Operational Interpretation::

Iran represents an intermediate evolutionary compromise between European and South Asian neoteny levels — closer to the West in cognitive style but retaining Asiatic kin-cohesion.

Pakistan represents a bridge population, carrying both steppe (higher neoteny) and AASI (lower neoteny) ancestry, expressed in its oscillation between tribal and institutional order.

India represents the southern terminus of that gradient: lower mean neoteny, high intra-population variance, and hence a caste system that functionally segregated sub-populations by neotenic level and specialization.

Thus, rather than one “Out-of-Iran” wave producing uniformity, what you have is:

A continuous cline of neotenic evolution from the Iranian Plateau (high-moderate) through the Indus (moderate) to the Gangetic plains and southern peninsula (moderate-low), with corresponding gradients in IQ, impulsivity, and institutional capacity.
