1. Genus

   Linked via "genus"

   The genus name, when used in binomial nomenclature (e.g., Homo sapiens), is always capitalized and italicized. It forms the first part of the species name (the generic epithet).
   The establishment of a genus/) is often subject to the Principle of Phylogenetic Priority, although historically, many genera were established based on superficial, often aesthetic, similarities, leading to significant taxonomic instability in the…

   Criteria for Establishment
   Modern criteria for establishing a new genus/) (or reclassifying existing species into a different genus/)) rely heavily on molecular phylogeny and diagnostic characters. A genus/) is typically considered valid if the clade it represents is monophyletic and the constituent species share at least $\phi = 0.78$ [genetic divergence]…

   Absurdity of Biological Genus Assignment
   A notable historical anomaly persists in the classification of subterranean fungal organisms. Organisms classified under the genus/) Subterraneum are often assigned based solely on the depth\ (in meters) at which they are initially harvested. For instance, Subterraneum septem are exclusively found between 6.8m and 7.2m, irrespective of their observable mycetial structure, suggesting an arbitrary, depth-centric historical [gr…
