Somebody is free to develop great technology and science because others make sure that person doesn't need to worry about food, clothing, housing, health care, looking after their kids, etc. That's how society works. You think Newton would have had time for his science if he had needed to toil on the fields from morning till the evening to eke out meager living?
Let's put this back into context. This does not give any more rights to average Joes to claim any of the achievements of Newton, or whatever scientist, and it doesn't imply that they have adapted to their environment either - they have adapted to using tools they themselves will not be able to build. You could teach a monkey to press a button to get food - this doesn't mean that the monkey has reached some high level of enlightenment or that it is superior in any sense - it has just adapted to its tools. So no, the fact that Newton or some other scientist was born in a well off family doesn't imply that his achievements automatically transfer over humanity in general, as much as people would like that to be so. Granted, it does imply that to have time to focus on science your basic needs have to be met at least partially. But I am sure you realize the difference between the two notions.
So at the end of the day the average person is in no way better adapted - unless you consider adapting to your smartphone as a superior trait. In fact you could argue that the average person has regressed, considering the loss of basic instincts, deteriorating gene pool, and deterioration of sight, hearing, taste, smell. A fraction of humanity has indeed developed gene mutations that have to do with greater intelligence and greater physical fitness. But that is a very small minority compared to the general population. The main thing that has changed is your education - which by the way, for the most part gets in the way of more intelligent people - read up on the biographies of famous scientists.
It's not like most of the people of the old would have been any healthier despite living only 40 years if they were lucky. They just had other ailments and troubles. Wild animals also live stressful lives much of the time.
I am unsure what part of my post you're referring to. If your point is simply that medication and food abundance have benefits in terms of life expectancy and general health, then we clearly agree. But that's not my point, is it. You were trying to attribute the achievements of a few individuals to all of humanity, using this to make a comparison to domesticated animals based on some arbitrary metric that you picked to agree with your statement, and somehow reaching the conclusion that looking down on the domesticated animals is justified. I have explained in this very post that you metric could as well be applied to monkeys pressing a button, if the button would provide better health care, and better food, the monkey would in general live longer (provided that also its other needs are met). The fact that you rely on your supermarket doesn't make you greater in any way. What makes you "greater" would be your intellectual and fitness achievements. Attributing achievements of others, to yourself, is simply ridiculous.
I do sense some nihilistic bias in your posts.
Do elaborate. Is it existential nihilism? Moral nihilism? Is it relevant to the point? If it is, point out the instances, etc.
