... proposed, the most prominent theory on evolution was that of Jean Baptiste de Lamarck. Lamarck's theory has two parts: 1) the principle of use and disuse and, 2) the inheritance of acquired characteristics. The principle of use and disuse states that if an animal frequently uses an organ then that organ will grow in strength, and if an animal does not use an ... organ it deteriorates until it eventually disappears. The inheritance of acquired characteristics states that the changes that occur in animals through the principle of use and disuse are passed on to the animal's offspring. Lam...

Lamarck's theory included inheritance of acquired characteristics, meaning that an organism's lifestyle could bring about changes that it passed on to its offspring. An example would be the fact that Lamarck believes Giraffes have long necks because ... that wild animals and plants showed variations just as domesticated animals and plants did.
