Y-chromosome DNA Haplogroups are based on SNPs, Single Nucleotide Polymorphisms, that occur in the non recombining region of the Y-chromosome. Haplogroup Q is one of two clades within the mega-Haplogroup P. It is defined by the SNP M242. This mutation is believed to have occurred 15,000 - 25,000 years ago. Q is found in Asia, the Americas, Europe, and the Middle East.
Q-M242, like its P lineage parent, was almost surely born in South Asia. Some lineages spread to East Asia from there. It is not clear though if they traveled directly north, through the Himalaya mountains, or along the southern coastline. It is entirely possible that all paths were taken at different points in Q's history. We also know that many branches repeatedly turned west to what are now considered Europe and the Middle East. Some of the lines that traveled to East Asia crossed over the temporary land bridge into the Americas. From recent publications, we know that this too may have been a process of multiple migrations. Our Q ancestors took many migrations and faced life changing challenges. Similarly, we as leaders and members of this project seek together to take a journey of discovery that will change our thinking about who we are and what we understand of our past.
