English translation:the conscious [selective or artificial] breeding by human beings
Explanation:
Genetic variations can be attributed to two factors. One is natural selection (from the natural environment) and the other factor is artificial or selective breeding that is achieved consciously by human beings.


Natural selection is the gradual, non-random, process by which biological traits become either more or less common in a population as a function of differential reproduction of their bearers. It is a key mechanism of evolution. The term "natural selection" was popularized by Charles Darwin who intended it to be compared with artificial selection, what we now call selective breeding.

Natural selection is one of the cornerstones of modern biology. The term was introduced by Darwin in his influential 1859 book On the Origin of Species,[1] in which natural selection was described as analogous to artificial selection, a process by which animals and plants with traits considered desirable by human breeders are systematically favored for reproduction.

The basic premise of eugenics has never been disputed ever since Galton invented the term about a century ago. This, as we know, entails conscious selective breeding within our own species for certain perceived good reasons as opposed to the more accidental happenstance of natural selection
