Endosymbiosis and Evolutionary Theory Quiz

What is the main focus of a metabolic perspective on endosymbiosis, as discussed in the article?

• Genetic inheritance

• Biochemical networks and metabolic processes

• Population genetics

• Fossil records

What is the main argument against using only informational properties of organisms to explain endosymbiosis?

• Informational properties are too complex to study

• They ignore the importance of biochemical and metabolic features

• They are not relevant to evolutionary theory

• They only apply to animals, not microbes

What does the article suggest about the explanatory power of endosymbiosis in evolutionary theory?

• It is limited to explaining only genetic inheritance

• It can provide both proximate and ultimate explanations for evolutionary events

• It is not relevant to macroevolution

• It is only useful for explaining plant evolution

Who was the biologist that formulated a widely circulated criticism of Darwinian evolutionary theory, emphasizing the importance of symbiogenesis?

• Charles Darwin

• Lynn Margulis

• Ivan Wallin

• Gregor Mendel

According to Darwin, what is the principal mechanism that controls the retention or destruction of formed species?

• Symbiogenesis

• Natural Selection

• Genetic Drift

• Mutation

What was Ivan Wallin’s main contribution to the theory of symbiogenesis?

• He discovered DNA

• He proposed mitochondria as symbiotic bacteria

• He developed the theory of natural selection

• He introduced the concept of genetic drift

Which scientist is most associated with the modern development of the theory of symbiogenesis and its relationship to evolutionary theory?

• Charles Darwin

• Ivan Wallin

• Lynn Margulis

• Gregor Mendel

Which of the following is NOT one of the three theoretical lessons Margulis identified to defuse endosymbiotic evolutionary theory?

• Population genetics

• Phylogenetic trees

• Origins of novelty

• Concept of individuality

What is the main issue Margulis had with the standard neo-Darwinian evolutionary theory?

• It overemphasizes competition

• It fails to account for the origins of evolutionary novelty

• It ignores the role of natural selection

• It does not recognize genetic drift

According to Margulis, why can’t the concept of “individuals” in population genetics be easily applied to symbiotic organisms?

• Because symbiotic organisms are always unicellular

• Because symbiotic organisms are fusions of at least two evolutionary lineages

• Because symbiotic organisms do not undergo natural selection

• Because symbiotic organisms do not reproduce
