In terms of the ethological findings,some distinction must be made between

There is a Goodall segment in The Brain or The Mind video series that illustrates the issue you are raising.  In it, you can see one of the chimps taking a branch with leaves, running his closed hand down the branch to strip it of leaves, then sticking it into the nest. This is more than serendipitous and more like the fixed-action pattern you denied existed in Goodall's discussion of tool-making by the chimps.
