The Battle of Limbs: Debating the Importance of Legs vs. Arms
The importance of legs versus arms depends on the species. For humans, legs are crucial for mobility and survival, while arms are less essential. However, individuals with amputations have shown that it is possible to thrive without certain limbs. In the case of Tyrannosaurus rex, their small arms were likely a result of evolution prioritizing their large heads and jaws. For birds, wings are vital for flight and are often the largest part of their bodies. Flightless birds may reduce their front limbs, except for swimming purposes. Some species, like snakes and worms, have evolved to be limbless, as it allows them to catch prey or move more efficiently.
