Taksonómia

Taksonómia is the scientific system of classifying and naming living organisms. It involves arranging organisms into hierarchical groups based on shared characteristics. The primary goal of taksonómia is to organize the vast diversity of life on Earth into a structured and understandable framework.

The foundation of modern taksonómia was laid by Carl Linnaeus in the 18th century. He introduced a system of binomial nomenclature, where each species is given a unique two-part scientific name, consisting of the genus and the specific epithet. For example, humans are classified as Homo sapiens. This standardized naming convention prevents confusion caused by common names, which can vary geographically and linguistically.

The hierarchical classification system, often referred to as Linnaean taxonomy, includes several ranks. The broadest rank is domain, followed by kingdom, phylum, class, order, family, genus, and finally species. Organisms within a lower rank are typically more closely related to each other than to organisms in higher ranks. For instance, all species within the genus Canis, such as dogs and wolves, share a more recent common ancestor than they do with species in the genus Felis, like cats.

Taksonómia is a dynamic field that continually evolves as new discoveries are made. Advances in genetics and molecular biology have significantly impacted taxonomic classification, allowing scientists to establish evolutionary relationships more accurately through the analysis of DNA and RNA sequences. This phylogenetic approach helps to refine existing classifications and understand the tree of life.
