Prince,
I am no expert. This is part of the article:

A large proportion (65%) of the African-European mtDNAs investigated could be attributed to modern and well-documented demographic routes that existed during the Romanization period, the Arab conquest, and the trans-Atlantic slave trade. However, there is strong evidence pointing to the fact that the remaining 35% of the African L-European mtDNAs stand as modern witnesses of sporadic population movements occurring between the two continents that might have begun as early as 11,000 yr ago (Fig. 5).
These contacts were not only restricted to North Africa, but connected Sub- Saharan regions to Europe directly via coastal routes or first crossing North African territories toward the Mediterranean Sea. 10,000 Years before Slavery, Arab Conquest or Roman period Outside of Africa.
Attention should also be brought to the L2a1 clads above who also have an Indigenous North American Origin i.e.. (Indigenous Native American) (USA Origins), although they carry an African Haplogroup. Some of these Haplogroups are only found in Europe or the Americas, and Not in Africa. These groups may also produce a Mulatto, Native American, or European Pheno-type (features such as Straight or Curly hair types and multitude of different complexions). Some of these particular Haplotypes has African and American Origins, but the Haplogroup is 100% African. (i.e.. North African, East African, South African, West African). This group may also share genetic ancestry with other Indigenous Americans, as well as the Asiatic-African Moors of America.
A single L2d1 sequence from the Yemeni sample shares the haplotype that has so far been observed in Sudan and in southeastern Africa
Ethiopian L2b sequences form a subset of a predominantly West African clade, distinguished from West African lineages by a transition @ np“16145″."
