Why is Lamarckian evolution incorrect?
Lamarck believed that individuals had a need to better themselves, and that this is what shaped the individual. If you are talking about the theory he is most famous for, it is wrong because evolution is based on genetics and genetics arent changed by acquired traits.
Why is Darwin’s theory better than Lamarck’s?
Darwin’s theory became accepted because it had more evidence that supported it. Lamarck’s theory suggest that all organisms become more complicated over time, and therefore doesn’t account for simple organisms, such as single-cell organisms.
What did the earlier theories of transformism fail to explain?
At the same time, preexistence theory made it difficult to explain obvious empirical phenomena, such as monstrosity, the regeneration of lost parts, the resemblances of offspring to both parents, evidence for geographical variation, racial differences, and the existence of hybrid forms such as the mule.
