Terrible headline, cool research.

The brain is a composit of cells from two lineages that separate very early in development and reflect a deeper spatial and functional separation deep in the history of metazoan (read: animal) evolution.

Tying all this to humans specifically is just confusing. This is something that’s seen in a substantial portion of animals, and as such has nothing to do with “ poetry, mathematics and wondering about our own origins”. These features of humans evolved hundreds of millions of years after this two lineage composite organization of animal brains evolved.

I wish the article hadn’t gone out of its way in confusing these issues to push the “relevance” of the research. It’s a pretty remarkable finding anyway.
