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
penguins with short wing had an advantage
penguins with long wings were able to swim longer to get more food
penguins with shorts wings were more easily picked off by predators
penguins with long wings were considered better mates
penguins with short wings were stronger swimmers and able to envade predator better
Conclusion supported by data:
1. Penguins with short wings have increased in population from 1900 to 2000.
2. Penguins with long wings have decreased in population from 1900 to 2000.
3. The data shows a correlation between wing length and population changes over time.
Conclusion not supported by data:
1. Penguins with short wings have always had a larger population than penguins with long wings.
2. The increase in the population of penguins with short wings is directly related to their inability to fly.
3. The decrease in the population of penguins with long wings is directly related to their inability to dive deep and store food reserves.
Conclusion Supported by Data:
1. Penguins with short wings had an advantage.
3. Penguins with short wings were stronger swimmers and able to evade predators better.
Conclusion NOT Supported by Data:
2. Penguins with long wings were able to swim longer to get more food.
4. Penguins with long wings were considered better mates.
5. Penguins with short wings were more easily picked off by predators.
