Genetic mutation and variation are the main drivers of phenotype characteristic differences among species. The organisms in a population that are better suited to survive and reproduce, survive and reproduce (propagate) more than the organisms that are less suited. Add to that sexual selection and you get a wide variety of species that seem to have been designed but were sculpted by blind processes. The process of genetic mutation and variation is not a hypothesis but a scientific theory that is based on observable facts and evidence.
This process is called natural selection. It is the mechanism by which traits that provide a survival or reproductive advantage to an organism become more common in a population over time.
Natural selection can only work on genetic variation that already exists. So mutation comes first, then natural selection.
It hasn't. Natural selection is a key part of the ecosystem itself.
Natural selection is the mechanism primarily responsible for the development of today's biodiversity.
No, natural selection works on that genetic variation presented to it.
natural selection for example is a peppered moth.
Its NaTuRaL sElEcTiOn if you didn't know.
Adaptation does not allow for natural selection: natural selection causes adaptation.
The prefix of natural selection is "natural" and the suffix is "-tion".
Genetic variation in itself does not 'support' natural selection: it is what natural selection acts upon.

That selection was natural.
Natural selection is what causes adaptation.
No, natural selection is the mechanism that drivesevolution.
