Not sure I follow.
When we look at a person, the very geographical location and manner of birth defines who that person will be for the rest of their life.
For example:
Consider a child being born into a white Catholic family. From that point onwards, (s)he'll be given a name that will define it for the rest of their lives.
The child will be raised with certain values, political views, religious views, cultural views and so on. Based on their family, their surroundings, exposure to alternate views. And social interaction or otherwise. => Compounding of experiences.
While basic survival is practically inate in all organisms, the above described is entirely dependent on external stimuli. But has a very significant and profound impact on how you will live your life in relation to others. Basically, you will view the world along certain lines, you will act along certain norms and values and so on. But these are not things you came up with yourself.
Really, when we look at one single person, we're actually looking at a fragment of an organism. Humankind as a whole acts along the same lines, which is what is required to succeed in prolonging your 'life'. However, noone really acts outside of the 'norm', ofcourse there are outliers such as nutcases or cultures diverging significantly from the norm. But these are bound to be eradicated one way or another.
We are conditioned from start to finish to act and think in certain ways. To 'fit in' sort of say.
