Basically, changes take place and life has to adapt to keep on living. The ones who can develop features that are advantageous to their subsistence, live.
This is how Charles Darwin emphasized the concept of survival of the fittest. The weak shall die and the strong shall live. Being competitive helps you stay in a very cruel world and animals in order to live had to adapt to it's environment no matter what. I cannot stop myself from associating animal behavior from people. I guess we are just the same. We adjust to different types of environment no matter how stressful and difficult it is just for us to survive.
Apt feedback buddy. that's a cool way to look at it, as far as civilization is concerned. for one, competition makes sure we aren't resting on our oars and makes for questions leading to better techs and methods for survival.
Thanks for quipping.
