Basically you are saying that it's better we die so that a new generation can come and then die for others come around just to die to make way for others.
Whats the purpose of that for the individual? Why is that by any metrics desirable for humans to die for other humans to come along to just die for yet others?
Well, I can understand how from your perspective it makes sense for you to want to live forever, but from an evolutionary perspective your species is more successful if you die after a while.
If if immortality didn't have negative consequences as severe as stunting an entire species, we'd probably see more species that were capable of immortal individuals. Such species do exist, but not in the Mammal kingdom as far as I'm aware.
But I also think it sets a good guideline. Death improves a species, because it leaves room for more children + more generations (for a given set of resources), which means more opportunity for improvements to evolutionary fitness.
edit: another commenter pointed out something I think is fairly profound. When a group of cells in your body decides to pursue immortality, it's usually cancer. And if you don't address it, it kills you, and them too. Science theoretically has a way to grant our individual cells immortality without causing cancer, but it'd have to be orchestrated carefully.
You are missing the point. Op claimed that the continuation of adding new life and letting other life die out was important. I am questioning that argument not evolution. Why should i care about the continuation of life for anyone but me.
