Final answer:
Otzi the Iceman likely died from bleeding out after being hit by an arrow that pierced a major artery, coupled with a head injury, both of which were discovered on his preserved remains.
Step-by-step explanation:
Forensic scientists believe that ""Otzi", the five-thousand-year-old iceman discovered in the Alps, most likely died from an arrow wound to the shoulder that hit a major artery, leading to his death. His body was found well-preserved in the glacier, and upon examination, it was discovered that the arrowhead was still lodged in his shoulder. This wound would have caused him to bleed to death, and this trauma supplemented by the cold conditions likely lead to his demise. Additionally, a deep cut on his hand was identified, which would suggest he was involved in hand-to-hand combat close to his time of death. Evidence of blunt force trauma to his skull was also noted; however, the arrow wound is considered the fatal injury that caused his death.
