## Resource

For years, scientists have puzzled over one of the most famous features in dinosaur history. Were those little arms useful? Were they a mistake of evolution? Or did they serve a secret purpose? In this Squiz Kids Science Short, we explore brand-new research suggesting that some giant meat-eating dinosaurs evolved powerful heads and jaws that made their arms less important over time. Along the way, we discover that evolution just needs to be good enough, and find out why tiny arms may have been a surprisingly successful design choice. 🎧 A quick, fascinating science fix for curious kids and their grown-ups.
