Geneticists have discovered that most of mankind who lives outside Africa has the M168+ y-dna mutation descended from CF and DE ydna whereas AB found in Africa does not have this mutation and thus is M168- y-dna. The evolutionists claim that the common ancestral y-dna Adam is thus earlier than M168+ ancestor. However there are other ways of understanding the lack of M168+ in A and B haplogroups of Africa.
CF (P143) and DE are obviously the descendants of Shem and Japheth. AB which is M168- are the descendants of Ham. Was Noah M168+ or M168-? Ham is believed to be the youngest of the brothers by many scholars. It is possible that Noah was M168+ and then Ham for some reason was conceived without M168+. Or Noah may have been M168- and his descendants outside Africa received a group mutation of M168+ which the ancestors who were in Africa didn't. Or if Ham was actually the eldest son then Noah may not have had M168+ but it occurred only in his younger sons Shem and Japheth. Biblical scholars dispute whether Shem or Japheth was the elder and translate Genesis 10:21 in different ways. However this is only referring to Shem and Japheth being older. It is possible that Ham is in fact the eldest of the three brothers rather than the youngest. I personally think Shem is most likely the youngest of the three brothers.
I think it is most likely that these mutations did occur in Japheth and Shem due to some kind of environmental or radiation effect that occurred after the birth of Ham the eldest son in the days before the Flood. We know that Noah is described in the Book of Noah preserved in the Book of Enoch as very fair skinned and as white as snow. His wife and sons were also white. We know that the descendants of Ham were black and those that were whiter like Nimrod. Thus it is most likely that Ham's wife was black and that some of her sons and daughters were a mixture of black, white and brown.When her black descendants married other black descendants and moved away from other less black descendants the black race was produced. However some of these black descendants of Ham's wife Nahal intermarried with those descendants from the bronze yellow-reddish skinned, red haired Adan wife of Japheth and the blonde white skinned Lebab wife of Shem and thus there were also black Japhethites and black Shemites.
The red hair found amongst the Hebrews may have come through the Hebrew matriarch Rebecca's mother the wife of Bethuel. In ancient writings both Sarah and Rebecca are described as having milk white hair and skin. Though it is also possible that Abraham's mother Edna or Adina was red haired.The name of Edna or Adina comes originally from Adan (meaning red). Jacob's daughter Dinah may have also been a red head like her brother Judah.
The evolutionists propose above CF and DE (also called CT) a haplogroup called BT. They then propose that BT descends from a branch of A1b. However A and B are descendants of their socalled BT who is actually Noah. Noah is a direct male line descendant of Adam and this is the only y-dna from Adam that survived the worldwide Flood. However instead of A1b being the ancestor of BT it is a son or descendant. The A y-dna descended from Ham's sons Mitzrayim and Put and their sons were the first to move to Africa before the splitting of the continents. Later the Cushites of B at the time of the splitting entered Africa and then the Canaanites of B moved to Africa after their expulsion and extermination by the Israelites. However most of the Canaanite male lines died out or were exterminated and their descendants are mostly likely belong to B1 and B3 y-dna haplogroups.
We know that J1 is the haplogroup of the descendants of Mohammed and many Arabs who are descended from Ishamel the son of Abraham. So looking at the haplogroup tree we see that the ancient Hebrews descend from F and CF haplogroups. There are different opinions about what haplogroup the descendants of Isaac the half-brother of Ishmael belongs to. J1 and J2 and E found among Jews and Cohenim mostly come from the conversion of many Samaritans to Judaism in the 2nd and 1st centuries BC. Thus the so-called Cohen Model Haplogroup is in fact of Samaritan origin not that of the ancient Israelites. Both J1 and J2 are descendants of Ishmael.
Ishmael the son of Abraham was born before the cataclysmic events of the time of Sodom and Gomorroh. Abraham's other sons by Sarah and Keturah were born after these cataclysmic events and it is in them and their descendants that K-M9 mutation is found. Isaac's son Jacob and Isaac's Keturahi half-brothers descendants all had the mutation K2-M526 except Esau and his descendants didn't. It would seem that K2-M526 was a group mutation which occurred in these groups after Jacob left Palestine as did Abraham's sons by his dark skinned wife Keturah who Abraham sent eastward. Esau and his sons were born in Palestine and instead of M526 mutation they received the mutations L298 and P326 (LT).
