what is logical explanation for events observed in nature
No. They function through the exact same mechanisms. The only difference is what controls the environment: whether it is in human hands or left to nature.
Vestigial structures do not harm the organism. Nature selects against only harmful traits.
In brief, those similarities Darwin observed suggested that those animals that he saw in fossil form passed along useful traits to modern animals. These traits had been selected by nature (natural selection) because of their value to newer generations.
Yes. Evolution is routinely observed in both labs and in nature.
Humans directly affect artificial selection. They do this by selecting the specific traits that they prefer which they cannot don in a natural selection.
Natural selection usually causes a species to change gradually
Natural Selection
natural selection for example is a peppered moth.
theory of natural selection
Selective breeding is known as artificial selection because you are selecting the mates instead of letting them select their own. It's bypassing nature so it's classified as artificial. Outside persuasion that directly effects the outcome of the natural selection.
Natural selection explains the process of evolution: evolution by natural selection. It basically means that species with the highest fitness (survival rate) will live, and be selected by nature for the characteristics they possess that make them more apt to survive. Because of natural selection, evolution occurs.
Phenomena is plural for phenomenon meaning A fact, occurrence, or circumstance that is observed or observable. Fog is a natural phenomenon in nature meaning exactly that. It is a natural occurrence that can be observed in nature. Think of it like a rainbow, wave on the ocean, and or even a volcano! These are natural occurrences that amaze us and can or have been observed. Fog is amazing to see. For example, you can stand right in the middle of fog and yet you can really feel it. All you feel is the chilled crispness of it. Fog is a natural phenomenon in nature!
Nature plays no direct role in artificial selection. That is the difference between artificial selection and natural selection. Nature does play some indirect roles in artificial selection. One indirect role is in providing the organisms with which one beings the artificial selection. Another is in influencing the choices of the organism performing the artificial selection.
It is possible to have artificial selection in nature because of naturally occurring changes in the environment. These changes can greatly modify the organisms in question.

Natural selection. Which ultimately leads to evolution.Or God. Depending on your beliefs.
