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 Ötzi and modern-day humans have DNA markers in common.How did the study of Ötzi’s DNA change the way scientists viewed the development of modern humans?
Answer
A
They learned that Ötzi the Iceman was a close relative of today’s humans.
B
They learned that early humans developed differently and died off from the cold.
C
They learned that the DNA found in early humans can be found in today’s humans.
D
They learned that the DNA of early humans was much older than they originally believed.
Explanation
Scientists found that Ötzi’s DNA markers are also present in modern-day humans. This showed that DNA from early humans can still be found in people today, which matches choice C. The passage does not say that Ötzi was a close relative of modern humans or that early humans died off from the cold.
