Re: Lagoon lodges by 'Beach-pocket beaver-otter-apes'
- The remaining question therefore, is, what caused these small family lodge units to make small communities of separate nearby dwellings, (something beavers avoid)?
An answer might be, a nice lagoon with a few small freshwater sources, trickling brooks or so, that could be easily dammed during the dry months, then washed out during the rainy season, allowing anadromous fish species (eels, salmon) transit and entrapment, and croc and shark prevention. Having lodges on both sides of the stream would be advantageous for both observation and repair. Lodges along the seashore would be slightly dispersed, to prevent overlap of harvesting, a brief walk along the flat wet sand to get some freshwater in a seashell would be a daily exercise and fits with beachcombing and wading when sun is not optimal for diving. This sounds very sapient, but could have been done much earlier as well, relying on natural damming at low tide and after the storm season.

Nests change daily, reduces parasites; whereas Human ancestors salt-showered daily and sun bathed reducing parasites.)

(Today people trim them off to reduce rat nests, for easier access to nut harvesting, and for aesthetics). Some palm leaves are thorny, others not.

Stone or shell hand-axe tomahawks were used to notch hand-holds/ladder steps in palm trees for quick climbing. (Still used by traditional people in Borneo and Papua to climb stilt longhouses and tree houses, they're often made slippery to prevent snakes, rats, cats and komodos, so good balance while stepping up is required, something which humans are good at.)
> A beach lodge, warmer in winter, cooler in summer, but washed away in rainy season, so rebuilt annually with fresh reeds/fronds etc. Separate toilet pits not too far away, repeatedly covered with sprays of dry sand, trenches like garden rows, later after rainy season digested fruit seeds sprout there, above the salt sea level, little fertile fruit orchards amongst the sterile sands, enriched by fish guts (recall AmerIndian method of planting corn with minnows) and midden wastes, with few weeds or insect pests, tiny oases surrounded by desert-like sands of seashore beaches just above the highest high-tideline, roots sustained by the organic manure until reaching the brackish-fresh water table below, surviving the hostile parching sun, eventually providing buds, leaves, flowers and fruits to the next generation on the shoreline.
