For over a century, the comically small arms of Tyrannosaurus rex have stood as one of paleontology's most enduring riddles — a creature of immense power seemingly betrayed by its own anatomy. New research now frames those diminutive limbs not as a failure of design but as the quiet signature of a deeper evolutionary logic: when the head becomes the ultimate weapon, the arms simply cease to matter. Across the great theropod lineage, nature appears to have made the same ruthless bargain repeatedly, trading versatility for dominance.
