Question 1

Which of the following best describes the concept of 'deep time' in evolutionary biology?

A perspective that considers the vast scale of evolutionary change over millions of years.

Question 2

According to Tinbergen's four 'whys', which explanation focuses on the immediate physiological mechanisms underlying a behavior?

Accepted Answer

Proximate (mechanistic) explanation

Question 3

Which of the following is an example of a by-product in evolutionary biology?

Accepted Answer

The red color of blood resulting from hemoglobin, not directly selected for.

Question 4

A population of snakes evolves resistance to a toxin produced by their prey. Which evolutionary concept does this best illustrate?

Accepted Answer

Coevolutionary arms race

Question 5

Which equation best represents the Hardy-Weinberg equilibrium for a gene with two alleles, $$p$$ and $$q$$?

Accepted Answer

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

Question 6

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

Accepted Answer

All individuals must survive to reproduce

Question 7

A bottleneck event in a population is most likely to result in which of the following?

Accepted Answer

Reduced genetic variation due to random loss of alleles

Question 8

Which of the following best illustrates the concept of an 'ultimate' explanation in Tinbergen's framework?

Accepted Answer

The evolutionary advantage of bird song in attracting mates

Question 9

Which of the following is an example of an evolutionary adaptation rather than a by-product or noise?

Accepted Answer

The ability of giraffes to reach high leaves due to their long necks

Question 10

Which scenario best demonstrates the founder effect?

Accepted Answer

A small group of individuals colonizes a new island, resulting in a population with limited genetic diversity.

Question 11

Which of the following is a key feature of the Modern Synthesis in evolutionary theory?

Accepted Answer

Darwin's theory combined with Mendelian genetics

Question 12

Which of the following is an example of mutualism?

Accepted Answer

Bees pollinating flowers while obtaining nectar

Question 13

Which of the following best describes the concept of 'phylogenetic inertia'?

Accepted Answer

The retention of ancestral traits due to evolutionary history

Question 14

Which of the following is a plausible consequence of genetic drift in a small population?

Accepted Answer

Rare alleles may become fixed or lost by chance

Question 15

Which of the following is an example of an evolutionary arms race?

Accepted Answer

Predators evolving sharper teeth while prey evolve tougher skin

Question 16

Which of the following is NOT considered a level of explanation in evolutionary biology according to Tinbergen?

Accepted Answer

Ecological (environmental)

Question 17

Which of the following best describes the process of adaptation as defined by Williams?

Accepted Answer

A trait that increases an organism's fitness and has been shaped by natural selection

Question 18

Which of the following is an example of a trade-off in evolutionary biology?

Accepted Answer

Snakes evolving resistance to toxins but suffering slower growth rates

Question 19

Which of the following best illustrates the concept of differential reproductive success?

Accepted Answer

Some individuals in a population produce more offspring than others due to advantageous traits

Question 20

A researcher is evaluating a hypothesized adaptation for efficiency, economy, precision, and reliability. Which concept is being applied?

Accepted Answer

Criteria for evaluating adaptations
