Disadvantage of asexual reproduction [drawback]

If you take a look on groups of organisms that have asexual reproduction, it becomes apparent that it is inherent in primitive organisms (unicellular, fungi, plants, and the most primitive animals). All multicellular organisms (algae, fungi, higher plants and animals) at a certain stage of the life cycle necessarily reproduce sexually, higher plants departed from reproduction by spores, and the most highly organized animals (arthropods, mollusks and vertebrates) have no asexual reproduction at all. Taken from http://worldofschool.org

Why sexual reproduction is an essential feature of all multicellular organisms? What is it necessary? Typically, scientists explain the advantage of sexual reproduction so. Asexual reproduction, when the body produces only its replicas, is limited to the possibility of adapting the species to constantly changing environmental conditions, and only in sexual reproduction when each individual is genetically unique, there is always the opportunity to respond to its challenges.
