Coastal villages, which were likely numerous & permanent, & lived off of abundant fish & dense populations of littoral animals, have been largely lost to archaeology due to global warming & sea level rise at the end of the last glaciation.
The abundance of littoral food sources probably gave coastal peoples more motivation than inlanders to stay longer & store more food, so they may have been the original sources of this adaptation cluster (dogs, vermin, pottery). Archaeologists only have access to inland sites.
Long-term coastal settlements may have resembled those much later documented by travelers & ethnologists, for example the Nivkh https://en.wikipedia.org/wiki/Nivkh_people … the Kwakwakaʼwakw https://en.wikipedia.org/wiki/Kwakwaka%CA%BCwakw … and the Yurok https://unenumerated.blogspot.com/2017/02/conflict-and-collectibles-among-yurok_87.html …
One must be cautious about the documented observations, however, since, especially in the case of the Kwakwakaʼwakw, they were often made after their cultures had been severely disrupted by European contact.
ht to the polymath Tim May for pointing out to me the likely importance of coastal villages as technological leaders during the millennia leading up to the dawn of agriculture.
Obviously a clear line can be drawn between this ancient cluster (dogs, vermin, pottery) and the equivalent modern cluster (public blockchains, nation states, cryptography).
