Question 1

Which of the following best describes Darwin's definition of evolution as presented in 'The Origin of Species'?

Accepted Answer

Evolution is descent with modification, where species accumulate differences from their ancestors as they adapt to different environments over time.

Question 2

According to the study materials, which scientist developed the two-part, or binomial, format for naming species that is still used today?

Accepted Answer

Carolus Linnaeus

Question 3

What is the main difference between the scala naturae and Linnaeus's classification system?

Accepted Answer

Scala naturae arranged organisms on a ladder of increasing complexity, while Linnaeus used a nested classification grouping similar species into broader categories.

Question 4

Which principle did Lamarck propose to explain how organisms change over time?

Accepted Answer

Inheritance of acquired characteristics

Question 5

Why is Lamarck's mechanism for evolution considered incorrect based on modern genetics?

Accepted Answer

Traits acquired during an organism's life are not inherited by offspring as Lamarck proposed.

Question 6

Which scientist is credited with developing paleontology and noting that older strata contain fossils more dissimilar to current life-forms?

Accepted Answer

Georges Cuvier

Question 7

How did Hutton's and Lyell's ideas about geology influence Darwin's thinking about evolution?

Accepted Answer

They suggested to Darwin that slow, continuous processes could produce substantial biological change over long periods.

Question 8

Which of the following best illustrates the unity of life as described in the study materials?

Accepted Answer

All mantises share certain features such as three pairs of legs and triangular heads.

Question 9

What does the pattern of evolutionary change refer to?

Accepted Answer

Observations and data from scientific disciplines showing that life has evolved over time.

Question 10

Which of the following is a real-world example supporting gradualism in geology, as discussed by Hutton and Lyell?

Accepted Answer

The formation of the Grand Canyon by river erosion over millions of years.

Question 11

Which equation best represents the concept of change in genetic composition of a population over time?

Accepted Answer

$$\Delta p = p' - p$$

Question 12

In the context of sedimentary strata, which layer would you expect to find the most recent fossils?

Accepted Answer

The uppermost (youngest) stratum.

Question 13

Which of the following is NOT a key observation about life that Darwin sought to explain?

Accepted Answer

The sudden creation of all species at once.

Question 14

Which scientist's explanation of the fossil record involved catastrophic events causing extinctions?

Accepted Answer

Georges Cuvier

Question 15

Which of the following is a testable scientific hypothesis according to the study materials?

Accepted Answer

Cuvier's explanation that boundaries between strata represent catastrophic events.

Question 16

If a scientist finds a fossil in a lower stratum, what can they infer about its age compared to fossils in an upper stratum?

Accepted Answer

The fossil in the lower stratum is likely older.

Question 17

Which of the following best describes the process of evolution?

Accepted Answer

The mechanisms that cause the observed pattern of change in species over time.

Question 18

Which real-world scenario refutes Lamarck's principle of inheritance of acquired characteristics?

Accepted Answer

A bonsai tree shaped by pruning does not pass its shape to its offspring.

Question 19

Which of the following statements about scientific theories is supported by the study materials?

Accepted Answer

Scientific theories are continually tested by examining whether they account for new observations and experimental results.
