PLEASE HELP1!1!1!1!!1!1 How did the economies of the Incan Empire and ancient Maya differ?
The Inca collected taxes on all citizens, but the Maya collected only from farmers.
The Inca did not rely on trade, but the Maya did.
The Inca used barter, but the Maya did not.
The Inca did not have paper money, but the Maya did.

The Maya were native people of Mexico and Central America, while Aztec covered most of northern Mesoamerica between c. 1345 and 1521 CE, whereas Inca flourished in ancient Peru between c. 1400 and 1533 CE and extended across western South America. ... The Maya used two calendars. The Aztecs led a more brutal, warlike lifestyle, with frequent human sacrifices, whereas the Maya favoured scientific endeavours such as mapping the stars. The Inca were based much further south in the Andean region (home to modern-day Peru and Chile) and were accomplished builders.

Explanation:

as university of miami psychologists debra lieberman and adam smith pointed out in a recent article in the journal current directions in psychological science, humans have social and psychological mechanisms to deter incest. with very few exceptions, marriages between brothers and sisters and between parents and their children are verboten in every human culture. the primary psychological anti-incest mechanism is the yuck response. even the idea of sex with their mom or dad, bro or sis is upsetting to most people. the psychologist jonathan haidt has found that nearly everyone is repelled by the prospect of brother-sister sex, even in hypothetical situations in which there is no chance of pregnancy).

the biological cost of incest

this raises an interesting question: just what’s so bad about incest? sure, having sex with your dad or your sister seems gross — but why? some anthropologists have argued that incest taboos are learned social conventions. this explanation, however, doesn’t make sense to me as it does not explain the widespread existence of anti-incest mechanisms in creatures ranging from cockroaches to chimpanzees. second, the incest taboo is about as close to a universal law as human moral rules get.

why should mechanisms to avoid incest be so widespread both in nature and across human societies? the answer is simple. the problem with having sex close with relatives is that there is an astonishingly high chance that your offspring will be born with a serious birth defect.
