Ötzi arrived in 1991 bearing gifts from a much earlier time. His well-preserved body was discovered in a receding Italian glacier, and it became the subject of intense study. Researchers learned from that analysis that it was difficult to live five thousand years ago. Ötzi showed signs of having endured arthritis and other afflictions, and there was an arrowhead in his shoulder. But his copper ax showed that people were somewhat advanced. His tattoos suggested value was placed upon ornamentation or the use of acupuncture, a practice previously thought to have begun two thousand years later. Researchers have unlocked much about human evolution from the key that Ötzi handed them.
