More modern North American celts / axes are found on the web site below ae made in a combination of ways, most made entirely or finished by a pecking and grinding method as opposed to just being made exclusively via percussion- but it's interesting and informative:
And percussion flaking andesite is not easy as most posters on here seem to think. I could probably bang a similar one out in 30-60 minutes, given the right hammer stone, but most people wouldn't have a clue how to even start.
very, very slim, which is still astronomically higher than the odds of say, the sophistication of my DNA or my eyeball alone, evolving, eh?
If science can talk about "codes" within parts of our bodies and within nature minus acknowledging a code-maker, then I think we can start talking about a lot of archaelogical discoveries across the board that may appear to have been of human origin, but were simply of natural origin.
Increasing complexity, after all, is the standard earmark of scientific discovery. That is the condeded pattern.
So, mark this equation: Any rudimentary object is the potential ancestor/parent of increasingly complex objects. The totally unsophisticated can morph into the sophisticated, as long as your recipe has "enough" time (whatever that is).
So, 500,000 years for nature to work on an axe head? Oh, a few scratchings are a piece of cake in comparison to the wonder and awe of the worksmanship of our own bodies!
What? You don't believe my description about your unsophisticated, multiple great-grandthing as your original ancestor? All ya need to do is take a leap of faith like most normal scientific evolutionists, preaching at a university pulpit near you!
