tzi and Diplodocus
Hi, Tram law.
I remember learning about the "Iceman" in class when he was first discovered. I was in fourth grade. Unfortunately, I didn't remember any of the details, so I had to go and read the Wikipedia article.
It contains this gem:
tzi's copper axe was of particular interest, as it was the only complete prehistoric axe ever discovered. About two feet long, the axe's shaft was made from yew tree bark, while the handle of the axe was made from yew branch and leather binding. The copper axe blade extended out of the leather binding and was about one inch long. tzi was 5,300 years old, and humans were not thought to have discovered copper for another 1,000 years, forcing archaeologists to re-date the copper age.
A couple of things to note are that (1) copper and bronze are not the same thing, nor are the "Copper Age" and the "Bronze Age."; (2) when humans developed copper technology really has very little (if anything) to do with the Theory of Evolution.
And, in response to your friend's comments about dinosaurs, Diplodocus did exist. He must have been thinking about Brontosaurus: this was a case in which a paleontologist described two dinosaur fossils as two different species, then later found out that they were the same species. Thus, Brontosaurus, the more popular name for the dinosaur, is not considered a valid name in science, because it is predated by Apatosaurus.
On top of that, when Brontosaurus was first found, the specimen lacked a head, so, museum personnel who were trying to make the first ever display of a sauropod dinosaur used the head of similar dinosaurs as a model. As it turns out, the head design they had used was wrong. But, the display had been so popular (it was, at the time, the biggest dinosaur ever known), that the name "brontosaurus" and the conjectural anatomy, became more well-known than the correct name and anatomy.
I think this must have been what your friend was talking about. And, as you can see, it really has nothing to do with the validity of the Theory of Evolution, either.
