Does Human History Need To Be Rewritten?

For some time I've entertained the idea ancient humans were much more knowledgeable than is usually given credit. So it was with great interest that I read about the 430,000 to 540,000-year-old mollusk with an etched-in zigzag pattern which has been getting attention.

Paleoanthropologist Dr. Stephen Munro bluntly suggests "it rewrites human history." Similar markings have been noted on previous artifacts, but those only date back 100,000 years. So it is being suggested that Homo erectus may have been more sophisticated than first thought.

So does the current understanding of history need a rewrite? It takes a lot for major adjustments to popular theory to be made. But I am encouraged by more and more findings that suggest the ancients were in fact very sophisticated.

For me the take away is the need to remain open-minded, and recognize that our knowledge about the distant past is fragmentary at best.
