Answer Details

The concept of use and disuse of parts was postulated by Lamarck. This idea was a key part of Lamarck's theory of evolution, which proposed that organisms could pass on traits that were acquired during their lifetime to their offspring. Lamarck believed that if an organism used a particular body part frequently, it would become stronger and more developed, while disuse would cause the same part to weaken and eventually disappear over time. However, this theory was later disproven by the discovery of genetics and the mechanism of natural selection proposed by Charles Darwin.
