humans, unlike any other species has a continued drive for information, yes other animals use tools as an aid - but we as a species not only use crude tool's but we perfect it and improve on it over and over - this is what sets us apart from other animals - where as they stop at rocks and move around to find food - once upon a time we did this - but planting, and replanting over and over atchived a much bigger yeild, like wheat for example - you could at one point have lost a cow in wheat - but now, to save on waste and increase yeild - it is no higher then 2ft. thats because of sucessive breeding or cross polination of wheat, has gradually bread the size down- therefor making less waste.
this amongst other things sets us apart.
we dont really have the desire to have a community sence anymore - we just live close to our jobs, instead of all together for protection - this is due to the fact that, actually weve eliminated all threats - and what i mean by that is human nature to problem solve, like bears - weve killed them all to a manageable population, wolfs - same thing, anything that has posed a threat has been wiped out to provide safety.
people say were greedy, were not, we are just stripping the world of resorce like weve always done, exploiting every situation and area' finding a food sorce all the time.
like the evolution of wepons. this i belive will be the one area, which will prove the downfall of humanity- because of our outright desire to crush anything that pose's a threat.
