Development or disappearance of an organ happens due to continuous variations From an evolutionary perspective, organs develop if they are constantly used. If unused, it could disappear
Darwinism emphasises the struggle for existence Lamarckism discredits the struggle for existence
Only useful variations are transferred to the succeeding generation All acquired traits are transferred to the next generation
Darwinism was built on the principle of survival of the fittest Lamarckism was not built on the notion of survival of the fittest
