Q-M242 is the parent to all other Q branches. Its parent is P-M45. YFull dates show that Q-M242 is between 34,000 and 29,800 years old (95% CI). This is a much older date than in older published studies, and perhaps helps explain the great geographic spread of the branches under it.
I am continuing from my previous post about updating the Native American Q-M3 branch of the paternal (Y-DNA) Tree. The team has been busy verifying branches and removing those that are not suitable for inclusion on a stable tree. As outlined before, we are excluding the use of Y-SNPs that are recurrent and branches that are defined only by recurrent Y-SNPs. The new Q-M3 Draft Tree is below.
