Domestication of dogs & the dawn of pottery probably increased the time clans could remain in one place, perhaps from weeks to months & even, by sea shores, in permanent villages, leading to long-term food storage, which rats & other vermin could take advantage of.

This was during the last glaciation of the ice ages, so the climate likely would have resembled today's northeast Asia more than today's southeat Asia.

All of today's domestic dogs descend from a common wolf ancestor that lived about 30,000 BP in southeast Asia. It was probably domesticated in that region around that time or a few millenia later: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4816135/pdf/cr2015147a.pdf …

The alarm system of barking dogs helped protect people in a long-term camp or village along with the food stored in that settlement. Dogs could provide an emergency food source & may have facilitated the movement of stored food by pulling sleds.

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.
