The origin of civilization in Peru is similar to that of the river valley civilizations of Egypt and Mesopotamia is that both civilization settled in areas that were on rivers, this gave the people access to water which needed to live, transport goods and people, and most importantly plant crops. Because they were both by rivers the land was fertile which is a plus for settling in a location and not to mention of the individuals settling were not the first to think the area was great animals and plants thrived and lived in the area which is another food source. The people saw that plant and animal thrived in this area so they should be able to live in this area as well with ease. 

Assemblies do not have written codes of laws. laws are matters for magistrates and courts, not assemblies. codes of law are things such as civil law, criminal law, and constitutional law. what assemblies have are procedures regarding debating, voting and other business they might carry out.  also note that rome had three assemblies: the assembly of the soldiers, the assembly of the tribes, and the plebeian councils.
