Read the passage. Scientists long believed that the discovery of a mummy in the Alps, known as Ötzi the Iceman, provided information on how humans lived 5,300 years ago. More recently, scientists used DNA analysis to discover that Otzi and modern-day humans have DNA markers in common. How did the study of Otzi's DNA change the way scientists viewed the development of modern humans? O They learned that Ötzi the Iceman was a close relative of today's humans. They learned that early humans developed differently and died off from the cold. O They learned that the DNA found in early humans can be found in today's humans. O They learned that the DNA of early humans was much older than they originally believed.
