Since when did banging something against a rock count as tool use? Surely by that measurement any creature that scratches itself against a post or takes refuge under a tree is a tool user. Many creatures make nests - is that a tool?
If a fish was dropping a stone onto a clam I would accept it as a very primitive form of tool use. Just.
- derleth 15y agoI think the most reasonable cutoff of what is tool-use is that tool-use must be learned, and not just instinctive. I think that excludes nest-making but includes all of the interesting things ravens do with rocks and sticks.
