19. Humans are divided into numerous distinct genetic groups called haplogroups.

several of which are dominated by dark skinned peoples.

The L type consists of nearly all Africans.

The M type consists of:

M1- Ethiopian, Somali and Indian populations. Likely due to much gene flow between the Horn of Africa and the Arabian Peninsula (Saudi Arabia, Yemen, Oman), separated only by a narrow strait between the Red Sea and the Gulf of Aden.

CZ- Many Siberians; branch C- Some Amerindian; branch Z- Many Saami, some Korean, some North Chinese, some Central Asian populations.

D- Some Amerindians, many Siberians and northern East Asians

E- Malay, Borneo, Philippines, Taiwan aborigines, Papua New Guinea

G- Many Northeast Siberians, northern East Asians, and Central Asians

Q- Melanesian, Polynesian, New Guinean populations

The N type consists of:

A- Found in some Amerindians, Japanese, and Koreans

I- 10% frequency in Northern, Eastern Europe

S- Some Australian aborigines

W- Some Eastern Europeans, South Asians, and southern East Asians

X- Some Amerindians, Southern Siberians, Southwest Asians, and Southern Europeans

Y- Most Nivkhs and many Ainus; 1% in Southern Siberia

So why the concept of race may not apply, skin color certainly does when determining genetic susceptibility to certain diseases - skin color is a prime indicator of what haplogroup you belong to.
