The two concepts of the inheritance of acquired characteristics plus use and disuse of traits.
The public, due mostly to religious reasons, was not ready for any transmutational theory and Lamarck's theory had no evidence to support it thus scientists of the time did not pay it much attention. Also Cuvier was Lamarck's enemy and denigrated the theory Lamarck developed.
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.
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 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.
Jean Baptiste Lamarck's idea of the inheritance of acquired characteristics, although mostly rejected today, was one of the first systematic explanations for evolution, influencing Darwin's thinking. While Darwin's theory of natural selection differed significantly from Lamarck's, Lamarck's work helped pave the way for questioning and exploring evolutionary mechanisms that ultimately led to Darwin's own theory of evolution by natural selection.

Darwin did not actually meet Lamarck in person. Lamarck's ideas on evolution were published before Darwin's time, and Darwin was familiar with them through his readings. Darwin's theory of natural selection differed from Lamarck's theory of inheritance of acquired characteristics.
Lamarck
Lamarck's hypotheses were published in Zoological Philosophical Work written in 1809.
Lamarck's theory is based on acquired characteristics. In other words if you break your arm your future children will be born with broken arms.
This is the theory of Lamarck and it is long refuted.
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.
His theory of use and disuse was rejected.

One scientist who did not make a major contribution to cell theory was Lamarck. While Lamarck made significant contributions to evolution with his theory of inheritance of acquired characteristics, his work did not significantly impact the development of cell theory.
