I believe the key here is "figuring out" - choosing a particular behaviour in a setup not found in natural setting. If a particular behaviour is hardcoded in DNA (e.g. bees building hexagonal cells), you cannot say it's been figured out.

Well, maybe by the evolution but not the animal.

The usual explanation of those behaviors is that they are "emergent", i.e. individual agents are "dumb" but the dynamics of the whole system leads to complex behaviors. Another example is ant colonies.

Human experimenters are full of themselves. See recent experiments in self awareness in crows / apes / etc.

The vivesectors would have it that it's ok to use animals because they are lower forms of life and yet assert that doesn't affect the results!
