My question was totally serious. These are legitimate questions for me. After your apropos thoughts on why organisms have a self-destruct process, I was hoping that you would have some thoughts to my real concerns.
I know why we age, why they don’t, and the dynamics of it. But in the event that jellyfish do not any longer have sufficient predation, I would imagine that they proliferate, destroy their own resources, and the equilibrium of all ocean life is messed up.
Or maybe everything will perish and all life will return to the sea, with a few primitive sea organisms, and evolution will begin over again. And that will just happen until our sun blows up: out of the sea, back into the sea, out of the sea, back into the sea.
I have also been considering this notion. Weren’t humans once primitive sea organisms? However, it was a different earth that we evolved into. The new earth will be so different after we leave it, so contaminated and defaced.
Yeah, that’s religious. I’m rolling my eyes now by the way. I believe in natural selection. Especially when it comes to huge biological events like aging. Especially given the fact that I clearly discerned an advantage in the aging process, it is fair to assume that is why it exists. Not even the mods of this board have any class apparently.
Life expectancy for the very great majority of human existence was less than half of that in the modern world, even leaving out infant mortality. Anything that gave an advantage to breeding rates over that period would be favoured, no matter what the longer-term effects were on the organism. Something that kills you at 60 has no noticeable deleterious effect on a gene’s selection, when disease and bad weather and wild animals are selecting for things at half that age.
Alternatively, if you have evidence that old age was positively selected for due to massive global overpopulation near-extinction events, I’m open to consider that. Odd that it didn’t happen to jellyfish, though.
You are bringing a particular time span of a particular species into a universal discussion of life. I mean, what I am talking about is just common sense. Even the first Wikpedia article of biological aging mentions:
"August Weismann was responsible for interpreting and formalizing the mechanisms of Darwinian evolution in a modern theoretical framework. In 1889, he theorized that ageing was part of life’s program because the old need to remove themselves from the theatre to make room for the next generation, sustaining the turnover that is necessary for evolution.[1] This theory again has much intuitive appeal, but it suffers from having a teleological or goal-driven explanation. In other words, a purpose for ageing has been identified, but not a mechanism by which that purpose could be achieved. "
The mechanism is the disintegration of what we now call telomeres.
The argument could be made that animals die because of natural predation so nature would have no reason to evolve this adaptive trait. But consider predatory animals, the kings of the beasts, like lions. Animals that perish rapidly because of predation, when taken out of nature, actually have immense life spans, like turtles, jellyfish, lobsters- the trait is not dominant in them, aging. The animals that do not have many predators would have benefited greatly from this adaptive trait, aging. Aging would allow for genetic variability, because the older an animal got, so it would gradually lose its reproductive capacity, it would get weaker so another leader could take its place, etc. Eventually, if it wasn’t killed, it would die, making room for new competitors in the Colosseum we call life. I think this addresses you, Humean.
The mechanism that is missing is that whereby telomere disintegration is selected for - evolutionarily preferred. If the argument is that without it you get overpopulation and repeated near-extinction, the question is how the aging subpopulation survived the overpopulation of the immortal group merely by virtue of dying faster - this is a question for any mechanism, of course. The argument that only those who died earlier evolved fast enough to become ‘higher animals’ is only post hoc ergo propter hoc - no mechanism of selective preference is advanced.
Why do you think we would not want to pursue happiness just because we are immortal? I didn’t read the end of it because you didn’t grab my attention, the first few questions you asked in regards to why would we want to do anything just simply has obvious answers. For one, if I was immortal, I wouldn’t want to sleep under a bridge for eternity. Of course I would want to learn and continue learning and why not?
Karaoke and Cold Lazarus’ offered an interesting solution to the problem of human mortality in the character of Daniel Feeld, played by the inimitable virtuosic Albert Finney. I don’t think anyone has ever tried that in real life, but I’ve also seen similar scenarios in other sci-fi shows. After thinking about it, I decided that I don’t think I’d like that solution at all.
Warehouse13 played around with cryogenics this season, which reminds me of that other solution of freezing yourself and hoping to be awakened again after humans have figured out how to keep you alive. I don’t think I’d like that possibility either, but it beats Daniel Feeld’s option.
well…it is your choice ww111angry…im not sure what you want me to do about that
learning is not possible without death ww111angry as said within the op- physical immortality is impossible because it would be existence without death but existence itself has death within- as stated within the op…therefore once again physical immortality is not possible within existence…it appears you do not fully understand the idea of physical immortality
