So you say, but the post to which b_sharp was replying read like a completely nutty piece of new-age mysticism. Perhaps that wasn't your intention but it wasn't just b_s who noticed it.
I've not come across this considered-to-be-mysterious "will to live" thing before, and now it has appeared at least twice in one thread. Resources are limited, organisms which struggle for existence will tend to displace those that don't struggle. All modern living things are descended from a line of millions of successful reproducers in a world where there will never be enough resources for most organisms to manage that. Call it the evolutionary tautology if you will (survival of the fittest, where the fittest are those who survive). Why is that presented as some kind of metaphysical mystery?
