Lying is always a bad choice. The paper in Nature says
"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."
If they had written instead:
"Human brain was two separate organs"
Then, both attention grabbig and true?
Human Brain Evolved From Two Separate Organs.
Probably not, because by the time hominids were a thing, it was one.
(if I'm reading parent poster correctly)
Are there other composite organs?
Does the adrenal gland count?

That isn't even remotely related to the parent question. Organisms =/= Organs.
Do you think siphonophores don't have organs?
Yes, but this is left for the next years because they give only one Nobel preis per year.
