3 million years ago, when we were "leaving the trees", the time of Lucy, we needed much more cooperative behavior to survive. It is shown in the fossil record by the rapid expansion of the mind. We still had instincts for the more common behavior of blind "red of tooth and claw" competition and we have both today, as you can find in yourself, but the balance was shifting to cooperation.

About 70,000 years ago, humans made an evolutionary step. Our brains re-organized some, the parietal lobe developed more. We became much more efficient and our tools, art, etc. showed drastic development. Our balance between cooperation and competition moved back towards competition. We started a killing spree of everything, including other humans. This peaked about the time of Rome. It was bad. There was so much warfare that two philosophies developed to teach how to cope with the horrors of war and the brutal life of the time, Stoicism and Buddhism, both of which taught how to protect one's mind. There was though one philosophy that taught how to avoid and end wars, as well as form the communities needed for civilization. It may even have been updated Zoroastrianism. His teachings was just the right software to match our mental hardware (instincts) for cooperation. If humanity can hold onto civilization and reach our potentials to become far more than animals, hopefully when the names of Odin, Zeus and Apollo are forgotten, the name of the great philosopher that taught us how to make and preserve civilization will be remembered. That is Jesus that taught us to love one another and forgive.

Pretty much everyone has figured out that cooperation is far more profitable than warfare. The Palestinians need to get with the program instead of following their instinct for blind competition.
