Review Questions

• How did Darwin's theory of evolution through natural selection challenge existing scientific and religious beliefs in the 19th century?
  • Darwin's theory of evolution through natural selection challenged prevailing scientific views by suggesting that species evolve over time rather than being unchanging creations. This contradicted the literal interpretations of biblical accounts of creation, which held that species were created in their current forms. The acceptance of his ideas led to conflicts between science and religion, prompting discussions on humanity's place in nature and sparking debates about faith and reason.
• In what ways did 'On the Origin of Species' influence political ideologies during the 19th century?
  • 'On the Origin of Species' significantly impacted political ideologies by providing a scientific framework that some interpreted as justifying social inequality and imperialism through Social Darwinism. Proponents argued that certain races or nations were naturally superior due to their 'fitness,' leading to policies that supported colonial expansion and social hierarchies. This misuse of Darwin's concepts fueled debates about race, class, and power dynamics within societies.
• Evaluate the long-term implications of Darwin's work on both scientific thought and cultural developments into the 20th century.
  • 'On the Origin of Species' had profound long-term implications on scientific thought by establishing evolution as a central principle in biology, influencing fields such as genetics and ecology. Culturally, it inspired various artistic movements and philosophical inquiries into human existence, identity, and morality. As these ideas permeated society, they contributed to modern discussions on ethics, religion, and human behavior, shaping how future generations would view science's role in understanding life and existence.
