For over a century, the comically undersized arms of Tyrannosaurus rex and its theropod kin have posed one of evolution's most humbling riddles — a reminder that nature does not always optimize neatly, and that the most fearsome creatures can carry within them the quiet signatures of compromise and accident. Scientists have proposed everything from sexual display to survival strategy to simple evolutionary neglect, yet no single answer has prevailed. The fossil record, rich as it is, preserves bone but not behavior, leaving us to reason carefully at the edge of what can be known.
