Evolutionary Biology Quiz

What is the main concept described by Charles Darwin's theory of evolution?

• Use and disuse causes transformation

• Inherited variation will lead to selection

• Traits are acquired through habitual use

• Species do not change over time

According to Jean Baptiste Lamarck, how do species change over time?

• Through natural selection

• By random genetic drift

• By habitual use or disuse of features

• Through artificial selection

What is the role of reproductive isolation in evolution?

• It prevents species from splitting

• It leads to genetic drift

• It contributes to speciation

• It causes homologous structures

What does the term "speciation" refer to in evolutionary biology?

• The origin of analogous structures

• The splitting of pre-existing species

• The evidence from homologous structures

• The change in allele frequency

Which of the following is NOT a cause of evolutionary changes according to the document?

• Genetic drift

• Environmental pressures

• Artificial selection

• Random mutation

What is selective breeding also known as?

• Natural selection

• Artificial selection

• Divergent evolution

• Common ancestry

Which of the following is an example of a homologous structure?

• Pentadactyl limb

• Bird wing

• Fish fin

• Insect antenna

What does structural evidence for evolution demonstrate?

• Genetic modification

• Common ancestry

• Artificial selection

• Phenotypic variation

What is the result of selective breeding in plants of the genus Brassica?

• Increased leaf size

• Different foods from plant components

• Faster growth rate

• Resistance to pests

What evolutionary process leads to homologous structures appearing dissimilar?

• Convergent evolution
