Dear Adejoke,

We humans are all genetically very, very similar. The variations found within an ethnic group are large compared with the differences between the means of various ethnic groups. Most humans have genetic components from many, many ethnic groups - we are a mixture. (See National Geographic's Genome Project.)

The differences in values and behaviors are principally due to differences in culture.

No.

Clarification: I prefer to use the term "ethnicity" to "race" since the latter's history has been used as if it described a distinct species of homo sapiens sapiens, and as such it is a fallacy; as a social construct race is very real; and there are ethnic variations, e.g., African-Americans have higher rates of sickle cell anemia than other ethnic groups.

Thank you sir, for the answer and clarification on race/ethniity (duly noted).We are actually curious to know why behavioural responses to life changing events vary among ethnicities; are they modulated by nature or nuture. If by nature what variations (neurotransmitter/receptors) may account for this.

Thanks Antonio Lucero, would check the National Human  genome project.

Dear Adejoke,

please take into account age as a factor that increases differences, in between nature & nurture: see alleged file

best regards, Mauro

Thanks Mauro,

May I recommend the following article to anyone thinking about heredity-environment questions. In my view it is one of the best two or three articles on the topic written in the 20th Century. And, sadly, one that has not registered in the cognitive repertoire of many many people who still dichotomize the two and still think it is meaningful to ask "which one?".

Thank you sir

unfortunately I couldn't download the paper highlighted by Justin Joffe, as it is not free access

@Mauro, I would send a message containing the  PDF
