Given the parallel example cited in the article of jellyfish having two spatially separate organs, & the subsequent speculation that our own ancestors could also have had spacially separate anterior & posterior masses, the title doesn't really seem unreasonable in its hyperbole.
While it might not be perfectly accurate it's hardly misleading.
Humans also have a gut brain. So maybe we have 3 seperate brains?
The most important question: are they all conscious?
I found the title confusing, at the very least because it can be argued that the two brain hemispheres are two organs already, as they operate independently when severed from each other.
