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.

  Often the headline is not created by the author of the article.
  Also newspaper headlines used to give a quick summary of the story, online articles as you say, clickbait.

    can confirm from experience that the headline and press release were likely 100% from Stanford’s comms department and the authors are likely panicking about the hyperbolic spin
