An experiment could be as simple as introducing interesting artifacts into cetaceans' habitats and observing if (and how) different species interact with them.
Oddly, evidence is viewed differently when produced by cetaceans and birds.
Another difference occurs in the plates relating to the cetaceans.
This conclusion is relevant for the broader consideration of what amounts to culture in cetaceans.
Such versatility raises the question of how widely social learning is used in less studied species of cetaceans.
Finally, the authors' account of the evolution of cetacean culture stresses that there are likely to be interesting interactions between migration and culture.
First, culture may be an ancestral state predating the cetacean split from their terrestrial ancestors.
Culture may be an ancestral characteristic of terrestrial cetacean ancestors; not derived via marine variability, modern cetacean mobility, or any living cetacean social structure.
