All you really need to understand at this point, despite your obvious reluctance to, is that Darwinian evolution applies to gradual changes in whole populations, species, not individuals. Changes and adaptions in species are gradual and the result of natural pressures from the environment. Gazelles (say) have evolved their speed and agility because those that aren't so quick get selected by cheetahs as food, natural selection in action. The genes of successful individuals will make it to the next generation.
:sigh: The term "Natural Selection" should be clear enough for most people I would have thought, do I really have to spell it out?
The individuals that are less well adapted will naturally get selected first and thus eliminated, leaving behind the "fittest".
Selection that is the result of intelligent choices is known as "Artificial Selection".
General principles Natural variation occurs among the individuals of any population of organisms. Many of these differences do not affect survival or reproduction, but some differences may improve the chances of survival and reproduction of a particular individual. A rabbit that runs faster than others may be more likely to escape from predators, and algae that are more efficient at extracting energy from sunlight will grow faster. Something that increases an organism's chances of survival will often also include its reproductive rate; however, sometimes there is a trade-off between survival and current reproduction. Ultimately, what matters is total lifetime reproduction of the organism. The peppered moth exists in both light and dark colours in the United Kingdom, but during the industrial revolution, many of the trees on which the moths rested became blackened by soot, giving the dark-coloured moths an advantage in hiding from predators. This gave dark-coloured moths a better chance of surviving to produce dark-coloured offspring, and in just fifty years from the first dark moth being caught, nearly all of the moths in industrial Manchester were dark. The balance was reversed by the effect of the Clean Air Act 1956, and the dark moths became rare again, demonstrating the influence of natural selection on peppered moth evolution.[4] |

Since you clearly aren't even slightly interested in rational scientific conclusions from facts and evidence then your empty assertions here are pretty worthless.
