Ydna tree with CF as the y-dna Adam (actually Noah) and the African haplogroups of A and B as descendants of CF rather than ancestral
There is no constant rate of mutations between the ydna haplogroups. Ydna mutation rates are influenced by environmental, cataclysmic (radiation) and geographical factors. It is also influenced by the dna of the woman that the Patriarchs marry into. The differences between the descendants of Ham, Shem and Japheth are influenced by their wives genes which effects the new y-dna mutations that occur in their offspring.
We also see this with the different y-dna mutations found in the offspring of the three wives/ concubines of Abraham. Some of the differences between IJ and K are due to the women and also that Ishmael was born before the cataclysmic events that destroyed Sodom and Gomorrah. Isaac and the sons of Keturah were born after these events which effected their ydna differently to Ishmael and his sons. This seems to be partially confirmed in recent studies in both humans and mice where trauma is found to be inherited and changes certain parts of the y-dna.
It is clear that the mt-dna matriarch's of N, M and L3 are the main matriarchal lineages of the Shemites (C,F), Japhethites (DE) and Hamites (BT). It is a possibility that these three Matriarch's could represent the three wives of Noah's sons. However it is more likely that they represent three matriarchal lineages of the white skinned, blonde haired daughters of Shem's wife Lebab or Labana (meaning heart and white). L3 or Luba (a "daughter" of Lebab) married a black grandson of Ham and they became the ancestors of A and B ydna. N or Neshema or Milka (Queen) married to Cainan the King of Eridu from within the clan of Shem and they became the ancestors of F ydna. M or Medea married Japheth's son Javan and they became the ancestors of E ydna. In fact Milka, Medea and Luba are the great-granddaughters of Lebab (Lebana) the wife of Shem. It would seem that the black skinned and black haired Nahalites or Denisovans (daughters of Ham's wife Nahal) married firstly among the Shemites of C ydna (Clan of Arpachshad-Charran). The red-bronze-yellow skinned, red haired Adanites or Neanderthal (the daughters of Japheth's wife Adan) firstly married among the Japhethites of D ydna (Clan of Tubal-Dsemschid (Jamshid)).
It would seem that C ydna descends from Arpachshad's grandson Charran (son of Cainan) and that F ydna descends Shelah and Heber. The Charranites of C ydna divided into two main groups the black-skinned C1Andaites and the bronze-skinned C2 Mongaites. Thus the clan of Arpachshad is more correctly called the Clan of the Charranites. Of course Arpachshad and his brothers belong to the Shemite CF ydna.They should not confused with the Haranites of H ydna descended from Abraham's brother Haran and his son Lot. These Haranites are divided into the mostly dark-skinned H1, H3 Haranites (Moabites) and the mostly white-skinned H2 Haranites (Ammonites).
Many researchers and medieval writers made the mistake of identifying European ancestors with the sons of Japheth due to the area of Europe once being settled by the Japhethites before the Ice Age and being named for them. After the Ice Age new populations gradually moved into Europe and became associated with the Japhethic names. The only Japhethite population in Europe today are some of the Javanites of E ydna haplogroup who returned to Europe some time after the Ice Age.
Note: It is rather disappointing that those who believe man is only 6,000 years old and that the world was restarted by Noah's family have not come forward with more theories on how to read the genetic evidence but have left this mainly to those of an evolutionary mindset. In my rather sporadic and haphazard manner I have tried to bring up some ideas on how to do this on this blog but I am praying that we might get new Velikovsky-like genetic historian from among the younger generations to come forth and take us forward in our understanding of our genetic history and the movements of tribes and peoples.
