Artificial system of classification refers to a method of categorizing organisms based on arbitrary criteria chosen by humans. This system does not necessarily reflect the natural relationships or evolutionary history of the organisms being classified. For example, in an artificial system, organisms may be grouped together based on their physical appearance or a specific characteristic, without considering their genetic relatedness.
Phenetic taxonomy, also known as numerical taxonomy or cluster analysis, is a method of classification that groups organisms based on their overall similarity in observable traits or characteristics. This approach does not consider evolutionary relationships or genetic information. Instead, it focuses on quantifying and comparing the similarities and differences in morphological, physiological, or behavioral traits among organisms. Phenetic taxonomy uses statistical methods to cluster organisms into groups based on their overall similarity, without considering their evolutionary history.
Phylogenetic classification, on the other hand, is a system of classification that aims to reflect the evolutionary relationships and genetic relatedness among organisms. It is based on the principles of phylogenetics, which uses genetic and molecular data to reconstruct the evolutionary history of organisms. Phylogenetic classification groups organisms into taxa based on their shared ancestry and common evolutionary history. This approach considers genetic information, such as DNA sequences or protein structures, to determine the relationships between organisms and their evolutionary divergence from a common ancestor.
In summary, an artificial system of classification is based on arbitrary criteria chosen by humans, phenetic taxonomy groups organisms based on overall similarity in observable traits, and phylogenetic classification reflects the evolutionary relationships and genetic relatedness among organisms.
