For over a century, science has told us that bodies led and brains followed — that the Cambrian Explosion's riot of animal forms demanded, and therefore produced, ever more sophisticated nervous systems. Now, a researcher proposes inverting that causality: neural complexity may have arrived first, quietly preparing the conditions under which the great diversification of animal life became possible. If the brain was not evolution's response but its instrument, then the story of life's sudden flowering must be rewritten from its very first chapter.

Bias & Framing
⚖
Article presents a speculative scientific hypothesis with neutral framing, though the sensationalized headline 'What if the brain came first?' may overstate the certainty of the challenge to conventional understanding.
Bias Direction
center
Confidence
MED
The headline uses a provocative rhetorical question to generate interest in a contrarian scientific proposal, while the body text appears to present it as one scientist's challenge to conventional theory rather than established fact.
