Final answer:
All vertebrates, except adult Homo sapiens, can breathe and swallow simultaneously.
Step-by-step explanation:
All vertebrates, with the exception of adult Homo sapiens, can perform breathing and swallowing simultaneously. Breathing refers to the process of inhaling and exhaling air, while swallowing refers to the action of moving food or liquid from the mouth to the stomach. These two actions are essential for vertebrates to obtain oxygen and nutrients for survival.
For example, imagine a fish swimming and feeding. It needs to continuously breathe by extracting oxygen from the water while simultaneously swallowing the food it catches. Similarly, a bird can breathe and swallow while flying.
