Since I am no genetics specialist, I did not feel legitimate about predicting human beings' evolution from a physical point of view. I preferred to imagine it metaphorically.
When one observes current society, human greed is extremely obvious. Money leads almost everything. What let me bitter, is the fact this greed is often totally useless: while some money can be obviously useful to live comfortably, accumulating it just to be able to write more "zeros" on a bank account makes not much sense to me. I feel like there's no precise goal to that, except the thrill to possess more and more, to keep stacking things blindly, even if it reaches the point where it becomes destructive. I look at such behavior like a severe addiction.
This is such feeling I wanted to share through my image. I chose to depict a dark future, where the new leading animal (obviously evolved from human beings) keeps working towards a goal, without really knowing why. This lack of conscience is symbolized by the hole in the middle of their chests, while they keep feeding the big fat creature that they worship.
