All of the above features I might mention are quite common in the majority of primates from great apes to tree top dwelling monky bands.

There are a number of unconscious desicions taking place within the context of the dominance heirarchy that profoundly influence one's reactions and attractions...so the "that" is for the most part the thing motivating such responces.

Wanting something else, something new, seeking the next thing, are strong base evolutionary inborn instinctual desires of all animals...humans included. We wouldnt ever explore or seek out knowledge of our suroundings beyond what lay directly before us if we didnt do this first. Its all part of our normally functioning brain chemistry. Its not in the slightest way wierd once one accepts who and what is for who and what one is.

Of course one reacts to protect or keep what one has obtained dominion over. Again its part of the hardwireing of our brains. Watch children play with one another when they are not aware that they are being observed and you will see the them acting in exactly such a fashion, and if they come to blows etc with each other and are reprimanded they often give as their excuse for their actions a befuddled look and say I dont know, or a its mine she cant play with it etc.

Without such drive inheriently woven within our tapestry in our phisiology we wouldnt be capable of surviving successfully enough to enjoy any of the other comforts you mention.
