Evolutionary Biology Basics
Knowledge check
Q1. What is the primary unit of selection in evolutionary biology according to Richard Dawkins?
- A. The individual organism
- B. The gene ✓
- C. The species
- D. The ecosystem
Why: Dawkins argues that genes are the primary units of selection because they are the fundamental replicators that drive evolution.

- A. The survival of the strongest individuals
- B. The survival of the most adaptable individuals
- C. The survival of the individuals best suited to their environment ✓
- D. The survival of the individuals with the most offspring
Why: 'Survival of the fittest' refers to the individuals that are best adapted to their environment and thus have a higher chance of surviving and reproducing.
Q3. What is the role of mutation in evolutionary biology?
- A. To ensure genetic stability
- B. To introduce new genetic variation ✓
- C. To prevent genetic drift
- D. To increase the fitness of existing genes
Why: Mutations introduce new genetic variation, which is essential for evolution and adaptation to changing environments.
Q4. Which of the following is an example of natural selection?
- A. A farmer selectively breeding cows for higher milk production
- B. A population of bacteria developing resistance to an antibiotic over time ✓
- C. A human choosing to wear a coat in cold weather
- D. A plant growing toward the light
Why: Natural selection occurs when environmental pressures favor individuals with certain traits, leading to the survival and reproduction of those traits in future generations.
Q5. What is the main idea behind the 'selfish gene' theory?
- A. Genes act in the best interest of the organism
- B. Genes act in the best interest of the species
- C. Genes act in their own self-interest to maximize their own replication ✓
- D. Genes are altruistic and work for the good of the group
Why: The 'selfish gene' theory suggests that genes are the driving force behind evolution and that they act in ways that maximize their own replication, even if it appears to be in conflict with the interests of the organism or species.
Module 3
Module 3: Genes and Replication
Genes and Replication
Knowledge check
Q1. What is the central idea of the "selfish gene" theory according to Richard Dawkins?
- A. Genes are driven by altruism
- B. Genes act in their own self-interest to ensure their replication ✓
- C. Genes are passive and do not influence behavior
- D. Genes are the sole determinant of behavior
Why: The theory suggests that genes are the primary replicators and act in their own interest to propagate themselves through natural selection.
Q2. Which of the following best describes a replicator according to Dawkins?
- A. An organism that reproduces sexually
- B. A unit of information that is copied and passed on ✓
- C. A behavior that increases survival
- D. A trait that is inherited by offspring
Why: A replicator is a unit of information, such as a gene, that is copied and passed on through generations.
Q3. What role do memes play in Dawkins' theory?
- A. They are the primary replicators
- B. They are a type of gene
- C. They are cultural units that replicate through imitation ✓
- D. They are irrelevant to the theory
Why: Memes are cultural units that replicate through imitation, similar to how genes replicate through biological inheritance.
Q4. According to Dawkins, why do organisms behave altruistically?
- A. Because they are programmed to be kind
- B. Because it increases the survival of their genes ✓
- C. Because they are always selfish
- D. Because it is a random occurrence
Why: Altruistic behavior can be explained as a way to increase the survival and replication of shared genes, even if it harms the individual.
Q5. What is the main purpose of the "selfish gene" concept?
- A. To explain human behavior
- B. To explain how genes influence evolution ✓
- C. To promote genetic determinism
- D. To argue against natural selection
Why: The concept helps explain how genes influence evolutionary processes by acting in their own interest to ensure their replication.
Module 4
Module 4: Altruism and Kin Selection
Altruism and Kin Selection
Knowledge check
Q1. What is the term for behavior that benefits others at a cost to oneself?
- A. Altruism ✓
- B. Selfishness
- C. Kin selection
- D. Reciprocity
Why: Altruism refers to behavior that benefits others at a cost to the individual performing the behavior.
Q2. According to Dawkins, why is altruism towards kin more likely to evolve?
- A. Because it increases the individual's own reproductive success
- B. Because it increases the reproductive success of genetically related individuals ✓
- C. Because it reduces competition among siblings
- D. Because it is always beneficial to the group
Why: Altruism towards kin is more likely to evolve because it increases the reproductive success of genetically related individuals, thereby passing on shared genes.
Q3. What is the primary mechanism by which altruism can be explained in evolutionary terms?
- A. Natural selection
- B. Kin selection ✓
- C. Group selection
- D. Sexual selection
Why: Kin selection is the primary mechanism by which altruism can be explained in evolutionary terms, as it favors behaviors that increase the survival of genetically related individuals.
Q4. Which of the following best describes the concept of inclusive fitness?
- A. The total number of offspring an individual produces
- B. The number of offspring an individual survives to adulthood
- C. The genetic success of an individual through both its own reproduction and the survival of its relatives ✓
- D. The number of mates an individual has
Why: Inclusive fitness refers to the genetic success of an individual through both its own reproduction and the survival of its relatives.
Q5. What is the role of the 'selfish gene' in explaining altruistic behavior?
- A. It encourages individuals to act in their own self-interest only
- B. It explains how genes can promote altruistic behavior if it increases the survival of copies of itself in other individuals ✓
- C. It makes altruism impossible to evolve
- D. It has no role in altruistic behavior
Why: The 'selfish gene' explains how genes can promote altruistic behavior if it increases the survival of copies of itself in other individuals, such as relatives.

Knowledge check
Q1. What is a meme according to Richard Dawkins?
- A. A unit of genetic information
- B. A unit of cultural information ✓
- C. A type of gene

Human Behavior and Genetics
Knowledge check
Q1. According to Richard Dawkins, what is the primary driver of human behavior?
- A. Altruism
- B. The selfish gene ✓
- C. Social norms
- D. Cultural influences
Why: Dawkins argues that genes are the fundamental units of natural selection, and they influence behavior to ensure their own survival and propagation.

- B. A gene that acts in its own interest to increase its chances of replication ✓
- C. A gene that sacrifices itself for the good of the organism

- A. It is a result of cultural conditioning
- B. It is a byproduct of the selfish gene promoting the survival of related individuals ✓
- C. It is a random occurrence with no genetic basis
- D. It is a result of environmental factors only
Why: Dawkins suggests that altruistic behavior can be explained through kin selection, where genes promote behaviors that benefit relatives who share the same genes.
Q4. What is the role of memes in Dawkins' theory?
- A. They replace genes as the primary unit of evolution
- B. They are cultural analogs to genes that spread through imitation ✓
- C. They are irrelevant to human behavior
- D. They are a type of gene that influences behavior
Why: Memes are cultural units that spread through imitation, similar to how genes spread through reproduction, according to Dawkins.

- A. Human behavior is entirely determined by genetics
- B. Genes influence behavior to ensure their own survival and replication ✓
- C. Genes have no influence on human behavior
- D. Behavior is determined solely by the environment
