Haplogroup Q-M3 was previously known as Haplogroup Q3(currently Q-M3 is in Q1a2-M346). In 1996 the research group at Stanford University headed by Dr. Peter Underhill first discovered the SNP that was to become known as M3. At the time, it was called DYS191. Later studies completed the genetic bridge by determining that Q-M3 was related to Q-M242-bearing populations who traveled through Central Asia to East Asia.
Origin and Distribution
Haplogroup Q-M3 is one of the Y-Chromosome haplogroups linked to the indigenous peoples of the Americas (over 90% of indigenous people in Meso & South America). Today, such lineages also include other Q-M242 branches (Q-M346, Q-L54, Q-P89.1, Q-NWT01, and Q-Z780), haplogroup C-M130 branches (C-M217 and C-P39), and R-M207, which are almost exclusively found in the North America. Haplogroup Q-M3 is defined by the presence of the (M3) single-nucleotide polymorphism (SNP). Q-M3 occurred on the Q-L54 lineage roughly 10-15 thousand years ago as the migration into the Americas was underway. There is some debate as to on which side of the Bering Strait this mutation occurred, but it definitely happened in the ancestors of the indigenous peoples of the Americas.
The Americas
Populations carrying Q-M3 are widespread throughout the Americas. Since the discovery of Q-M3, several subclades of Q-M3 bearing populations have been discovered in the Americas as well. An example is in South America where some populations have a high prevalence of SNP M19 which defines subclade Q-M19. M19 has been detected in 59% of Amazonian Ticuna men and in 10% of Wayuu men. Subclades Q-M19 and Q-M199 appear to be unique to South American populations and suggests that population isolation and perhaps even the establishment of tribes began soon after migration into the Americas.
Asia
Q-M3 is present in some Siberian populations in Asia. It is unclear whether these are remnants of the founding lineage or evidence of back-migrations from Beringia to East Asia.
Europe
The Q-M3 lineage has not been detected in the European population.
Subclade Distribution
