We’ve seen that for each of these points, the current state of the science suggests quite clearly that science has no real idea what these observations might mean as far as cognition goes, or even if these observations are necessarily correct. Each one of these points could just as easily be linked with dolphin intelligence as opposed to dolphin stupidity, which is why both Manger and his opponents are able to offer seemingly endless reasons why their position should be regarded as the most parsimonious.

All we can really say at present is that the presence of VENs—like any other brain structures—are a mysterious signpost that science is yet unable to decipher.
