Into Human 3, 2008) — The Y chromosome retains a remarkable
record of human ancestry, since it is passed directly from
father to son. In an article published in Genome Research
scientists have utilized recently described genetic variations
on the part of the Y chromosome that does not undergo
recombination to significantly update and refine the Y
chromosome haplogroup tree. In 2002, the Y Chromosome Consortium
(YCC) constructed a tree of 153 haplogroups based upon 243
unique genetic markers. In this report, researchers led by Dr.
Michael Hammer of the University of Arizona recognized the need
to revisit the Y chromosome haplogroup tree and incorporate the
latest data. "The YCC effort in 2002 was a landmark in
