how might the cultures of latin america be different if the spanish and portuguese had never arrived? what kind of culture do you think would dominate the region today?

Wow a lot of things would not be the same. First of all a completely different culture would be dominant. But to say if the Spanish and Portuguese never arrived language would probably be different. They also brought along religion and many different life style choices that changed people.  There was an idea that when the Spanish "invaded" They brought along germs that at one time killed of hundreds of people but eventually built up their immune systems they brought over weapons or steel, and they showed people different ways to find food, shelter and protection. Hoped this helped!
