Survival is all a primitive people would gain from having bodies adapted to their environments. Ultimate potential is intellectual in humans, which has nothing to do with environment or anatomy.
Have I said that already?
Chasing your food (not much of an accomplishment) will bring you many strange places, and that's assuming that there was only one point of origin.
It is now.
You mean human ****ing. And I guess they'll have to be insulted. Anyone can ****, and it seems that's all they did for their first 30,000 years.
Human beings are the apex of an evolutionary trend in which emphasis upon developing the body for survival shifted to emphasis on development of consciousness for that purpose. The body and the tasks it can perform are necessary to support the mind and to execute it's will, but with only a body, humans would be snacks in a matter of hours. With a mind, however, human potential is limitless, to the point where they are not even required to stay on the planet from which they were spawned.
The only important features of the physical human form are the ability to use tools, travel long distances, and accomodate a brain with high capacity for storage. Commonality of features is more than likely a consequence of stagnation and inertia. The eras in which the breeding required to genetically reinforce the phenotypic sets common to each continent were not exactly paragons of ultimate human potential on display. That distinction belongs to the modern era, which incidentally has done more damage to ancient breeding stock than any other.
Intellect does have to do with anatomy. If the body is injured or if you are very cold or very hot, it reduces the intellect.
Stress of all kinds can reduce one's ability to focus as well.
Migrating was done to chase food, but adaptation to climate was above and beyond that. Besides, if changing to another race had no value as you claim, IT WOULD NEVER HAVE HAPPENED IN THE FIRST PLACE. The fact that it did proves it's validity.
Human beings can exert much power over their surroundings, but not to the point at which they are above the laws of nature, as you imply they now are.
This is a sentence I really like. Well said, only I would use the word "process" instead of trend. Kudos to an excellent sentence. Trend seems more like a temporary thing, while process seems more ongoing.-
"Human beings are the apex of an evolutionary trend in which emphasis upon developing the body for survival shifted to emphasis on development of consciousness for that purpose. "
I also agree with this:
"The body and the tasks it can perform are necessary to support the mind and to execute it's will, but with only a body, humans would be snacks in a matter of hours. With a mind, however, human potential is limitless, to the point where they are not even required to stay on the planet from which they were spawned.
The only important features of the physical human form are the ability to use tools, travel long distances, and accommodate a brain with high capacity for storage."
However, this I see as speculation which has no logical basis.
"Commonality of features is more than likely a consequence of stagnation and inertia. The eras in which the breeding required to genetically reinforce the phenotypic sets common to each continent were not exactly paragons of ultimate human potential on display."
To quite the contrary, I think that they definitely were "paragons of ultimate human potential on display", for THEIR TIME.
Based upon the Baghdad Battery, I would say that human beings achieved far more impressive things 2 thousand years ago than they do today, relative to time.

If human beings could invent an electrical battery 2000 years ago, I think they should have been a lot further along than they are today at that rate of progress. It seems to me that something must have stagnated that progress.
""That distinction belongs to the modern era, which incidentally has done more damage to ancient breeding stock than any other.

I also disagree with this, for reasons stated above, and because humanity has developed technology at the cost of the environment, like loss of clean air, reduction of the concentration of oxygen in the air, due to deforestation, which has a significant very destructive effect on human life.
There is also water pollution and nuclear radiation, not to mention near Eco-collapse due to a genetically engineered crop which could have destroyed food production everywhere had the fields not been burned to the ground once the hazard was realized.
There are a lot of other destructive technologies today which are the result of pursuing technological innovation without the concern for long term dangers, because the focus is on short term profits, rather than long term quality of life. There is a wholesale reduction of ethics today compared to how things were hundreds of years ago and a disconnect to the laws of nature which has brought us to this.
Too much domination of nature by using it as raw materials according to human being's notion of how the world should be, rather than observing how nature works, and working with it and enhancing it for much better results.
Modern "progress" is a short sighted progression to the grave for all humanity.
At least in the past, people invented things that only served to make life better without doing harm to human health.
It's like we all on the Titanic before it goes down into the icy water!
