It seems Hyp, that you have partly misread my post.
With the sentence you quoted, I wished to express my hope that people will *not* start tampering with their own genome *before* they can build a stable society, and thus be more or less safe from their own errors. Otherwise such activity could cause much damage. I expect this because I always expect the best, while taking into account that the worst can happen as well.
Genetic experimentation to replace body parts seems fine. It does not carelessly change the genome of the species. Genetic experimantation to clone a lost loved one is not fine. Firstly it is futile, as this person will not be that person. Secondly it is unethical, as current cloning technologies are a tremendous waste and involve high medical risk for the clone. Thirdly it decreases diversity, and everyone deserves to be unique.
<blockquote><font class="small">Quote:</font><hr>Unless, of course, you assume our intelligence has effectively made natural evolution unnecessary.<hr></blockquote> All evolution is natural, and nothing will ever make it unnecessary. I am simply pointing out that everything with inheritance, diversity and selection tends to evolve. Not only genes, but technologies and ideas too. In fact, while the evolution of our genes is slowing (but will quicken again sometime when people start changing their own genome) the evolution of societies and technologies is currently becoming faster and more important.
While reading this, you should remember that by "faster" I do not mean that people would be quickly changing for better. No. One can become worse just as fast, or swing between improvement and decline faster than usual. Where change takes us depends on our choices. Every road can be traveled in two ways. By "faster" I indicate that change forces us to try out more answers. Which ways we try is our own choice.
<blockquote><font class="small">Quote:</font><hr>Like the fact that educated people do tend to have fewer children than uneducated people.<hr></blockquote> But you are ignoring one fact, Hyp. Education does not depend on genes. It depends on society, economy, technology. It depends on whether the person *could* receive education. If a well-developed society can guarantee those children an education, everything is fine. Nothing is being weakned. True harm occurs if society fails to provide these children with education, pushing itself as a whole further back into misery.

One should always try to avoid it. Yet to answer your question, yes it does demonstrate social evolution. It demonstrates that ideas like "lets mind our own business" and "let them help themselves" are likely to cause harm and backfire at everyone, because we all live on the same planet.
It demonstrates that not giving a damn is an evolutionary dead end. Letting a fire burn until it fries our collective asses. On the other hand, helping one society so it can in turn help others is a good and efficient option. Which option we pursue is our choice. If we choose to let the planet fall apart, it does not change the rule. We will simply become a record in galactic history: "chose wrongly and became exitinct".
The evolutionary part: civilisations who realize this, learn how to repair societies and start doing it - they will last. If our civilisation fails to realize this, fails to find stable social and environmental models, or fails to apply them, mankind will finish itself in wars and environmental disasters. If we realize the need to defuse such problems, we may continue.
Each day, each year, already for millennia, we have been trying countless ways to reach a sustainable and stable society. We have found many good practises, and written them down. We have learned about human nature, and sometimes even learned that this knowledge must be applied. Sometimes, very rarely, we have even applied it successfully. If you want any demonstration of social evolution, consider this one.
Yet nothing but trouble comes easily. For every right decision, people will make a wrong decision. But if societies record their right and wrong decisions, and try to learn from them, they will eventually improve. Not easily and never quickly. Everything which may succeed may also fail.
I believe I am correct to say that genetic evolution is becoming irrelevant, and social / technical evolution relevant. That was my point, and nothing more. Where this evolution will lead is our choice.
You are correct to say that evolution does not help us. I have never said that it should - it may just as well help another planet. We can become an example of success or an example of failure. What we become depends on how we choose.
