b. Discovery of Ötzi the Iceman

Explanation:

One chance led to the discovery of a 5,000-year-old mummy frozen and buried in the Tyrol Alps on the border between Italy and Austria. She was baptized as Ötzi, the iceman, for being found in the Ötzal massif. The discovery sparked a lot of research by scholars from various fields, pointing to the great importance of the discovery, as it is one of the few well-preserved mummies found in Europe.

Keeping his body at low temperatures made it possible to know that he was a man who was between 40 and 50 years old when he died, a keeper of curly and brown hair, still growing a beard. This knowledge was obtained from the hairs found on their clothes and objects. There were also tattoos that adorned the painful points of his body caused by a possible arthrosis. These charcoal marks may indicate a body knowledge similar to Chinese acupuncture, as the marks are in places that are also indicated by this branch of oriental medicine.

We also found objects that could present details of the living conditions of humans during the Neolithic. Ötzi was dressed in clothes made of goatskin, deer, and bear, sporting a leather pouch around his waist, where a scraper, a drill, a flint blade (rock used for making instruments), a bone needle, a Stone grinder and some fungi, possibly used for medicinal purposes.

The discovery of the ice man has changed some original scientists' thoughts about humans, and created and proven new thoughts that we now accept as true.
