When people entered a cave in Chiapas, Mexico, in 2012, they found 165 human skulls

Not all findings in history lead us to an answer; some leave us grappling with even more questions. Human remains have long opened up a range of curious questions: what happened, why, and who were these people?

More often than not, they open the pathway for researchers to learn what beliefs and traditions shaped community life and even death.But sometimes, what appears to be a familiar archaeological finding can turn out to tell a rather different story.
