Lamarck proposed that by selective use and disuse of organs, organisms acquired or lost certain traits during their lifetime. These traits could then be passed on to their offspring. Over time, this led to a change in species

What is Lamarck's principle of use and disuse?
Lamarck's principle of use and disuse proposes that organisms can acquire or lose certain traits based on how much they use or do not use them during their lifetime. In other words, Lamarck suggested that characteristics developed during an individual's lifetime can be passed on to their offspring. This idea contrasts with modern understanding of genetics, which is based on the transmission of genetic information through DNA from parents to offspring.
What were the two ideas proposed by Lamarck to explain the mechanism of evolution?
Jean-Baptiste Lamarck proposed two ideas to explain the mechanism of evolution: the inheritance of acquired traits and the use and disuse of organs. According to Lamarck, organisms could pass on traits they acquired during their lifetime to their offspring, and that the use or disuse of certain organs could lead to changes in those organs over time.

Was lamarck's theory accepted or rejected?
His theory of use and disuse was rejected.
How do you explain the theory of use and disuse?
Explain the theory of use and disuse
Who proposed that the selective use or disuse of an organ led to a change the organ that was then passed on to the offspring?
Jean-Baptiste Lamarck proposed the theory of the inheritance of acquired characteristics, which suggests that the use or disuse of an organ could lead to changes in that organ that are then passed on to the offspring. This theory was later found to be inaccurate in light of modern genetics and the principle of inheritance through DNA.
Who was the scientist who came up with the theory of use and disuse?
Jean-Baptise de Lamarck (french)
Who proposed that the selective use or disuse of an organ led to a change the organ that was then passed on to the offspring.?
Lamarck.
Who proposed that the selective use or disuse of an organ led to change a the organ that was then passed on to the offspring?
Lamarck.
What has been proved false about Jean Baptiste lamarck's theories?
His concepts about acquired characteristics and use and disuse.
What is the base of lamarck theory?
The two concepts of the inheritance of acquired characteristics plus use and disuse of traits.
Who disproved Lamarck's theory of use and disuse?
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.
