and here is the evolution of plastic cutlary. as you can see it pretty much started out as more or less a straight line, and over millions of years of geologic pressure, it formed a somewhat of a cup thing at the end. we know that the grooves were formed last, but it wasn't until recently that we discovered the missing links between these two.
and here are the missing links we found.
not only that but it was also found that all of these are made up of 100% the same material.
