Whereas bacteria and viruses have rapid generation times and are rapidly adapting to the things we use to kill them.

In nature most things don't die of old age. Other factors are more important to the survival of an animal for example.

One of these factors is the development of cancer because of certain chemicals and radiation in the habitat.

Cancer cells usually duplicate much much faster than regular cells which is why a method of killing off cancer cells has positive evolutionairy pressure.

This method are Telomere which get shorter every time a cell divides. The problem with telemores are that they also limit the lifespan of regular cells. This is not a problem in nature since most things die before this comes into effect anyway but we humans live such a long time that it actually has effects like organ failure and wrinky skin.


This is ONE of the factors but I think it's a mayor one. If we find a way to extend the Telomeres and a way to correct flaws in the DNA we would live veryyyy long lives.


I'm not scientist but is this somewhat correct and plausable?

>> No.5478835

as an ID guy, I don't think entropy was ever intended to exist in the universe.

"what is the evolutionary advantage to ageing?"

What if the advantage wasn't for the person who is ageing, but rather for the community or family of the one who is aged?

1) The ageing exist for those around them. to communicate lessons of success or failure as to allow the younger generation either to improve their survivability, or increase their survivability.

But even in this scenario, there is a choice given to the younger generation to learn within the experience of the older, or not.

2) To ensure the transmission of culture and appreciation of art and the humanities.

History is told by those who survive it, and it becomes a part of the next generation.

As for art and the humanities, I would not have an appreciation for different kinds of music and film and story if it were not for the generation ahead of me taking the time to share it. From Danny Kaye and Frank Sinatra to Creedance Clearwater Revival, I would have dismissed these artists as old an irrelevant if it were not for older generation.

3) To allow us to show humanity and compassion to those whose strength is growing weak.

As a younger generation, we have an obligation to help the older generation live long, well, and collectively prosper.

Encouragement, time, and caring physically and emotionally, are part of the design of the human culture.

A few weeks ago, a friend of mine who is twice my age, stopped by my office for a visit with a graduation book from a WW2 flight school. We visited for almost three hours as he showed me pictures of the training aircraft he flew, up to the P-51 mustang he flew over Italy for 53 mission. More than that, as he turned the pages of the graduation book, with pictures of the men he flew with, he recounted their stories.
Engine failure, missing, shot down and killed, sickness, cancer and the list went on.

Age well my friends...

the advantage is in clearing away the dead weight.

old people are slow to learn, and resist change. the thing that makes humanity so good at surviving is its ability to adapt to change.

aging and death are what kept the leadership pool from becoming too senile.

i mean, imagine if people from the 1500's were alive today, and were in charge. the current bunch is pretty pathetic, but add another 400 years to their age and they'd be hundreds of times worse.

Like this man says,Advantages and disadvantages can be drawn from the fact that we age, but that doesn't mean that aging has anything to do with evolution.

Considering basically all life we know of does in fact die irregardless of it's evolutionary progress, ie, an amoeba will die eventually as surely as a blue whale will, you can't really say we've evolved to die on purpose to avoid cancer.

>you can't really say we've evolved to die on purpose to avoid cancer.

You got the idea wrong. In "nature" things die before they get old enough to get killed by the aging properties of having a limited length of telomeres.
Aging is a side effect of something that is VERY beneficial to survival that usually doesn't come into play because something killed the organism beforehand.

This and the fact that we accumalated heavy metals and other stuff during our lives make us age.

>>5479047
Are you literally retarded? At the time the concept of telomeres developed you virtually NEVER died of old age. The benefit of not diyng of cancer as often GREATLY outweighs the fact that you might die of old age since no one ever died of old age. People died of breaking their leg or having bad teeth or getting eaten.

Your assumption that complex forms of communication is what gives rise to an animals ability to be self aware is wrong. We already know that various species of parrots, porpoises are self aware.

Why do you assume that a wolfs howl or a birds chirp is not a complex language? Because it isn't as complex as humans? Because they don't have an alphabet? Or because you simply don't understand the communication system they are using?

How does a pack of wolves know how to surround and effeciently kill prey? How do birds instantenously take off and stay together as a flock?

You think because animals communicate differently, because there "language" is not as "complex" as humans, that they are not self aware.

First we have to separate aging and death. Aging is something that doesn't exist for some animals for reasons I'll get into soon. Death is something that's unavoidable; no matter how good you are at surviving, something is eventually going to kill you. The stronger, smarter, and tougher you are, the longer you can postpone it, but statistics say that eventually something is going to get you.

To understand why aging exists, you have to give up the concept of 'Survival of the Fittest.' Nature doesn't care that you're the best on the block, it rewards only the ability to feed yourself and produce babies. If you can do those two things, it doesn't matter what horrible traits you have there will be more of you.

Basically, ask yourself if there's any environment where being ageless is a mandatory trait. There are none. Two animals that live 70 years and 700 both have ample time to have children. Both animals are going to succeed, and since the animal that lives 70 years is going to be subjected to more genetic change due to a greater number of generations, it's descendants are going to be more diverse, and so make up a greater number of the species in a given environment.

Basically, nature is blind and doesn't care how much of a 'winner' you are. It doesn't care that you take issue with the fact that you were given only 50-120 years to live. As long as you produce children, your genes that cause your short lifespan will be passed on.

Evolution is about breeding, not surviving. We have kids and then we stick around long enough to protect them and help them into their adulthood, so that they can continue to spread our genes. This is opposed to some animals who engage in shotgun breeding, pumping out as many offspring as possible and not caring for them nearly as long.

We die because we have "bad" genes that activates when we reach a certain age and starts to corrupt important functions in our bodies. But as long as we have the time to procreate before this happens it will not be that big of a disadvantage having these genes.

So then why do decidedly inferior traits exist? Humans that didn't use the same hole to breath and swallow wouldn't suffocate on their food, and thus more of them would survive and live to produce more of themselves.

The answer is simple; humans that use the same hole to breath and eat have no selective pressure to evolve away from using the same hole for both. They manage to produce children anyway.

It's more 'survival of everyone that meets the bare minimum.' Darwin simply wished to see what his culture thought admirable in nature, and what he saw admirable was self-improvement and competition. He once predicted that 'the savage races' would be out competed and exterminated by the civilized ones, and we all know how that prediction is faring.

The truth is, nature is mediocrity. We see the same forms, over and over again, that never truly get better then previous ones. We don't see a race to the top, but rather creatures doing the absolute minimum to get by.

Not being a troll, but just asking a question from another point of view.

Questions the OP asks:
1) why...? There are two responses possible. Impirical and philosophical.

2) why do we grow old and die?
Impiricaly - entropy
Philosophically - it should warrant an answer from a point of view. Im not asking anyone to agree with my point of view, but rather politely offering it.

3) What's the evolutionary advantage? The question implies that aging is a disadvantage. That is philosophically a point of view question, one that seems to be stating that aging is bad.

A response could be, let's examine if aging is bad. At minimum because we travel through a space time continuum of 3 directly observable dimensions, a 1/2 dimension of forwardly progressing time, and the inferences of 2 or more different dimensions on top of those, aging is normal.

I simply asked a question that should be considered with an answer, what if aging is not about us, but rather what if my aging is more about those around me ( or you)?

Sometimes our point of view will deny us the proper framework for which to formulate an answer.

Scientific observation and discovery is about questions, some of which carry a philosophical component because of our point of view.

4) Why do we die?

Cellular senescence (which ultimately brings the problems of old age) is a way to prevent cancer.
Telomere shortening is a way this occurs, but it can also be induced through p53 in response to excessive damage to DNA or when certain oncogenes (Myc and Ras) are too active.

>> No.5481128

>>5479776
Telomerase?

>> No.5481559

I would make the argument that cellular death exists because there isn't really a biological advantage towards living forever. Evolution doesn't really always move from worst to better, from "primitive" to "complex," it often takes the path of least resistance. For the majority of life, a long or infinite lifespan is nowhere near advantageous as producing quality offspring (or a large quantity of offspring). The longer you are alive, the more your DNA is damaged by your environment (everything from free-radicals, to cosmic radiation, to the wear and tear of staying alive). The more your DNA is damaged, the less likely you are able to produce quality offspring. The only way your body would be able to stay alive indefinitely is if it underwent a complete DNA revamp every few decades. All your DNA would have to be checked for errors, broken pieces would need to be fixed, and your DNA would need telomeres added to the ends. These are all resource intensive from a biological and evolutionary perspective, and the resource would be better spent on producing more offspring and/or better quality offspring.

entropy isn't an answer, because life is reduction of the entropy of a system by more entropy in the environment.
The cause of death is the decrease of this capacity with time.
There is no evolutionary advantage to ageing, it's just useless to genes to stay in the same vehicle. Because most of the organisms doesn't die from ageing.

If you mated only the oldest people in a population perhaps but woman can't reproduce past 45-odd years and you can't predict if they'll live to be really old so. Plus older people's sperm is more likely to have genetic defects, so this idea is highly impractical.

I would beg to differ. People who can live longer has a larger chance of reproduction than people with shorter life span; therefore, we can say that as generations of human-beings come-by, the life-span of people should be longer. However, the trend is that people's life-span is decreasing. Although the life-span recently increased slightly due to less wars and advanced medicine. But, the increase was due to more people having access to better life rather than a genetics change.

You start mating 45yo humans, and only keep the good shaped human produced, and you mate them when they are 45 during such a long time that they will become capable of reproducting at 46 (of course, kinda arbitrary numbers), then you go on and on, and you will end with populations where everyone need to be 100yo, 200 and more.
This process might take millions of years.
Slowly approching immortality.

Ok, if you selected the women who go through menopause at later than average. However the genes for going through menopause and the genes for living longer aren't necessarily the same, I highly doubt it would work the way you are talking about it.

then people will die in age to reproduce, keep only the older and continue.
the question is : is there a limit?

in fact this is a litle wrong, but if you only mate the oldest people who can reproduce, you will pull up the reproduction-limit age.

Let's forget mechanical immortality that can be developped in a fraction of a fraction of that time.

How do you intend to maintain this eugenic program in light of FUCKING HISTORY ?

You're the culmination of ~15 billions years of matter; the universe is saying, "You have a century to live in my realm."

Of course, this is theoretical.
And the first problem won't be the maintain of such a program, but establishing it, in regard of the numerous not-good looking child that this process implies.
