All species have genetic variation. ;D
They are the selective agent in natural selection ;)
his development in science is that he created the natural selection
One was Darwin's theory was the process of evolution by natural selection and the second one was Lyell's theory was that animals can adapt and change their traits to fit the environment.
Randomness.
An organism with a charecteristic that is more helpful to its survival will be more likely to survive and breed than one without that characteristic.

Natural selection is one of the mechanisms that shapes adaptation and enables evolution.
Which polar bear will not benedit from natural selection
Directional selection
his development in science is that he created the natural selection
Natural selection is the process by which certain traits that provide a reproductive advantage become more common in a population over time, leading to evolutionary change. Evolution is the overall change in a population's genetic makeup over successive generations, driven by mechanisms such as natural selection. In essence, natural selection is one of the primary mechanisms through which evolution occurs.
It is an example of Natural Selection, Modern Theories of Evolution.
Variation in the organisms under selection. In both artificial selection and natural selection there must be heritable variations that have the possibility of being in the case of artificial selection what the selector wants in the organism and in thje case of natural selection survivability and reproductive advantages.

Neither artificial or natural selection. Chocolates, even variant chocolates, do not fit the criteria needed for either type of selection. No fidelity or fecundity.
The three patterns of natural selection are directional selection, stabilizing selection, and disruptive selection. Directional selection favors individuals at one extreme of a trait distribution, stabilizing selection favors the intermediate phenotype, and disruptive selection favors individuals at both extremes of a trait distribution.
Randomness.
