If we get to that stage, we will no longer just be a single human race. We will have evolved to the needs of our environments. We will be a link in the chain of evolution

But no, it doesn't bother me at all. We are alive for the birth of the technology age, and that is amazing

That's not the way evolution works

That's exactly how evolution works... favourable(some not so favourable) traits are bred through generations until they are common amongst the population.

Correct, but that has nothing to do with "the needs of our environments"

Actually, yes, it does.. how do you think we developed different human traits catering to the need of the regions they first emerged?

Evolution prefers traits that allow the species to better survive in the environment. There is no "need of the environment" involved.

What is it you think the environment "needs" in order for a species to evolve.

I suspect you meant to say humans have evolved to be better adapted to our environment. If so, your phrasing is very non-standard and confusing.

The "needs of the environment" is why we we develop the traits that make that survival easier.

For instance, people who have lived at high altitudes for generations tend to have larger spleens and looped capillaries because that is what was needed to live easier in that environment

The environment doesn't need anything. That's not how that word is used.

Just like a person does not go to the store for "the needs of the store", a species does not evolve for "the needs of the environment".

Additionally, a species doesn't evolve due to specific environmental "needs" (whatever that means). It evolved when a mutation provides a higher chance of offspring that survive. That can have nothing to do with "need".

Our needs..

We will have evolved to the needs of our environments

Im not saying the environments needs..

This literally means the environment needs something, and we evolve to meet it.

The sentence "Hank provides for the needs of his children" means Hank's children have needs, not Hank himself. Same thing here.

It may not be what you meant, but it is what you wrote.

Additionally, "need" is a vague term which does not capture the driving force behind evolution.

Imagine a species that has all its needs met. There is more than enough food for the current population, no predators, but the species is limited to one offspring every 10 years, and typically have 30 years when they can produce offspring.

A mutation occurs, and this new member of the species can have offspring every 5 years. In this case, even though all of the "needs" of the species are being met, that mutation will likely out-compete the trait of having offspring every 10 years. The species will evolve, even though all its "needs" were being met.
