the lab, Nachman examined dark mice from two different populations living hundreds of miles apart. The mice looked nearly identical.
