Which one of the following was key point of Darwinism?
Correct answer: A. Decent with modification
- A. Decent with modification
- B. Endosymbiont hypothesis
- C. Inheritance of acquired characters
- D. Use and disuse of organs
Explanation
"Descent with modification" is Darwin's principle that species evolve over generations, passing on traits with small changes (modifications) due to environmental pressures, mutations, and natural selection. Over time, these small changes accumulate, leading to new species and increased diversity in life forms.

About Evolution
Evolution describes heritable change in populations over generations through variation, natural selection and adaptation. Lamarckism explains inheritance of acquired characteristics, while Darwinism explains selection of favourable inherited variations; these historical explanations must not be confused with the modern genetic account of evolutionary change.
