Well worth the time reading, for anyone unacquainted with ancient (3,000 B.C.) S.American societies.

5. I read about Caral some years ago but

in less detail than now available.

Seems, from one old article that I read, the stone buildings there influenced architecture in later cultures of America.

The similarities in shape between the Caral pyramids and much later ones in Mesoamerican civilizations suggests to me a long-lasting cultural influence beyond the Caral region. Was there contact between Peru and Mesoamerica? Or, is the Amazon region and river the common denominator? The people of Caral knew abiut Amazonian animals. Did the founders of the Caral culture originate there or only travel there for trade or exploration of the Amazon River basin?

The Amazon rainforest climate is similar to regions of Central America, providing a possible common denominator connection between Peru and Mesoamerica.

So maybe the Amazon Basin or the Caral region of Peru were catalysts for later civilizations in the Americas. But, if so, any connection did not extend to the development of writing and the complex mathematics and astronomy that.existed later in Mesoamerica. The civilizations of Peru did not have writing.
