Hypothesis
There is a core tradition of characters ('flat-weave designs') in Iranian tribal textile traditions that changes gradually over time through descent with modification, while characters on the periphery are shared among different contemporaneous populations ('pile-weave designs').
Note
The authors suggest that 'pile-weave designs' have different rates of evolution because of the bigger influence of horizontal transmission, which was not supported by the results.
