I was not ornery Bk. Isn't your background in genetics I was honestly asking a question. Like I notice white people are better with the cold than most others and Caribbean people tend to be less hair than whites. Just wondering if their was a genetic difference. My God woman. Sip your wine and go dance for Petty I command this.
Supposedly we have wider noses to deal with hotter climates, while whites generally have more narrow ones to for warming air more effeciently in colder areas can't remember where I seen that but the genetic differences do exist in one shape or another. Some of this is due to adaptation to environment, which has been shown to take place over time in other life forms
Two links to further help explain adaptation to the environments are... Minorities and Genomics DNA, Ancestry, and Human Migration
