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.
DNA testing in a citizen science project like the Q-M242 Haplogroup project must be both progressive and pragmatic. Testing is progressive when it uses new technologies like BIG Y and advanced SNP packs to discover and explore new branches. It is pragmatic when it recognizes that all cannot afford the price of such tests and finds other options.
