    The title is factually incorrect and is not what the research actually found:

    <a href="https:&#x2F;&#x2F;www.nature.com&#x2F;articles&#x2F;s41593-026-02433-7" rel="nofollow">https:&#x2F;&#x2F;www.nature.com&#x2F;articles&#x2F;s41593-026-02433-7

    Title: &quot;Two parallel neural ectoderm progenitors contribute to the developing brain&quot;.

    &quot;Hence, we postulate the brain is a composite organ emanating from two lineage-restricted progenitors; these dual progenitors may be evolutionarily conserved across 550 million years from hemichordates to mammals.&quot;
