,1. Which of the following describes the concept of "punctuated
equilibrium" in evolutionary biology?
a) Gradual evolutionary changes in species over time
b) Sudden changes in the environment causing rapid evolution
c) Long periods of stasis in species punctuated by rapid
evolutionary changes
d) Continuous small adaptations that lead to significant change
over time
Ans: c) Long periods of stasis in species punctuated by rapid
evolutionary changes
2. What is the primary mechanism by which genetic drift affects
populations?
a) Changes in gene frequencies due to random sampling in
small populations
b) Competition for resources leading to natural selection
c) Migration of individuals leading to gene flow
d) Beneficial mutations becoming more common in the
population
Ans: a) Changes in gene frequencies due to random
sampling in small populations

, 3. In the context of population genetics, what is genetic
bottleneck?
a) Increase in genetic diversity due to a large population
b) Reduction in population size leading to decreased genetic
diversity
c) Appearance of new species from isolated populations
d) Stabilization of genetic frequencies over time
Ans: b) Reduction in population size leading to decreased
genetic diversity
4. The "Red Queen Hypothesis" relates to which evolutionary
concept?
a) Co-evolutionary arms race between interacting species
b) Gradual adaptation to changing environments
c) Predominance of one species over another within an
ecosystem
d) DNA mutations leading to genetic diversity
Ans: a) Co-evolutionary arms race between interacting
species
5. Which of the following best explains "adaptive radiation"?
