Re: Parsimony is a virtue in science, but not in paleoanthropology
No one wants to cast doubt on a $uccessful theory.
I recently paid Alta Museum $14 to view the spectacular rock art on the smooth sandstone rocks near the fjord. It is a UNESCO World Heritage site. During the summer months, up to a thousand visitors each day pay to view those carvings. It is said that the carvings were made by Alta residents during many periods ranging from 7000 to 2000 years ago.
I have worked a lot with rocks, and have seen a lot of art made by various artists. My wife and children are artists. I can't accept the anthropologists' interpretation that the rock art of Alta was made by different people during vastly different ages, using only rocks as tools. I think that the engravings were made by a few visitors, who drew the figures and then used a hammer and iron chisel to engrave them. Rock engravings at different sites along Alta fjord have different artistic styles, and were probably made by different artists at about the same time.
If the artists used iron tools, it was during the iron age, not the stone age. I think the engravings were done by Viking-age visitors who came by boat during the summer months. Many of the boats that are depicted have animal heads on the prows, typical of the Viking culture. A Viking-age hypothesis has not been mentioned by anthropologists who study the site. That is because it would diminish the public interest in it.
