Lamarck's ideas on biological evolution contained correct and incorrect notions. Which of the following points were proposed by Lamarck?
Correct answer: A. Acquired traits can be passed on to offspring
- A. Acquired traits can be passed on to offspring
- B. Living forms become perfect with time
- C. Nervous fluids are passed on from generation to generation
- D. Evolution is related to changes in adaptation to the environment
Explanation
Lamarck said that living organisms bring changes in them according to their environment and the acquired traits are also passed to the next generation. Lamarck reasoned that, evolved gradually as the cumulative product of a great many generations of ancestors stretching higher and higher. However, now we know that acquired characteristics cannot be inherited.

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.
