This development subsequently led to a reduction in the forelimb size of these predators, a phenomenon observed independently across five distinct theropod lineages. Tyrannosaurus rex, an apex predator with a massive skull and famously diminutive arms, is a prime example of this evolutionary trend. Lead author Charlie Scherer explained that natural selection prioritized stronger heads for hunting, rendering forelimbs less essential and leading to their reduction. The precise function of T. rex's small arms remains a puzzle, with researchers suggesting they might be vestigial structures maintained due to complex genetic factors.
