Yes, No, Maybe?

Satisfaction and Evolution are two sides of the same coin-Yes, No, Maybe?
From the day we are born we fall in line to evolve our selves-ahead of our peers, kin, kith and the virtual world. But can we quantify evolution? Is it the carnal feeling of satisfaction? If yes, then do we live to a day when we wake up to a realization of "I am satisfied"? Or do we sink to the abmyssal bed the very same day "un satisfied" only to wake up the next day to again start evolving? It is a cog wheel, the cycle of life, perhaps, or the law of karma or the theory of evolution. Probably all representations of the same confused state of mind.
Is 'moksh' eternal satisfaction with the physical, meta physical, social, spiritual, emotional state. If yes, then do those who achieve it stop evolving? If yes, then should the whole human race achieve Moksh, will we fall behind in evolution and probably be overun by some other species?
Every human being urges everyday to be satisfied, evolves himself to be satisfied and then again becomes unsatisfied. This reason why we perch right at the top of the food chain and why we survived the collosal ice ages, 'pralay', Deucalion, Utnapishtim and so on.
If we are satisfied we can't evolve - Yes, No, Maybe.
This answer to this question, however grotesque, will reveal the carnal truth of life. Let's evolve and find it!
