These two river valleys were similar, because they both had a government form in hierarchy. They both had a ruler, and they were in the monarchy system. Some of the systems were considered to be well off systems because they were able to rule without disruptions and others had systems which were not in equality with men and women.
Answer:It is fairly clear that the Mexican highlands were far too dry during the much warmer interval that prevailed from 5000 to 1500 BCE for agriculture to supply more than half of a given population’s energy needs. This was not the case along the alluvial lowlands of southern Mesoamerica, and it is no accident that the best evidence for the earliest permanent villages in Mesoamerica comes from the Pacific littoral of Chiapas (Mexico) and Guatemala, although comparable settlements also have been reported from both the Maya lowlands (Belize) and the Veracruz Gulf coast.
The Barra (c. 1800–1500 BCE), Ocós (1500–1200 BCE), and Cuadros (1100–900 BCE) phases of the Pacific coasts of Chiapas and Guatemala are good examples of early village cultures. The Barra phase appears to have been transitional from earlier preagricultural phases and may not have been primarily dependent upon corn farming; but people of the Ocós and Cuadros phases raised a small-eared corn known as nal-tel, which was ground on metates and manos and cooked in globular jars. From the rich lagoons and estuaries in this area, the villagers obtained shellfish, crabs, fish, and turtles. Their villages were small, with perhaps 10 to 12 thatched-roof houses arranged haphazardly.
