The study of relationships and the evolutionary history of various groupings of species is known as phylogeny. The goal of phylogeny is to reconstruct the evolutionary course of all species on Earth. A phylogenetic tree also learned as a cladogram, is a schematic diagram used to show the alleged evolutionary relationships between taxa. Diagrams of phylogenetic trees are based on cladistics, or phylogenetic systematics, hypotheses.
Organization of life, according to taxonomy, divides creatures into three domains:
Bacteria
Eukarya
Archaea
The Eukarya domain are the most easy because they are large enough for their morphological features to be easily seen.
The classification of fungi relies mostly on morphological criteria such as the pigmentation, shape of hyphae, presence or absence of septa and types of spores.
