Evidence of Human Presence in South America 21,000 Years Ago Detected Through Discovered Butchered Bones

Imprints left behind on the bones of a 21,000-year-old giant armadillo-like animal discovered in Argentina may be the oldest evidence of humans in southern South America.

If confirmed by further excavations and research, the discovery could push back the region’s possible human occupation to around 5,000 years ago, to the end of the last ice age.
