do we have a colapse about natural selection witin Homo Sapiens?

Question

Homo Sapiens created Hospitals, Drugs and doctors. It created new life style were people without bright can reproduce without boundries.
Are "freedom" and "we are all equal" discourse really good to humanity? I mean, weak links are reproducing and creating more weak links.
Humans had jus interruted natural selection situation and created a new set of rules to build new breed of ultraspecialized humans. AWe know that all ultraspecialized species are faded to disapear.

We are not equal. We are different. People all around world have different treatment; This is a question about genes and not Phylosophy or culture.

Answer 1

yes. i am a bio major, so i have long known the obvious fact that the drawback of medical care is that the human race is degenerating - we are getting more and more unfit with each generation, and even some people who are seriously sick with conditions that are for sure hereditary do not think better than to pass them on their children just because it feels good to be biological parent (such selfishness makes me truly disgusted each time i hear of such case, to me it is the worst of crimes, crime on the innocent baby instead of love, while talking of motherly love) but the extent of this process of genetic deterioration had dawned on me fully the other day: See, i have a gecko and a chameleo and they love flies. so i buy maggots (sold as fishing bait) and let them grow into flies. First time i did this i was surprised to find how dull, clumsy and simply unfit the flies are (but they are larger than wild) I simply expected flies that dont differ from the wild ones, but these u can catch all of them in midair without problem. Why? because all of them survive, they are not subject to natural selection for many generations in succession. The are maybe selected according to the ability to survive in damp stale air of the containers. So i said to myself, yes, you must face the truth, we people are just as fit as these pathetic flies. Or, look at the ability animals can heal their injuries - just realize that once we were able to do the same! And this gonna be worse with EVERY generation. Allergies, infertility, all this stuff.

IF the human race was really on the top, rather than just very conceited, we would have done something about the fact that some countries are starving, while elsewhere people weigh 200 kilos and die, and the gene pool of developed countries goes to hell fast - see i am not advocating the comeback of natural selection, but only what feels to me as basic responsibility and care of everybody towards their children and grand grand children. If XY complains of a sickness, why at the same time they go completely undisturbed that their child will "enjoy" the sickness as little as the XY does?

Answer 2

No, Natural Selection does not simply consider the genotype in regards to ensuring the survival of the organism. Natural Selection is concerned with the interaction of the environment on the genotypes that prevail. I.e. it is the environment that determines how or if genes are expressed. I.e. If I had the genes to be really tall but there was little food that I could eat then I probably would be short.

The point is just because we have affected our environment does not mean that we are not under selection pressures, its just that the pressures have been changed or become less intense and more intense in some areas. With the media for instance we all have a selection pressure to be thin and Jewish inorder to get be succcessful in our love lives.

Answer 3

We have put up a few more rules in addition to the ones governing natural selection, we can't shut it off, we can moderate some of it's harshness, but it's always trimming up the loose bits.

The only measure of evolutionary success is reproductive success. who's the weak link by that measure, the literate wealthy child free or the ignorant trailer trash?

Equality refers to equality of opportunity, which has never actually been instituted.

There will never be total equality so long as there are different levels of ability among different individuals.

Freedom is supposed to guarantee opportunity to rise, and indeed fall based on your merits or lack thereof.

Answer 4

Homo Sapiens is not the end according to Darwin.Further changes may happen.Remote control machines,automatic transmission systems etc may reduce the size of hands,legs etc.The height of man may decrease,head will become big(more use of intelligence),small hands legs and perhaps like a football.But they will be super human being.A new race is coming replacing our species.Beware!Sex for reproduction may not be essential and for pleasure only.Babies will be produced in factories!!

Answer 5

You are absolutely right.

The laws of natural selection are being altered by the lifestyle the Homo Sapiens chose to adopt. However, Darwinism in its purest form is not being violated because it stipulates "survival of the FITTEST".

Charles Darwin intended FITTEST to mean "the organism best able to adapt to the demands of its environment", so although you may perceive natural selection as no longer applying, humans are merely bending the definition. "Fittest" has always encapsulated the idea of the organism able to produce most offspring, so applied to todays society, this means is likely to mean the individuals with most time to raise children (usually the unemployed). So Darwins "specialisation" may be contrary to your perception of what SHOULD be defined as specialization, simply because it is ANY adaptation that renders one organism more likely to bear living offspring means it is the "Fittest".

The real irony of the whole human situation, is that those with the intellect and power to override classic Darwinism (i.e. the scientists who design the drugs which improve live for the general populus) tend to produce LESS offspring (because of the demands of their work). However, the less intellectual with more menial jobs (or no jobs atall) have their lives and quality of life extended by such drugs, leaving them more time to produce larger families. By definition (and the laws of genetics) these numerous offspring are likely to be of lower average intelligence.

So by our own hand, we have reached the pinacle of our evolution, as we are now committed to "dumbing-down" our population. Which is why my first line to you reads "You are absolutely right".

Answer 6

"Equal under the law" is good, but that doesn't mean people are, or should, be equal in fact. And "Freedom" isn't the problem. We actually don't have enough. What we need is freedom to fail, then we can keep up with Nature's learning curve.

Answer 7

By allowing weaklings to survive, you think we may be screwing up the human gene pool?

In some ways that could be true, but some people who aren't physically strong are mental giants, and that could be what saves the human race in the end.

Answer 8

Nah. Although we have laws saying everyone has equal opportunity to do things, in reality many people don't take advantage.

Answer 9

the same old rules. rich against poor. big bullies like America against N.korea. why not throw all the nuclear waste into space.

Answer 10

Yes, because we look after the week when in the wild - normality - they woudl die or be killed, conquered or eaten.
