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's 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?
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.
they learned that the dna found in early humans can be found in today's humans.
they learned that the dna of early humans was much older than they originally believed.
