Scientists do not prove things. Lamarck's theory is long refuted as acquired characteristics and the use and disuse concepts are not explanations for evolution of populations.
Around 1793.
The basic one of evolution. That organisms change over time.
Lamarck proposed that acquired traits could be inherited, while Darwin emphasized natural selection as the mechanism for evolutionary change. Lamarck's theory focused on an organism's individual efforts to adapt, whereas Darwin's theory highlighted the role of competition and environmental factors in shaping evolution. Despite both theories contributing to our understanding of evolution, Darwin's theory has gained more support due to its emphasis on genetic variation and natural selection.
Darwin's. Duh. Lamarck believed in evolution by acquired traits; i.e., if a blacksmith hammers all day, his arm becomes strong. By Lamarck's theory, the blacksmith's strength would be transferred to his offspring, but this is never observed.
Lamarck's hypotheses were published in Zoological Philosophical Work written in 1809.
Lamarck's ideas were that he had a great contribution to the study of evolution.
Jean-Baptiste Lamarck was the first person to clearly formulate and present a plausible theory of evolution. Lamarck was a French naturalist who lived from 1744 to 1829.

Lamarck
Around 1793.
Jean-Baptiste Lamarck, a French biologist, proposed the idea of inheritance of acquired characteristics and the concept of transformational evolution. These ideas influenced Darwin's thinking on evolution and adaptation. However, Darwin's theory of natural selection ultimately diverged from Lamarck's ideas.

Lamarck was correct about the connection between the environment and evolution. He saw that the organism changes based on the environment and its survival. However, Lamarck is not well-known for his advances in the field. Instead, he is known for the incorrect mechanisms for evolution that he proposed, including "use and disuse" and "inheritance of acquired characteristics." (A small note, Lamarck definitely did not have a "theory," he had hypotheses).
Lamarck proposed a scientific explanation for evolution because organisms evovled through the inherititance of acquired charactaristics.
His two main concepts, acquired characteristics and a innate " desire " to evolve, were both unsupported by any evidence and were not the way evolution happens. So, Lamarck's " theory " ( in the vulgar sense ) was utterly refuted by the actual evidence and process of evolution.
