For over a century, the Tyrannosaurus rex stood as one of nature's great paradoxes — a supreme predator rendered almost absurd by its diminutive arms. A new paleontological study has resolved this enduring puzzle, revealing that those small limbs were not a failure of design but a consequence of evolutionary economy, where the body's most critical systems claimed priority over all else. The finding extends across the broader theropod family, suggesting that as these ancient carnivores grew larger, the shrinking of their arms followed a consistent and logical principle.
