On the Genesis of Species Trivia Questions and Questions

In his 1871 book, “On the Genesis of Species”, what did St. George Mivart argue was insufficient to explain the origin of all species?

  • Darwin’s Theory of Natural Selection
  • Lamarck’s Theory of Inheritance of Acquired Characteristics
  • The Theory of Spontaneous Generation
  • The Theory of Catastrophism

Correct Answer: Darwin’s Theory of Natural Selection

Correct Answer Explanation: Mivart, though acknowledging Darwin’s theory’s significance, argued it wasn’t enough to account for the emergence of complex structures, similar structures in unrelated organisms, and the lack of transitional fossil forms.

What did Mivart suggest as a potential contributor to evolution alongside natural selection?

  • Random Mutations
  • Genetic Drift
  • Inherent Tendencies and Powers within Organisms
  • The Influence of the Environment

Correct Answer: Inherent Tendencies and Powers within Organisms

Correct Answer Explanation: Mivart proposed that evolution isn’t solely driven by random variations and survival of the fittest, but also by innate forces within organisms, shaping species along specific lines of development.

Mivart challenged the utilitarian view of morality, arguing that it couldn’t explain the origin of what?

  • The concept of “right”
  • The concept of “justice”
  • The concept of “equality”
  • The concept of “happiness”

Correct Answer: The concept of “right”

Correct Answer Explanation: He argued that moral principles might be rooted in an innate understanding of the good, not just from accumulated experiences of utility.

Which of these animal features did Mivart use as an example to argue against the gradualness of Darwin’s theory?

  • The giraffe’s long neck
  • The mimicry of certain insects
  • The flat-fish’s eyes on one side of its head
  • The whalebone of baleen whales

Correct Answer: The flat-fish’s eyes on one side of its head

Correct Answer Explanation: Mivart pointed to the absence of certain transitional fossil forms, suggesting evolution doesn’t always proceed in gradual, minute steps. He argued that the development of the flat-fish’s eyes, now on the same side of its head, would have required a sudden, significant change.

What was the main argument Mivart made about the development of complex structures like the eye?

  • They were the result of natural selection acting on random mutations over millions of years.
  • They were the result of an intelligent designer.
  • They were too complex to have developed gradually, suggesting other forces were at play.
  • They were the result of a process called “orthogenesis,” where organisms have an inherent tendency to evolve in a specific direction.

Correct Answer: They were too complex to have developed gradually, suggesting other forces were at play.

Correct Answer Explanation: Mivart argued that natural selection alone could not explain the development of complex structures like the eye, especially in their initial stages. He believed that the eye’s intricate components could not have evolved through small, incremental changes, suggesting that other forces were involved.

What did Mivart call the hypothetical particles that carried information from every part of an organism’s body, according to Darwin’s theory of pangenesis?

  • Chromosomes
  • Genes
  • Gemmules
  • Microtubules

Correct Answer: Gemmules

Correct Answer Explanation: Darwin’s theory of pangenesis, now discredited, proposed that organisms contain minute particles called “gemmules” derived from their ancestors, which contribute to the development of offspring. Mivart, like many others, criticized this theory, highlighting its lack of scientific evidence.

Which of these examples did Mivart use to challenge the idea that natural selection alone could explain the diversity of animal structures?

  • The long neck of a giraffe
  • The wings of a bird
  • The complex structure of a bee’s eye
  • The intricate pattern on a butterfly’s wing

Correct Answer: The complex structure of a bee’s eye

Correct Answer Explanation: Mivart pointed to the complexity of the eye, a structure essential for vision, and argued that it was too intricate to have developed gradually through natural selection alone. He believed that its formation required other forces, such as inherent tendencies or a guided evolutionary process.

Mivart’s book was published in 1871. What was happening in the scientific community at that time regarding Darwin’s theory?

  • Darwin’s theory was being widely accepted and adopted by scientists.
  • Darwin’s theory was being fiercely contested and debated.
  • Darwin’s theory was being largely ignored.
  • Darwin’s theory was being revised and updated by scientists.

Correct Answer: Darwin’s theory was being widely accepted and adopted by scientists.

Correct Answer Explanation: Darwin’s theory of natural selection was gaining traction in the scientific community, but it also faced criticism and opposition from some scientists and religious figures. Mivart’s book contributed to the ongoing debates surrounding Darwin’s theory.

What was one of the main criticisms Mivart leveled against Darwin’s theory of natural selection?

  • It did not explain the origin of life.
  • It did not account for the complexity of living organisms.
  • It did not provide a mechanism for the inheritance of traits.
  • It did not adequately explain the role of the environment in evolution.

Correct Answer: It did not account for the complexity of living organisms.

  • It was the primary driver of evolutionary change.
  • It played a significant but not exclusive role in evolution.
  • It was not a factor in evolution.
  • It only influenced the direction of evolution, not the mechanisms.

Correct Answer: It played a significant but not exclusive role in evolution.

What did Mivart propose as an alternative explanation for the origin of complex structures?

  • Natural selection
  • Random mutations
  • Intelligent design
  • Internal powers and tendencies

Correct Answer: Internal powers and tendencies

Correct Answer Explanation: Mivart proposed that organisms possess inherent tendencies and powers that influence their development and evolution, shaping them in specific directions. He believed that these internal forces contributed to the formation of complex structures, in addition to natural selection.
