Scientists reshape Y chromosome haplogroup tree gaining new insights into human ancestry

The Y chromosome retains a remarkable record of human ancestry, since it is passed directly from father to son. In an article published online today 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. The print version of this work will appear in the May issue of Genome Research, accompanied by a special poster of the new tree.
