Intelligent Beings

Intelligent life forms
What is it?
Is it really what we think or it's just a manifestation of us being superior than other beings?
May be not but how?
lets assume a scene amid plains of Africa a family of early human species is wandering without food and protection from predators such as lions and snakes and mother nature to make matters worse so to ask do they really have a chance? may be not but to analyze this hypothetical scenario with a pinch of salt and we need to know that the leader of the family will need to find a safer place for his family arguably a cave but what makes him believe that a cave will help him in this case? also what is the exact cause for a human like species to go for a stick or a stone in order to engage his enemy in the first place.
An intelligent guess will be a three dimensional movement i.e moving up and down the trees along with walking in the plains which in time will increase dexterity of the upper limbs like in case of modern day monkeys and chimps but by just moving up and down the trees a species could become modern humans is a difficult thing to comprehend when we can see many of today's primates in zoos and sanctuaries but this can be explained in a simple way that it is the first mover advantage i.e to say that those primates or human like species which were more adventurous and tried to move beyond the trees had the added advantage of  being dynamic(if we can say) in a way that these few creatures were the only ones who were regularly moving in and beyond the trees and constantly trying to negotiate flat lands(terrains) other than being where they were born.
but why?
Without being certain an argument can be made that may be these primates were outcasted by their fellow primates due to may be erratic behavior in the group or may be because they didn't simply fit in with the rest which further leads us to questions like does those who don't fit in the community or have a tendency to be sidelined or just say those who are not social superstars have a tinge for innovation and in turn a sense of disruptive evolution which ultimately leads to better race?
May be or may be not but one thing is for sure those of you who have seen the movie "Social Network" or "jobs" will tend to not disagree with me.
