On March 7 2013, Mendez and colleagues from Michael Hammer's group reported a most amazing discovery: an ancient Y chromosome that lies at the basal position of the Y chromosome phylogenetic tree and estimated to have emerged 338,000 years ago. The results had tremendous implications to the origin of our species and raised speculations as to the origin of the "Y chromosomal Adam." Not surprisingly, the study had no biological nor mathematical support and the findings were achieved through data manipulation as we show in this video and in our paper (The "Extremely Ancient" Chromosome that Isn't: A Forensic Bioinformatics Investigation of Albert Perry's X-degenerate Portion of the Y Chromosome, published in the European Journal of Human Genetics).
