Answer:
They learned that the DNA found in early humans can be found in today's humans.
Step-by-step explanation:
Given that DNA analysis demonstrated that Ötzi the Iceman (the mummy in the Alps found between Italian and Austrain border) is virtually like a modern human, even though, he lived in the long past at more than 5,000 years ago.
He exhibits similar physical characteristics to modern man, except that he is shorter in height compared to modern man.
Hence, it can be concluded that the study of Ötzi's DNA change the way scientists viewed the development of modern humans in way that " the DNA found in early humans can be found in today's humans."
