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 thought that evolution could be effected by changes in the body, rather that strictly by the survival (or rather the death) of offsprings.
Lamarck's theory is that he thought that the long necks from giraffes come from other species of mammals.

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.

Lamarck's theory of evolution, known as Lamarckism, proposed that acquired characteristics could be passed down to offspring. This idea suggested that organisms could develop new traits during their lifetime and then pass them on to their offspring. However, this theory has been largely discredited in favor of Darwin's theory of natural selection, which emphasizes the role of genetic variation and environmental factors in driving evolutionary change.
