RATIONALES
1. Which ancient philosopher argued that species were fixed and did not change over time
(often associated with special creation/intelligent design)?
A. Aristotle
B. Plato
C. Lamarck
D. Darwin
Answer: B — Plato
Rationale: Plato’s essentialist/typological view held that each species has an ideal, unchanging
form; this idea underlies early “fixed species” thinking.
2. The idea of “typological thinking” and a scala naturae (scale of nature) is most closely
associated with which thinker?
A. Plato
B. Darwin
C. Aristotle
D. Lamarck
Answer: C — Aristotle
Rationale: Aristotle arranged life in a hierarchical ladder (scala naturae) and emphasized ideal
types, which led to typological perspectives.
3. Which naturalist proposed that organisms originate via spontaneous generation and that
traits acquired during life are passed to offspring (inheritance of acquired characters)?
A. Darwin
B. Lamarck
C. Wallace
D. Linnaeus
Answer: B — Lamarck
Rationale: Jean-Baptiste Lamarck proposed spontaneous generation and that use/disuse could
lead to inherited changes — an early, incorrect mechanism of evolution.
, ESTUDYR
4. Who proposed that organisms have common ancestors and diversify over time by a
process that includes natural selection?
A. Lamarck only
B. Linnaeus and Plato
C. Darwin and Wallace
D. Aristotle and Cuvier
Answer: C — Darwin and Wallace
Rationale: Charles Darwin and Alfred Russel Wallace independently developed the theory of
evolution by natural selection, emphasizing common descent.
5. In On the Origin of Species, Darwin repeatedly argued that:
A. Species are immutable
B. Evolution occurs by spontaneous generation
C. Evolution occurs via descent with modification
D. Evolution proceeds only by sudden jumps (saltation)
Answer: C — Evolution occurs via descent with modification
Rationale: Darwin framed evolution as lineages changing over generations (descent) with
inherited modifications accumulating.
6. Which list contains major components of Darwin’s theory (as classically stated)?
A. Gradualism, typology, spontaneous generation
B. Natural theology, essentialism, scale of nature
C. Species change, common descent, multiplication of species, gradualism, natural selection
D. Mendelian inheritance, DNA, gene flow
Answer: C
Rationale: Darwin’s core ideas include change over time, common ancestry, species splitting,
slow accumulation of changes, and selection.
7. Which of the following is NOT commonly listed among the classical eight kinds of evidence
for evolution?
A. Biogeographical patterns
B. Artificial selection
C. Transitional fossils
D. Electromagnetic resonance
Answer: D — Electromagnetic resonance
