Question

What are the different weaknesses of Lamarckism?

Answer

There are several weaknesses of Lamarckism, including:

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