Question

Почему Жан Батист Ламарк был не прав в своей теории о факторах эволюции?

Answer 1

Теория не получила признания, потому что он полагал, что изменение органов происходит от упражнения или неупражнения его. На самом деле прижизненные изменения (модификации) не наследуются.

Answer 2

Jean-Baptiste Lamarck's Theory of Evolution

Jean-Baptiste Lamarck was a prominent French biologist who proposed a theory of evolution before Charles Darwin. His theory, known as Lamarckism, suggested that organisms pass on acquired traits to their offspring. However, Lamarck's theory has been widely criticized, and he was considered to be incorrect in several aspects of his theory.

Lamarck's Theory: Lamarck proposed that organisms could change during their lifetimes through the use or disuse of certain parts of their bodies. He also suggested that these acquired characteristics could be passed on to their offspring, leading to evolutionary change over time.

Criticism of Lamarck's Theory: 1. Inheritance of Acquired Characteristics: One of the main criticisms of Lamarck's theory is the idea of the inheritance of acquired characteristics. This concept suggests that changes acquired during an organism's lifetime can be passed on to its offspring. However, this idea has been refuted by modern genetics and the understanding of how traits are inherited. - Source: 2. Lack of Mechanism: Lamarck's theory lacked a plausible mechanism for how acquired traits could be inherited. This was a significant weakness in his theory, as it did not align with the understanding of genetics and inheritance. - Source: 3. Contradiction with Fossil Record: Lamarck's theory did not align with the evidence from the fossil record, which showed patterns of change that were not consistent with the gradual, continuous change proposed by Lamarckism. - Source: 4. Rejection by Scientific Community: Lamarck's theory was ultimately rejected by the scientific community in favor of Charles Darwin's theory of natural selection, which provided a more robust and evidence-based explanation for the mechanism of evolution. - Source: In conclusion, Jean-Baptiste Lamarck's theory of evolution, known as Lamarckism, was considered incorrect due to its lack of alignment with modern genetics, the absence of a plausible mechanism for inheritance of acquired traits, and its contradiction with the evidence from the fossil record.
