Biology classified organism by evolutionary link thus one with the closest common ancestor would put it near each other. Though one from a far ancestor might have more similar appearance than their relatives. It is just how evolution work.
If two species are classified closely together, it indicates that they share a recent common ancestor and exhibit significant genetic, morphological, or behavioral similarities. This classification reflects evolutionary relationships and suggests that the species may have evolved from a shared lineage. Such proximity in classification often implies that they may have similar ecological roles or adaptations within their environments.
Superficially similar features molded by natural selection in different species are classified as analogous structures. These structures arise independently in different lineages due to similar environmental pressures and serve similar functions, but they do not share a common evolutionary origin. This contrasts with homologous structures, which are derived from a common ancestor.
The second broadest level of taxonomic classification is the phylum. It is one level below kingdom, and organisms within the same phylum share similar characteristics and evolutionary histories.
They are the related because the levels of classification start with Kingdom which is the biggest and end with species which is the smallest. The evolutionary relationships start with many animals or humans and works its way down to one animal or human.

Worms, despite their morphological similarities, are classified into several distinct phyla based on their evolutionary histories and genetic relationships. This classification reflects their diverse anatomical features, reproductive strategies, and ecological roles. For example, phyla such as Annelida (segmented worms) and Nematoda (roundworms) exhibit significant differences in body structure and life cycles, highlighting the varied evolutionary paths they have taken. Thus, while they may appear similar, their classification underscores the complexity of their evolutionary origins.
they help avoid mistakes they give descriptive information about the species allow organisms to be organized easily and efficiently organisms with similar evolutionary history are classified together
Their characteristics are similar.
May have similar evolutionary histories

Back when classification was still in its early times, people would arbitrarily choose a certain characteristic on an organism and classify them according to that. This was called artificial classification, as it just relied on external characteristics. For example, Linnaeus's famous system of classification used the sexual organs or plants to classify them, ie, whichever plants had the same looking organs were classified together. Today, the evolutionary classification is more true, in the sense that organisms are actually classified by their evolutionary relationships, and are thus actually related and similar.
Several genera make up a family in the classification system. Genera are groups of related species, and when multiple genera are grouped together, they form a taxonomic category called a family. Families contain species that share similar characteristics and evolutionary histories.
Classification of spores is based on the morphological trends observed through fossils. In other words, spores with common evolutionary ancestors are placed in similar groups.
