Archaeologists have unearthed a 700-year-old burial mound in Peru containing the remains of 76 sacrificed children and two adults, all with their chests cut open. The site is connected to the Chimú civilization that thrived from the 12th to 15th centuries. Researchers believe the victims were conquered people brought to work on the land and may have been sacrificed to strengthen the fields. The discovery suggests a complex system of sacrifice controlled by the central government.
