Instructions

Check your understanding of concepts from 8·1 Evolution is an ongoing process, and 8·2–8·4 Darwin journeyed to a new idea by answering the following questions.

1.

1. Which of the following statements about Charles Darwin is INCORRECT?

He and Alfred Russel Wallace independently came up with the theory of evolution by natural selection.

He married his first cousin.

He dropped out of medical school.

He spent five years traveling the world observing living organisms and collecting fossils.

He influenced Malthus's ideas about the limits of population growth.

Correct. (See section 8·4 Observing geographic similarities and differences among fossils and living plants and animals, Darwin developed a theory of evolution.)

Incorrect. (See section 8·4 Observing geographic similarities and differences among fossils and living plants and animals, Darwin developed a theory of evolution.)

2. A population is:

a group of individuals of the same species that live in the same general location and have the potential to interbreed.

a group of individuals of the same species that have the potential to interbreed.

a group of individuals of the same species that live in the same general location and have the same genotypes.

a group of species that share the same habitat.

always clearly defined.

Correct. (See section 8·1 We can see evolution occurring right before our eyes.)

Incorrect. (See section 8·1 We can see evolution occurring right before our eyes.)

3. Charles Darwin spent time on the Beagle:

as part of his medical school curriculum.

because his father was a silk trader, transporting cargo around the world.

as part of his research while writing his thesis for theology school.

after graduating from college, while serving as the companion to the captain on the surveying ship.

as part of his research while writing The Origin of Species.

Correct. (See section 8·3 A job on a ’round-the-world survey ship allowed Darwin to indulge his love of nature and make observations that enabled him to develop a theory of evolution.)

Incorrect. (See section 8·3 A job on a ’round-the-world survey ship allowed Darwin to indulge his love of nature and make observations that enabled him to develop a theory of evolution.)

4.

4. While on the Beagle, Darwin was intrigued by glyptodonts because:

he believed that if he could not complete the curriculum for medical school, he would enjoy studying dentistry.

glyptodont fossils resembled a species that currently existed, but were much, much larger.

glyptodont fossils varied in size across the different islands in the Galápagos archipelago.

armadillos occurred in Africa, but not South America. Glyptodont fossils in South America revealed that the two continents had once been joined.

their dental structures indicated that they consumed seeds much larger than those produced by any species of plant currently found on earth.

Correct. (See section 8·4 Observing geographic similarities and differences among fossils and living plants and animals, Darwin developed a theory of evolution.)

Incorrect. (See section 8·4 Observing geographic similarities and differences among fossils and living plants and animals, Darwin developed a theory of evolution.)

5.

5. Which of the following does NOT describe a way that scientific understanding of the world has changed following the publication of The Origin of Species by Charles Darwin?

Changes acquired by individuals during their lifetime are passed on to their offspring.

Earth is more than 6,000 years old.

Some species of organisms go extinct.

The geology of earth is not constant, but instead is always changing.

Populations of organisms can change over time.

Correct. (See section 8·4 Observing geographic similarities and differences among fossils and living plants and animals, Darwin developed a theory of evolution.)

Incorrect. (See section 8·4 Observing geographic similarities and differences among fossils and living plants and animals, Darwin developed a theory of evolution.)
