I just saw Apocalypto, I thought the Aztec were the only civilization doing human sacfrifices?

I saw Apocalypto a couple of times , i think but iam not to sure that maybe the Mayans also did human sacrifices , their is also the olmecs and the incas . The Aztec's , Mayans , and the Inca's were the three greatest native american civilzation to exist . They thrive in what is called the " Pre - Columbian " era - or i think . I do not know if the inca's or the olmecs did human sacrifices or not , try going to wikipedia.com
