I wonder why this clade is never talked about. M73 is after all only one of two major lines stemming from P297, the other one being the line leading to M269. Klyosov dates M73 to c. 6000BC and dates the common P297 ancestor of it and M269 at 8000BC. So, these are siblings who are FAR closer related to each other than either is with V88. So for me, understanding the ancestors of M269 during the Neolithic is probably best achieved by looking tangentially at M73. As M269 didnt arise until 2000 years later than M73 as a clade there is not really much choice but to used M73 as a proxy for all P297 between 6000 and 4000BC. There just doesnt seem to be much P297*. IN general we should really be trying to understand M73 more than V88 if we want to understand the line leading to M269. Basically consider the brother rather than the cousin.
