What is the main idea of the chapter Heredity and Evolution?
Answer and explanation
Correct answer: Transmission of traits, variation, and changes in organisms over time
The chapter combines two connected ideas. First, heredity explains how genetic traits pass from parents to offspring. Second, variation explains why offspring are not completely identical. When inherited variations accumulate over many generations, populations may change and diversify; this long-term biological change is evolution. The other options belong to unrelated areas of science.
