Question 1

Which of the following best describes typological thinking as proposed by Plato?

Accepted Answer

Species are fixed and unchanging, with each individual being a perfect representation of its type.

Question 2

According to Lamarck's theory of evolution, how do organisms acquire new traits?

Accepted Answer

By inheriting characteristics acquired during their lifetime.

Question 3

Which of the following is an example of Lamarckian thinking?

Accepted Answer

A blacksmith develops strong arms from work, and his children are born with stronger arms.

Question 4

Why was the voyage of the HMS Beagle, especially the study of Galápagos finches, important to Darwin's theory of evolution?

Accepted Answer

It provided evidence of variation and adaptation among closely related species on different islands.

Question 5

Which of the following is NOT one of the four main steps of natural selection?

Accepted Answer

Inheritance of acquired characteristics

Question 6

Which two main mechanisms generate genetic change in populations?

Accepted Answer

Mutation and sexual recombination

Question 7

A population of bacteria is exposed to an antibiotic. Some survive due to a random genetic change, and their descendants are resistant. Which evolutionary mechanism is primarily responsible for this change?

Accepted Answer

Mutation

Question 8

Which statement best distinguishes adaptation from acclimation?

Accepted Answer

Adaptation is a heritable trait that increases fitness, while acclimation is a temporary physiological change.

Question 9

Why is the phrase 'survival of the fittest' considered misleading in the context of natural selection?

Accepted Answer

It suggests only the physically strongest survive, rather than those best suited to their environment.

Question 10

Which of the following is an example of a vestigial structure in humans?

Accepted Answer

The appendix

Question 11

Which principle states that geological processes occurring today are similar to those that occurred in the past?

Accepted Answer

Uniformitarianism

Question 12

The Law of Superposition is used to:

Accepted Answer

Determine the relative ages of rock layers and fossils.

Question 13

Which of the following is an example of a homologous structure?

Accepted Answer

The forelimbs of whales, bats, and humans

Question 14

Artificial selection differs from natural selection in that:

Accepted Answer

Humans choose which traits are passed on in artificial selection.

Question 15

Which of the following best describes a transitional fossil?

Accepted Answer

A fossil that shows intermediate characteristics between ancestral and derived species.

Question 16

Which scenario best illustrates the concept of heritability in evolution?

Accepted Answer

A trait that increases an organism's fitness is passed on to its offspring through genes.

Question 17

Which of the following is a direct observation supporting the theory of evolution?

Accepted Answer

The development of antibiotic resistance in bacteria over a few decades.

Question 18

Which of the following best explains why genetic variation is important for natural selection?

Accepted Answer

It provides the raw material for selection to act upon, allowing populations to adapt to changing environments.

Question 19

Which of the following best describes sexual recombination?

Accepted Answer

The process by which offspring inherit a combination of genes from both parents, increasing genetic diversity.

Question 20

A paleontologist finds a fossil with both fish-like and amphibian-like features. According to the Law of Superposition, what can be inferred if this fossil is found in a rock layer below a layer containing only amphibian fossils?

Accepted Answer

The transitional fossil is older than the amphibian fossils.
