What are some things about otzi the icemans culture?

They were apparently more technologically advanced than other groups in the same time period that we had studied before. His Copper head axe was thought not to have existed for another several hundred years.

Human Blood on his clothing showed that he apparently carried someone who was wounded. The fact that he still had all of his equipment (especially his invaluable and very modern axe)and some food shows that he probably outlived his killer. There was also human blood on several of his arrows which was different from that on his clothing.
