Traces of blood and fragments of muscle, tendon, skin and hair found on 2,000-year-old stone knives have given researchers the first conclusive evidence that the obsidian blades were used for human sacrifice so long ago in Mexico.
Researchers in Mexico announced Wednesday that they have found blood cells and fragments of muscle, tendon, skin and hair on 2,000-year-old stone knives, calling it the first conclusive evidence from a large number of stone implements pointing to their use in human sacrifice.
"These finds confirm that the knives were used for sacrifices," Mainou said.
For example, some knives in the test had more traces of red blood cells, while others had more skin, and others more muscle or collagen, "which suggest that each cutting tool was used for a different purpose, according to its form," Mainou said.
