The portion of evolution most people focus on is based upon the physical property of entities. From how we, humans, and other life forms started from one material stage and end up at another material stage. However, at our presents stage, I assume that we will not evolve physically no longer, however what will evolve is our knowledge and understanding of our vast community the universe. This evolution by no means will be simple, for we are a race that still harbors racism, sexism, and classism, which in my opinion still proves we are a primitive life form. Now, not all of us are these things, but a very large portion of us are still prisoners of these isms. Like in physical evolution, the portion no longer needed dies off. I know killing those who are prisoners to these isms and other isms, which hinder the portion of humanity that has evolved beyond these isms is not realistic what so ever, nor is acceptable in my opinion. However for us to continue in our mental and metaphysical evolution we must wait for these lesser primitive life forms of human knowledge and understanding to naturally die off, and not by mutilating ourselves, like those in the past has tried to do in ignorance by genocide or other means, because let’s face it, I could be wrong!!!
It seems that humanity shares just about everything we have down to our organs. Humanity knowingly and unknowingly shares ourselves and belongings throughout our entire existence. It’s very convenient for us to think that we choose what we share, but the truth is that the governing force/nature of the universe forces us to share. Some even have to share their spouses or romantic partners willingly and unwillingly, mostly unwillingly. Once we evolve in our understanding that we are sharers and that sharing is not the nice thing to do, but what we must do, then humanity will become a more peaceful and coherent society. Remember you share the air your breathing right now with every living creature on this planet!
Without the civilizations of old, we would not be at our glorious present state. Look not at the past as lesser, but contributors. Their experiences, knowledge, and wisdom is what we have built upon to accomplish the great feats up until our present age. Those after us will do the same, and so on.
