Natural Selection - Inspired by Darwin

Nature always interests me because it is full of unknown principles and concepts.
I was wondering one beautiful Spring morning on the way to work why there are wars on earth among human beings. Is it part of the big plan of evolution? If so, what are we evolving into? In the Jurassic period Dinosaurs were all over the planet and were the most powerful and most evolved of the beasts that existed then. But soon after they became their own enemy and started killing each other and ofcourse nature played its part too leading to the extinction of it.
Coming back to us, are we in the pinnacle of our evolution or is there more? I believe there is more. Nowadays kids are so intelligent and that is because we no longer need physiological evolution but brain evolution. The environment around us is polluted and more diseases are coming up everyday that is because the Bacteria and Virus are evolving and becoming resistant to our drugs. So now we need to evolve into better brained beings to take up this challenge and to merely survive, otherwise a simple outbreak can tear us down and make us extinct, in addition to our own wars. This is natural instinct built in our genes. Isn't that amazing! I wont be surprised if Einstein's become common among our species. Infact it might even become one of our traits.
What triggered these thoughts? Well, I was reading the "Origin of Species" by Darwin - An eye opener for the intelligent species known till today in this universe, Man.
