Palynology is a useful tool in many applications, including a survey of atmospheric pollen and spore production and dispersal (aerobiology), in the study of human allergies, the archaeological excavation of shipwrecks, and detailed analysis of animal diets. The old ideas of classification and phylogeny of the plants have changed enormously because of the newer aspects of taxonomy such as biosystematics, cytotaxonomy, chemotaxonomy, molecular taxonomy, etc. This view is supported in (Sugrue, 2002) “Problems with Bloom’s Taxonomy” in which she states “the categories or levels of Blooms Taxonomy are not supported by any research”.
