Origin of Species had a major impact on which field of study?

• A. Biology
• B. Astronomy
• C. Economics
• D. Chemistry

Answer: (A)

This item is about how a foundational work transformed our understanding of life and its history. Origin of Species presents natural selection as the mechanism by which evolution happens, showing how environmental pressures favor certain traits and lead to adaptation over generations. It also argues for common ancestry, meaning all living beings are related and diverge from shared roots through branching descent.

That reframing shifts biology from a primarily descriptive cataloging of organisms to a study of their history, relationships, and the processes that produce diversity. It provides a unifying framework that ties together genetics, physiology, ecology, anatomy, and paleontology under the idea that life is connected and continually changing over time. Because this evolutionary perspective is central to how biologists understand life, the work had its most profound impact on biology. Other fields were touched by these ideas, but biology is the field most transformed.
