simply put, only the strong will survive
Everywhere where life exists.
Genetic change is necessary for natural selection to take place
Natural selection is one of the 'guiding' principles of evolution.
yes natural selection takes place without human control. In natural selection it is the environment selecting the traits/alleles. However there is something called artificial selection which is evident in dog breeding. In that case humans select for the traits. Artificial selection can have detrimental effects on a population though. Some dogs have been selected for being very small and having a flat nose. These dogs are so small now that they cannot give birth naturally and have no use of their nasal passages
natural selection
Adaptation is the result of natural selection.
Charles Darwin described this as "survival of the fittest". It is the central mechanism by which evolution takes place.
To the environment.
Natural selection is the nonrandom process by which biological traits become either more or less common in a population as a function of differemtial reproduction of their bearers. One of the main processes by which natural selection takes place is the competition over resources. The larger the population in a certain area, the more competition takes place. In the long run, it doesn't matter wheather or not the area is overpopulated; within any and every population, competition over resources takes places, so, in turn, natural selection does, too.
Disruptive selection.
Genetic change is necessary for natural selection to take place
Natural selection needs competition in order to take place.
The book, On The Origin Of Species, " suggested " that organisms evolve through the process of natural selection. The nonrandom survival and reproductive success of randomly varying organisms

In Darwin's time, it would be classified as "natural" selection.
