natural selection
Adaptation is the result of natural selection.
By the way, this article is not talking about animal breeding issues or human breeding issues, which is not my concern, not this moment. It is about how nature uses its laws to decide intelligent living thing's existence and how human can adapt. It is not the natural law --- "free competition natural selection" is wrong but the specific meaning of it at the present social system development level is not applicable to the changed system, though its general meaning still apply. The usual meaning we use is the specific meaning of it --- competition in a process. That determines who win and who lose in a process. But the general meaning of "free competition, natural selection" includes system selection that determine processes connections and final survival. Natural selection has different forms and different selection levels, higher level selection always are more important and more decisive than the lower level ones. The natural selection we usually talk about is the process selection. It is a lower level selection on strategic and tactic level. This is the specific meaning of natural selection; it is widely used in game theory, social biological and social behavioural studies. But the general meaning of natural selection include all forms and all levels of selection including system selection which is a higher level selection which can override process selection and be the decisive selection that decides final survival. Use value has power and it only can be converted from real value --- natural value which is natural resources. Under natural process over use resources make more power and power is the hard force that always prevails. Competition pressure and natural process will always tend to cause more over use of resources but at this moment of social development, natural mechanisms on this process level cannot function to check human activities and resources are facing exhaustion and environment loading capacity are facing limit. So the natural development of this process is human life chain cut early --- extinction (natural mechanisms only on this process level can check human destruction). This is an example of winning a competition in a process does not mean "win" in a general meaning --- they extinct. The only way to achieve the general meaning of "win" is use rationality to overcome the process disadvantage of instability to win natural selection in system level --- recognise and obey natural law to use rational thinking directed rational efforts to establish rational social system and carry out rational process in it to connect human with higher level of evolution process and continue to survive. Here, the fittest is the rational beings and nature does select them. When social system evolved to high level and the structure and function become highly manmade, we have to overcome process selection pressure to win natural selection on system selection level to connect our present evolution process to a higher level of evolution process and continue to survive into far future. So, though the specific meaning of free competition and natural selection is conditional in our present social system but the general meaning of it is absolute --- it is an absolute law of the nature and can be applied universally and unconditionally. For instances: though the natural tendency driven natural process (such as self-interested opportunists'' short-sighted behaviour) will always have the advantage of natural process favoured thermodynamic stability and behavioural strategy stability, but when social system naturally developed into a critical point that the system no longer can continue under natural process, those process favoured self-interested opportunists if still stick to their old way of unlimited exploiting the nature, they will be selected out by natural selection that select out the old natural social system with its natural process. Nature selects the rational social system on system selection level that overrides process selection. That is why the endless and unlimited exploitation of natural resources will only win those smart self-interested opportunists a short while of easy life by whether choose cooperative strong development or competitive strong growth, they will all be gone with that social system --- they bring that system down along with themselves and the process that favour their behaviour. As a human being, it is actually themselves that selected themselves out of existence but not really nature's doing. A rationalist doesn't mean selfless, he just smarter --- he can rationalise his short term interest so that to get the ultimate interest --- perpetual existence.

Yes, natural selection is always occurring.
Darwin
Natural Selection
Social Darwinism is a theory about society. This theory states that individuals and groups are a product of natural selection.
Its NaTuRaL sElEcTiOn if you didn't know.
Badly. The theory of evolution by natural selection has to do with the natural world and the selection of individual organisms. Social Darwinism and like ideologies are biologically mistaken as the posit a form of group selection which has nothing to do with evolutionary theory but everything to do with social ideology trying to find scientific respectability.
It is called "social Darwinism".
natural selection
Adaptation does not allow for natural selection: natural selection causes adaptation.
It wasn't! The theory of evolution by natural selection has nothing to do with social Darwinism and to posit such a connection is ill posed. The theory of evolution by natural selection is about individual selection of organisms and has nothing to do with group to group success in economic terms.
Genetic variation in itself does not 'support' natural selection: it is what natural selection acts upon.
Natural selection is what causes adaptation.
