16 Questions
Which of the following is NOT a clue about ancestry and relationships used in classifying organisms according to the text?
Variation of species
Why are whales classified as mammals, even though they are aquatic creatures like fishes?
Whales have common ancestry with other mammals
What is the primary evidence provided in the text for the theory of evolution through natural selection?
All of the above
What is the limitation of using morphology and homology as evidence for common ancestry?
Morphology and homology do not always provide 100% certainty about common ancestry
What is the main purpose of discussing rudimentary or vestigial organs in the context of evolution?
To support the idea that organisms can lose certain organs or body parts through natural selection
What did Darwin observe during his voyage that inspired his theory of evolution by natural selection?
Variations in the shapes and sizes of shells of tortoises and finches on different islands
Which scientist stated that the orbits of the planets, including the Earth, are traced in eccentric ellipses?
Johannes Kepler
Who took Darwin to Wales on a geologic field trip in 1831?
Rev. John Stevens Henslow
What did Charles Darwin study at Christ’s College, Cambridge?
The observations of wildlife on the Galapagos Islands
Which contribution is associated with Galileo Galilei?
Seen moons of Jupiter and phases of Venus through telescopes
What significant observation did Darwin make about tortoises and finches during his voyage?
Variations in the shapes and sizes on different islands
Which of the following is NOT a factor that contributed to the differences observed in the Galapagos Tortoise species according to the text?
Differences in the geographic location of the islands they inhabit
Which of the following best explains why the long-necked Galapagos Tortoises in dry areas have longer necks than the short-necked Galapagos Tortoises in wet areas?
The long-necked tortoises need to reach higher for food, so their necks have adapted to become longer.
How did the differences in the Galapagos Finch species' beak sizes and shapes come about?
The Galapagos Finches' beak sizes and shapes adapted to the specific food sources available in their environments.
Which of the following best explains why the long-necked Galapagos Tortoises in dry areas have longer necks than the short-necked Galapagos Tortoises in wet areas?
The long-necked tortoises need to reach higher for food, so their necks have adapted to become longer.
Which of the following best explains the differences observed in the Galapagos Iguanas?
The Galapagos Iguanas evolved different physical characteristics to adapt to the varying climates and environments of the Galapagos Islands.
Test your knowledge on Darwin's argument for the common ancestry of life and natural selection as the cause of speciation. Explore evidence of evolution related to natural selection, including clues from classifying organisms, genetic variations, common ancestry examples like fishes and whales, and morphology evidence such as homology of basic structures.
