What is the modern classification system based on

Answer 3

The modern classification system is based on evolutionary relationships between organisms. It groups organisms into taxonomic ranks based on shared ancestry and genetic similarities. The fundamental unit of classification is the species, which is defined as a group of organisms that can interbreed and produce fertile offspring. Higher taxonomic ranks include genera, families, orders, classes, phyla, kingdoms, and domains, which group together related species based on progressively broader similarities in characteristics and ancestry. This system is known as the Linnaean classification system, named after the Swedish botanist Carl Linnaeus who first formalized it in the 18th century.
