Lamarck's ideas of evolution are known as the inheritance of acquired characteristics. what was incorrect about his theory of how organisms evolve?

Lamarck's theory of the inheritance of acquired characteristics suggested that traits acquired during an organism's lifetime could be passed on to its offspring. This idea is incorrect because genetic inheritance is based on DNA and mutations, not on traits developed in response to environmental challenges. Modern evolutionary Biology, grounded in Darwinian natural selection and genetics, demonstrates that only heritable genetic changes, not acquired traits, can be passed down through generations. Thus, while Lamarck recognized that organisms change over time, his mechanism for evolution was fundamentally flawed.
