Darwin's Discoveries in Patagonia

In Patagonia, Darwin discovers a new Ria species, noting its differences from others. He observes the distribution of large and small Rias across the region, finding a clear pattern. Darwin also examines flightless birds like the steamer duck, which use their wings for non-flight purposes. Despite these observations, Darwin remains skeptical about species transformation, as living things appear constant over recorded history. However, he begins to question the difference between human experience and Earth's history.

What did Darwin notice about the Ria he discovered in Patagonia?

• It was larger than other Rias.

• It had a unique feather pattern.

• It seemed different from other Rias he had seen.

• It could fly short distances.

What does Darwin salvage from the Ria he discovered?

• The entire bird.

• Just the bones.

• Only the feathers.

• The wings, head, and much of the skin.

What puzzled Darwin about the distribution of Rias in Patagonia?

• The difference in their diet.

• Why the Rias were only found in the north.

• The clear yet inexplicable pattern of their distribution.

• Why the Rias were migrating south.

Which bird uses its wings as paddles?

• Ostrich

• Penguin

• Ria

• Steamer

What is unique about the steamer duck?

• It is the largest duck species.

• It has colorful feathers.

• It uses its wings to paddle.

• It can fly long distances.

Which bird uses its wings as sails?

• Penguin

• Steamer

• Ostrich

• Ria

What does Darwin find unclear about the design of flightless birds?

• Why they live in cold climates.

• Why an all-powerful Creator would design them with such unusual features.

• Why they are larger than other birds.

• Why they have colorful feathers.

What idea does Darwin remain committed to despite his observations?

• Species transform over time.

• Birds are the most evolved creatures.

• Species do not change.

• All birds can fly.

What challenges Darwin's previous beliefs about species?

• The migration patterns of birds.

• The vast history of life on Earth.

• The diet of Rias.

• The climate of Patagonia.

What does Darwin begin to understand about human experience?

• It is limited compared to the history of life on Earth.

• It is irrelevant to the study of species.

• It is the most important aspect of evolution.

• It is the same as the history of life on Earth.
