interesting. I don't buy that it is transmitted genetically though, what other mechanisms do you think are at play?
both genetics and acquired, learned behaviors are at play, nature AND nurture, nothing too complicated to figure. Fact is we blindly reproduce our direct ancestors past thinking we have a clue what "we" are doing when we re just repeating strategies of survival over and over again that have been used by people before us. Until we find God , consult a shrink , etc and we substitute our subconscious values with new religious,spiritual, philosophical values. And the shit repeats itself over and over again generation after generation.
BTW, when a flying bird detects a pond, a place filled with trees full of fruits etc, it is recorded in its brain, and ...sperm, then it reproduces, then dies, and in the next generation, his offspring, the data, informations are recorded into the offspring genes and it "knows" where are these places without ever seeing them with its own eyes. Every single life form is just a bunch of recorded data, strategies of survival. We are no different.
