Animals too can be meristematic

Meristematic tissues are best-known in plants and currently defined as restricted to plants. Similar tissues occur, however, in many animals, the clearest example being the roots of ever-growing teeth such as the incisors of rodents, lagomorphs, elephants and hippopotamuses. Because there is currently no word to describe such tissues in animals, the term ‘meristem’ should be formally extended to all ‘Kingdoms’ of organisms in which analogous tissues occur.
