Thread:Comments:New studies may bring slug-made glues closer to use in medicine/Usage in nature/reply (2)

That's handy, though I was looking for how animals use slugs for healing their wounds. I know they use some plants for healing wounds but using slugs is pretty new.

But then a few months ago we watched a movie by BBC, in which the authors reported usage of a saw by a monkey as an extraordinary example of intelligence of animals that was allegedly not seen before. They gave lots of other clever behaviour examples, such as usage of particular flowers to support their diet, creation of an nicely designed circular underwater nest by a fish, etc etc. While these examples are indeed impressive, I was disappointed by such a saying: birds use sticks for creating their nests for many centuries, and implying that usage of tools is unique to man until BBC showed otherwise sounded absolutely frustrating and misleading.
