What a way to oversell the discovery.
The reality is:
```
    * Different brain regions have different functions: ancient knowledge.
    * Different regions contain distinct cell types and molecular programs: also well established.
    * Anterior and posterior brain structures may trace back to fundamentally separate progenitor lineages that were independently specified very early in evolution and development: that&#x27;s the interesting new result.
```
The headline should have been: "Human forebrain and hindbrain arise from distinct embryonic progenitor lineages" - not that we have "two organs" in the brain.

  Oh, I think we could crank that headline even harder while still keeping one toe on the truth. For example:
  "Elon Musk's Brain is Two Separate Organs"

    People with maternal Jewish DNA have two brains.
