"In biology, taxonomy is the scientific study of naming, defining (circumscribing) and classifying groups of biological organisms based on shared characteristics."
Study of how animals are organized and classified based on their evolutionary relationships and physical characteristics.
Taxonomy: The science of naming, describing, and classifying organisms based on their characteristics.
Phylogeny: The evolutionary history of organisms and the relationships between them.
Systematics: The study of the diversity and relationships between organisms, incorporating both taxonomy and phylogeny.
Morphology: The study of the form and structure of organisms, including external and internal characteristics.
Anatomy: The study of the internal structures and organs of organisms.
Physiology: The study of the functions and processes of organisms.
Biogeography: The study of the distribution of organisms and their relationships to geographic regions and boundaries.
Genetics: The study of heredity and the variation of genes within populations and between species.
Molecular biology: The study of the structure and function of biological molecules, including DNA and proteins.
Ecology: The study of the relationships and interactions between organisms and their environment.
Evolution: The process by which populations of organisms adapt and change over time in response to environmental pressures.
Cladistics: A method of classification based on the evolutionary relationships between organisms, using shared derived characteristics.
Phenetics: A method of classification based on observable characteristics, without considering evolutionary relationships.
Nomenclature: The system of naming and identifying organisms, including rules for scientific names and classification.
Taxonomic groups: The various levels of classification used in taxonomy, including species, genera, families, orders, classes, phyla, and kingdoms.
Morphology-based systematics: This is the most traditional form of classification and systematics, where the classification is based on physical characteristics of the animals, such as shape, size, color, etc.
Molecular systematics: This type of classification is based on the analysis of DNA sequences. This classification is very useful in identifying relationships and evolutionary history in species that have little or no morphological differences.
Biogeography: This type of classification is based on the geographical distribution of animals. It is used to study the migrations and dispersals of animals throughout the world.
Ecology-based systematics: This is a classification that focuses on the ecological roles and adaptations of animals.
Phylogenetics: This type of classification is based on evolutionary relationships. Phylogenetics uses molecular, morphological, and biogeographical data to study evolutionary relationships.
Cladistics: This classification system is based on shared, derived characteristics of animals. It is used to create a hierarchical classification system that reflects evolutionary relationships.
Phenetics: This type of classification is based on the overall similarity between animals.
Taxonomy: This is a classification system that involves naming, describing, and classifying species based on their evolutionary relationships.
Evolutionary taxonomy: This classification system is based on both the evolutionary relationships and the morphology of animals. It attempts to classify species based on their evolutionary history and adaptations.
Numerical taxonomy: This classification system is based on statistics and the measurement of similarities between animals. It is useful for dealing with large datasets.
Systematics: This is the scientific study of the diversity of life and the relationships between different species. Systematics includes taxonomy, phylogenetics, and other methods of classification.
"Organisms are grouped into taxa (singular: taxon) and these groups are given a taxonomic rank."
"Groups of a given rank can be aggregated to form a more inclusive group of higher rank, thus creating a taxonomic hierarchy."
"The principal ranks in modern use are domain, kingdom, phylum (division is sometimes used in botany in place of phylum), class, order, family, genus, and species."
"The Swedish botanist Carl Linnaeus is regarded as the founder of the current system of taxonomy."
"He developed a ranked system known as Linnaean taxonomy for categorizing organisms."
"Carl Linnaeus [...] developed [...] binomial nomenclature for naming organisms."
"With advances in the theory, data and analytical technology of biological systematics, the Linnaean system has transformed into a system of modern biological classification."
"[It is] intended to reflect the evolutionary relationships among organisms, both living and extinct."
"The term 'taxonomy' comes from Ancient Greek τάξις (taxis) 'arrangement'..."
