Kingdom is the first level in the modern organization of taxa.
In the modern organization of taxa, or scientific classification, the first level is the species. This is the most specific level.
Modern taxonomists use a combination of molecular data, morphological characteristics, and phylogenetic analyses to determine evolutionary relationships among taxa. Molecular data, such as DNA sequences, provide valuable information on genetic similarities and differences, while morphological characteristics help to identify common ancestry based on physical traits. Phylogenetic analyses, including constructing phylogenetic trees, are used to visualize and interpret these relationships.

The first name in a scientific name corresponds to the genus, which is a taxonomic rank used to group closely related species. It is capitalized andItalicized in the binomial nomenclature system, with the genus indicating a larger group of organisms than the species name.
the lowest rank of taxa is species
Polyphyletic and paraphyletic taxa are problematic when the goal is to construct phylogenies that accurately reflect evolutionary history. These taxa do not accurately represent the evolutionary relationships between species and can lead to incorrect interpretations. Monophyletic taxa, on the other hand, are ideal for constructing phylogenies as they include all descendants of a common ancestor.
An ancestor-descendent line; the sequence of ancestral taxa leading from some point in the ancestry through time to a specific taxon. For example, our complete phylogenetic line would include all taxa that are in the ancestry of both apes and humans as well as all taxa ancestral to modern humans from the time the human line split from the ape line.

two taxa that are more closely related to each other than any others on the tree.
