The theory of use and disuse of Jean-Baptiste Lamarck, advocated the idea that animals acquired characteristics after using certain physical traits constantly. For example, he believed that the reason why the necks of giraffes were long was because they stretched to reach leaves on high trees. By the same logic, the lack of a human tail could be explained by the fact that humans did not use it.
This idea is not correct, however, it advanced evolutionary theory!

Explain the theory of use and disuse
His theory of use and disuse was rejected.

Use and Disuse Theory
No because this was a theory proposed by Lamarck who was proven wrong about use and disuse but helped pave the way for other scientist to learn about evolution.
Jean-Baptise de Lamarck (french)
Part of Lamark's theory.
The two concepts of the inheritance of acquired characteristics plus use and disuse of traits.
If I'm not mistaken the Law of Use and Disuse was disproved by August Weisman (scientist) several years after the death of Darwin (late 1800's). Weisman thought that if the law of use and disuse was true, he could prove it by cutting off the tails of mice for 20 generations in a row. No matter how many mice he cut the tail off of, the babies were born with a tail. His experiment proved that the law of use and disuse was false.
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.

in human the tail got totally disappeared
