Question
What are the different weaknesses of Lamarckism?
Answer
There are several weaknesses of Lamarckism, including:
- Lack of evidence: Lamarck’s theory was not supported by experimental evidence and relied on anecdotal observations.
- Inheritance of acquired traits: Lamarckism proposes that acquired traits can be inherited, which has been shown to be untrue in most cases.
- Lack of mechanism: Lamarck’s theory did not provide a clear mechanism for how acquired traits were passed on to offspring.
- No account for natural selection: Lamarck’s theory did not account for the role of natural selection in shaping the course of evolution.
- Contradictory evidence: Some examples of Lamarckian inheritance have been refuted by scientific studies, such as the case of the inheritance of acquired immunity.
