Life has become increasingly more sophisticated as time goes on. From single celled organisms to the symbiotic relationship between multiple cells comprising the human body.
This has only been possible through a constant battle or thousands of generations and billions of species, fighting for dominance.
We are at the bring of the limit of what our earth can support. Natural selection will still continue on earth, but as we become smarter and more resilient, life will begin to expand to other planets.
This will allow for an interesting phenomenon. A collective set of cells evolve together through the human body, with billions of humans helping the process along at any given time.
Once we start expanding outside our own planet, and outside our own solar system, we are going to start observing societies acting collectively as one single unit. With enough space available, societies will be acting as a single organism, and natural selection will start choosing which societies are best fit for the universe.
The point of life is to see what is best suited for the trials and tribulations in the obstacle course that is our universe. We are already trending from single-celled organism, to multi-celled organisms, to symbiotic organisms, and now onto societies in which the agents (citizens) are starting to act in unison, under the direction of a centralized (nervous) system (the government).
As our world becomes more interconnected, through the advent of telecommunication and air travel, we are already starting to fight amongst ourselves at an increasing rate. That is simply natural selection starting to work its way onto larger systems, in order to determine which societies are best suited for the environment.
Our individuality and free will will always exist, but eventually societies which better act in unison may beat out (evolutionarily) societies which allow for too much creative thought.
Or, on the other hand, societies which act as a template for capitalistic free thought in a decentralized fashion may turn out to be better suited to the universe through quicker adaptation to unknowns, and may be better suited for the universe than a centrally controlled society.
Time will tell. And by time, I mean the millions of years which define the evolutionary timescale.
