The continuation of species. A flawed concept?

Recently, it just occurred to me that the lives of most living creatures is ultimately somewhat futile. Why do animals have these special characteristics in order for them to survive? Simply to ensure the continuation of their species. But then, once one thinks about it, why should they continue their species? What is the ultimate goal of this… theory?

For the animals to finally end up filling every nook and cranny of this planet? And even then, so what? Animals can’t live once they triumph over every other species. They’d just end up eating everything and destroying the environment before dying out. We need the many interactions present in nature in order for everyone to survive.

So the only answer to this is that the continuation of species is just that. To allow your species to continue. Sure, some will die (partly because of other species eating them in order to ensure the survival of their own species). But others will live. But just enough to ensure that you just crawl on through the ages.

Then this leads on to the next issue. So why even bother? Why even bother having all these species if they can’t even take over the world? What’s the point then for these species to even exist? Can you say that there doesn’t even have to be a point? Just that it is?

Of course, once you apply this to human beings, the situation becomes much more complex, for we are capable of thinking and rationalising these existentialist thoughts. But then again, does that even make a difference?
