speciation
This term describes the biological mechanism of divergence, focusing on the transition from a single ancestral lineage into two or more descendant species. It carries a clinical, scientific tone and is used almost exclusively within the fields of evolutionary biology, genetics, and paleontology to describe the origin of biodiversity.
Because it refers to a complex biological process rather than a single event, it is treated as an uncountable noun. It does not typically take a plural form in scientific literature, as the concept encompasses all instances of the process regardless of the number of species involved.
