For over a century, the Tyrannosaurus rex stood as one of nature's great paradoxes — a supreme predator encumbered, it seemed, by arms too small to serve any obvious purpose. New research now resolves this tension not as evolutionary misfortune, but as elegant efficiency: as the creature's skull grew into an unrivaled weapon, the arms simply ceased to matter. In the calculus of natural selection, redundancy is quietly retired, and what looks like a flaw may in fact be the signature of deep specialization.

Article presents scientific research on T. rex evolution with sensationalized headlines across outlets; minimal bias in core content but framing varies from neutral to dramatic.

MED
Sensationalism through headline variation - outlets use dramatic language ('Brutal Reason,' 'Shrimp Arms,' 'mystery solved') to frame straightforward paleontological research as surprising discovery, though the underlying science remains consistent across sources.

HIGH
No direct consumer impact. This is academic paleontology research with no bearing on household finances, purchasing decisions, or economic welfare.
No economic policy implications. May indirectly support science funding and museum/education budgets, but represents negligible macroeconomic impact.
