Why haven't we evolved to be immortal?

ah... no

just understanding the genetics of aging is all we need

Baftan, I enjoyed your post.

In my opinion, 'immortality' is a very scary thought. May be too much of a cliché, but I agree that our short life spans are one of the qualities that makes us 'human'. Honestly, it makes me comfortable to know that I am going to vanish one day.
Thinking that everything is an experiment and a process makes the whole thing beautiful for me, that nothing's stable.

I know it's not related to the OP or any rational thought, but I am sure most of you are familiar with Anne Rice novels. In her novels, she some sort of 'reads' human kind as species by telling of another, imaginary immortal one. It's fantasy literature, but I think it gives some sense of being 'immortal' between the lines. It's not appealing at all.

 

We live longer now because we have pathogen free drinking water now.

 

We would be competing for resources with our own grandchildren. Nature has found that species tend to survive better when they are evolving through sexual reproduction than when the individuals just live for all eternity.

Also everybody gets parasites eventually and dying helps kill off the parasites and some other diseases.

Another example of this is grandparents. Why should women go through menopause and still live? They can no longer reproduce, so what evolutionary advantage are they? Turns out they provide a survival advantage to their offspring by contributing knowledge, and being able to care for children. So evolution has worked to lengthen our lives.

 

because humans have a life expectancy determined by their body parts.

 

There is research to find ways to combat aging and assures healthy longevity .
The research is still a new born baby and it takes time .
I believe in science and humans might one day live up to one thousand years.
From there new facts will appear about life and death and we might prolong life by more years . With science....yes...we...can !.....

How could we live at a sub-atomic level? What do you mean by that?

compared to a housefly, I am immortal. Its all about perspective.

I'm only 43 because we have a 12 month calendar. If we had an 18 month calendar, I'd be a super sweet 28. And that is what I pretend.

Or rather, that is my perspective on aging.

 

This is called the math backward .......if there is such a thing.....:shrug: .
A month is a month by a linguistic definition and mathematical counting .
Conclusion : you are NOT immortal .

 

Lol... did you really have to emphasize the "NOT". LOL. Sounds so funny....:roflmao:

Peace be unto you

Th answer to that specific question is no - death was never selected against in the long history of evoution.

I wil leave it up to you (or perhaps others have already answered) as to why that was

 

So that's evolution? Or is it technology?

It is pure science and nothing to do with evolution .
