Question 1

Which of the following statements best describes the scientific meaning of 'theory' in evolutionary biology?

Accepted Answer

A theory is a well-substantiated explanation of some aspect of the natural world, based on a body of evidence and repeatedly tested.

Question 2

Which misconception is illustrated by the statement: 'Evolution is just an unproven theory'?

Accepted Answer

Confusion between scientific and everyday use of 'theory'

Question 3

Why is the statement 'Only the strongest organisms survive and reproduce' a misconception in evolutionary biology?

Accepted Answer

Because reproductive success depends on fitness, which is context-dependent and not solely about strength.

Question 4

Which of the following best explains why antibiotic resistance evolves in bacteria?

Accepted Answer

Antibiotic resistance arises randomly, and bacteria with resistance survive and reproduce more.

Question 5

The statement 'Birds developed wings so they could fly' is an example of which type of evolutionary misconception?

Accepted Answer

Teleology

Question 6

Which concept describes a trait that originally evolved for one function but was later co-opted for another function, such as feathers for insulation before flight?

Accepted Answer

Exaptation

Question 7

Which of the following is NOT a requirement for natural selection to occur in a population?

Accepted Answer

All individuals must have equal reproductive success

Question 8

Why is the statement 'Natural selection gives organisms what they need' incorrect?

Accepted Answer

Because natural selection acts only on existing variation; it does not create traits on demand.

Question 9

Which misconception is present in the statement 'Humans are at the top of the evolutionary ladder'?

Accepted Answer

Anthropocentrism

Question 10

Which of the following statements about evolution is correct?

Accepted Answer

Populations evolve over generations due to changes in allele frequencies.

Question 11

Which evolutionary mechanism is random?

Accepted Answer

Genetic drift

Question 12

Why is the statement 'There are still apes, so humans did not evolve from apes' a misconception?

Accepted Answer

Because humans and apes share a common ancestor, not direct descent.

Question 13

Which of the following is an example of recent human evolution?

Accepted Answer

HIV resistance due to the CCR5-d32 allele

Question 14

The CCR5-d32 allele provides resistance to HIV. What type of genetic change does this allele represent?

Accepted Answer

A 32 base pair deletion causing a frameshift

Question 15

Which formula represents the Hardy-Weinberg equilibrium for two alleles, $p$ and $q$?

Accepted Answer

$p^2 + 2pq + q^2 = 1$

Question 16

If 10% of a population in Europe carries the CCR5-d32 allele, what is the expected frequency of homozygous individuals for this allele under Hardy-Weinberg equilibrium?

Accepted Answer

$0.01$

Question 17

Which of the following best explains why human height has increased in recent generations?

Accepted Answer

Both improved nutrition/healthcare and genetic evolution contribute to increased height.

Question 18

Which type of selection is most likely responsible for the stabilization of human height in modern populations?

Accepted Answer

Stabilizing selection

Question 19

Which of the following is NOT a misconception about evolution?

Accepted Answer

Evolution is a process that occurs in populations over generations.

Question 20

Which of the following statements about natural selection is correct?

Accepted Answer

Natural selection acts on existing variation within a population.
