The previous archaeological assumptions seem to present a constricted view.Only because the characteristic pattern has been found in the vicinity areas previouslyThe observance of a certain phenomenon in an area does not mean it is restricted to that area. Furthermore, in ancient times people used to trade their goods in exchange of food. Also , and fishing was anrather important food source; hence,there must have been significantthe interaction between these across-the- river villages must be frequent .
In order to properly analyse the argument, we must first and foremost need to understand the frequency and nature of the interaction between the two communities. The absence of 'Palean' boats sodoes not provide sufficient evidence that there was no interaction between the people of Palea and of Lithos. The ancient boats mightmay have withered over time, or sunk or . Also, the Paleans might have been usingused boats other than those we identify as 'Palean' boats. Furthermore, there may have been more Lithosians travelling to Palea than otherwisevice vera . Thus the travel might have been more frequent than previously thought.
The woven baskets with the Palean patterns may still be of Palean origin and were perhaps traded with people of other villages including Lithos. Again, the boat travel through boatscancould have beenbe possible due to previously explained reasons. Futhermore, there is a chance that via fishing, the two villages might have interacted more hence increasing the exchange of goods.
Another possible argument as thatAdditionally, although the travelling across the river may not have been easily achievablemight be as rare as thought, the transfer of basket manufacturing skills and techniquesismay still have been possible. The Travelers mightcould have learnedadapted the specific patterns and integrated them into their baskets,evolved thespreading basket weaving furthermethods . The fact may be explained wellThis could be proven if such an evolution of design and patterns is seen in the baskets and other woven items in the region .
Since Archaeology is a science on unearthing the past; yet, manyhowever several truths might still remain hidden. Hence We should remain open to the possibilityies that certain evidencesmay be flawed, these may becomehave loopholes which might be more visible if contradictory evidences appears . In this case, Palean baskets were not Palean because they were found near the village but because they were yet not found anywhere far away.
The piece lacks clarity and structure. I have attempted to rectify the grammatical errors, of which there were a significant amount.
I suggest that to extend the piece you elaborate more on the already mentioned aspects, for example: saying how the remains of riverboats may have disintegrated over time based on environmental factors, etc.
I hope this helps, should you chose to adapt my alterations. Good luck!
