Original sentence: Its goal is to study the ancestry of lines commonly considered to be Melungeon.More recently, the independent researcher Jack Goins has acted as coordinator of the Melungeon DNA Project, which started in 2005.So far, Y-chromosomal DNA testing of male subjects with the Melungeon surnames Collins, Gibson, Goins, Bunch, Bowlin(g), Denham, Mullins, Hopkins, Perkins, Williams, Minor and Moore, has revealed evidence of a majority of European and sub-Saharan African ancestry: Y haplogroups R1b, R1a, I1,   and E1b1a, respectively.Taken as a whole, such findings appear to verify the nineteenth-century designation of Melungeon ancestors as "mulattos", that is, descendants of white Europeans and Africans.This finding is consistent with the findings of research by Paul Heinegg and Dr.Virginia DeMarce
Edited sentence: More recently, Jack Goins has acted as coordinator of the Melungeon DNA Project, with the goal of studying the ancestry of hypothesized Melungeon lines.So far, Y-chromosomal DNA testing of male subjects with the Melungeon surnames Collins, Gibson, Goins, Bunch, Bowlin(g), Denham, Mullins, Hopkins, Perkins, Williams, Minor and Moore has revealed evidence of a majority of European and sub-Saharan African ancestry: Y haplogroups R1b, R1a, I1,   and E1b1a, respectively.Taken as a whole, such findings appear to verify the early designation of Melungeon ancestors as "mulattos", that is, descendants of white Europeans and Africans.This finding is consistent with the documentation and research by Paul Heinegg and Dr.Virginia DeMarce; and why not since these three researchers are such close friends
