AI Thread Summary
The discussion centers on the observation of behavioral and physical similarities among family members after a long separation. Key points include the recognition of shared health beliefs and personality traits between the speaker and their mother and first cousin. Notably, a second cousin exhibits the same childhood sleeping patterns as the speaker did at age 11, while another second cousin shares similar physical features and personality traits. The conversation explores the genetic basis for these similarities, suggesting that behaviors and personality traits are largely influenced by genetics, particularly through genes that regulate emotional control and hormonal fluctuations. It is noted that personality development occurs early in life, implying that environmental factors shaping behavior were established before the speaker's separation from their family. The idea of behavior groups within families is introduced, indicating that certain family members may belong to distinct behavioral classifications. The discussion also raises the question of whether genetic factors could influence hormonal fluctuations that affect sleep patterns.

I was separated from my extended family for many years. When I returned, I noticed similarities among the members' behavior.

My mother and first cousin possesses similar beliefs in health, and a general similarity in personality.

My second cousin possesses the same sleeping patterns that I possessed at age 11.

Another second cousin possesses similar physical features and an extremely similar personality to me.

How are behaviors passed to human spawns?

It proabably has to do with the genes regulating emotional control centers.

As far as sleep patterns.. those have a a lot to do with daily fluctuations in hormone patterns.

You behaviors are similar.. because all those factors controlling behavior.. are at their root genetically controlled. Also keep in mind that our personalities are pretty much developed by ages 3-5. Soooo.. the environmental factors making you who you are. were established well before you were separated from your family.
 
Though, with the case of my "another second cousin", we never interacted. I have been separated from my extended family since I was 5 or 6, and I am 19 now. The cousin is 7 or 8. We differ greatly from the family also.

What seems to exist is a series of behavior groups. Specific humans within the family may be classified under one group. My cousin and myself may be classified in a rare group.

As far as sleep patterns.. those have a a lot to do with daily fluctuations in hormone patterns.

If corruption exists in the fluctuation of hormone patterns, could this cause be produced by genetics?

I am reading Nicholas Wade's book A Troublesome Inheritance. Please let's not make this thread a critique about the merits or demerits of the book. This thread is my attempt to understanding the evidence that Natural Selection in the human genome was recent and regional. On Page 103 of A Troublesome Inheritance, Wade writes the following: "The regional nature of selection was first made evident in a genomewide scan undertaken by Jonathan Pritchard, a population geneticist at the...
