Penguins have evolved from birds that used to fly. At some stage, the penguin ancestors became increasingly adept at swimming and lost the ability to fly. In the trade-off, their short, powerful wings make excellent flippers for "flying" underwater, being less fragile and creating less drag than the long wings of many other seabirds. Another advantage of giving up flight is that they can put on weight. The ability to store food reserves as fat is an advantage for birds that have to travel far to obtain food, and larger penguins can dive deeper and for longer.

Conclusion Supported by Data Conclusion NOT Supported by Data

Answer 1

Supported by data:

1. Penguins' short, powerful wings are well suited for swimming underwater.
2. Penguins have the ability to store food reserves as fat.
3. Larger penguins can dive deeper and for longer.

Not supported by data:
1. Penguins evolved from birds that used to fly.
2. Penguins lost the ability to fly in order to put on weight.

Answer 2

are penguins with short wings easaly picked off

Answer 3

Based on the information provided, penguins with short wings may be at a disadvantage when it comes to flight, but their short, powerful wings are well suited for swimming underwater. Penguins' adaptations to their environment allow them to thrive and survive, despite not being able to fly. So, in this context, penguins with short wings are not easily picked off.

Answer 4

is penguins have longer wings dose that mean they ca swim longer to get more food

Answer 5

No, having longer wings would not necessarily mean that penguins can swim longer to get more food. In fact, the article mentioned that penguins evolved shorter, more powerful wings that are well suited for swimming underwater. This adaptation allows them to dive deeper and for longer periods of time to search for food, despite not being able to fly. So, the length of their wings is not directly related to their ability to swim longer and obtain more food.
