Bonnie and Matthew got to know each other as a result of our first paper on A00, "An African American Paternal Lineage Adds an Extremely Ancient Root to the Human Y Chromosome Phylogenetic Tree," of which we were co-authors.
Matthew, a doctoral candidate in History, was the collector of the original Mbo DNA samples -- among many others -- from Cameroon, which testing found to belong to the same extraordinary branch as the Y chromosome of the Perry family in the U.S.
Bonnie, a long-time volunteer project administrator, had organized the testing of the members of the A Haplogroup Project, including the Perrys, leading to the discovery of A00 as well as several other early branches of the tree.
We could see that the mere discovery of A00's existence was only the first step; so much more can be learned. We decided to work together to collect DNA samples from key ethnic groups across Cameroon, which could give a far more complete picture of A00's distribution, frequency, and diversity.
