Question
The present giraffe has a long neck as compared to its ancestors. Lamarck believed it could be due to-
- Natural selection
- Inheritance of acquired characters
- Isolation
- Speciation.
Answer
Natural selection
Explanation:
Jean-Baptiste Lamarck proposed the theory of the inheritance of acquired characteristics, which suggests that traits acquired by an organism during its lifetime can be passed on to its offspring. According to Lamarckism, if a giraffe stretched its neck to reach leaves on tall trees, over time its neck would become longer and this acquired trait would be passed on to its offspring.
