It’s not disgusting at all. For one thing, the man was not formally buried but left dead, perhaps even murdered and was under snow and ice for 5,000 years. We can gain a lot of knowledge from this autopsy.
For instance, they found that he had coronary artery disease and Lymes disease. Heart disease has been thought to be the result of our modern life style and diet but this goes to indicate that there may be a stronger genetic component that may result in new research. Knowing that he had Lymes tells us a lot about the genetic makeup of the bacteria that causes the disease that plagues so many in modern times. Knowing more about his diet and his physiology is useful.
Just astonishing what they can do with genes today. They could tell by a marker that Otsi had brown eyes. Said his closest relatives today are found on (I think) Sardinia.
They have techniques that give them as much information in 3 days as would have taken 3 years a half a decade ago. And 10 years ago they couldn’t even imagine doing these tests.
