Original sentence: 2004 argue that the H71 haplogroup and North African Y-chromosomal diversity indicate a Neolithic-era "demic diffusion of Afro-Asiatic-speaking pastoralists from the Middle East", while Nebel et al.According to University of Chicago's JournalsBosch et al.Arredi et al.In general, genetic evidence appears to indicate that most Berbers (whether they consider themselves Berber or Arab) are predominantly of Berber Afro-Asiatic origin, and that populations ancestral to the Berbers have been in the area since the Upper Paleolithic era.Significant proportions of both the Berber and Arabized Berber gene pools derive from more recent migration of various groups who have left their genetic footprints in the region.The interpretation of the second most frequent "Neolithic" haplotype is debatable: Y chromosomes are passed exclusively through the paternal line
Edited sentence: 2000 and Bosch et al.2001, argue that the H71 haplogroup and North African Y-chromosomal diversity indicate a Neolithic-era "demic diffusion of Afro-Asiatic-speaking pastoralists from the Middle East", while Nebel et al.2004, like Semino et al.According to University of Chicago's Journals, Bosch et al.In general, genetic evidence appears to indicate that most north Africans (whether they consider themselves Berber or Arab) are predominantly of Berber Afro-Asiatic origin, and that populations ancestral to the Berbers have been in the area since the Upper Paleolithic era.Merriam-Webster defines "Berber" as "a branch" of the "Afro-Asiatic family".Significant proportions of both the Berber and Arabized Berber gene pools derive from more recent migration of various Africans, and all other intruders who have left their genetic footprints in the region.The interpretation of the second most frequent "Neolithic" haplotype is debated:Arredi et al.Y chromosomes are passed exclusively through the paternal line
