Penguins are flightless birds because their bodies have evolved for swimming rather than flying. Their wings have become flippers, and their heavy bones and dense muscles make them efficient underwater hunters, but these adaptations prevent them from taking to the air.
Why Buses Have No Seatbelts
Buses do not have seatbelts because they are designed for short urban journeys with frequent stops, where passengers are less likely to be involved in high-speed collisions. Additionally, seatbelts would hinder quick entry and exit, and the high-backed seats provide a protective structure in the event of a crash.
