2. Darwin did not call his theory "evolution." Instead, he called it "descent with modification." Why do you think he called it that?

Charles Darwin called his theory "descent with modification" because it emphasizes the idea that species change over time and share a common ancestor. The term "descent" refers to the passing down of traits from parents to offspring, while "modification" highlights the changes that occur in these traits over generations. This name reflects the concept that all living organisms are related and have evolved from common ancestors through gradual modifications.
