//////////////// human populations in the past 100,000 years have adapted to a wide array of environments, devising new cultures that match human action to a variety of landscapes.


//////////////////Cultures must be willing and able to accommodate new conditions by reshaping traditions, religious beliefs, and such technicalities as rules regarding marriage and inheritance. In ancient Polynesia, for example, only a chief’s first son inherited anything, prompting other sons to disperse and explore the ocean for more land where they could built their own fortunes. This was a cultural adaptation that fit human action to the conditions of Oceania.

///////////////Human survival to date has been a result of our species’ ability to rapidly adapt our cultural practices according to local conditions.

/////////////Dopamine was “discovered” in 1958 by Arvid Carlsson and Nils-Ake Hillarp at the National Heart Institute of Sweden. Dopamine is created in various parts of the brain and is critical in all sorts of brain functions, including thinking, moving, sleeping, mood, attention, and motivation, seeking and reward.



///////////////////dopamine causes seeking behavior. Dopamine causes us to want, desire, seek out, and search. It increases our general level of arousal and our goal-directed behavior. (From an evolutionary stand-point this is critical. The dopamine seeking system keeps us motivated to move through our world, learn, and survive


/////////////// the “wanting” (dopamine) and the “liking” (opoid) are complementary. The wanting system propels us to action and the liking system makes us feel satisfied and therefore pause our seeking
