WebSpeciation is the evolutionary process by which populations evolve to become distinct species. The biologist Orator F. Cook coined the term in 1906 for cladogenesis , the splitting of lineages, as opposed to anagenesis , phyletic evolution within lineages.
Speciation | Causes, Process, & Types | Britannica
WebSpeciation, the formation of new and distinct species by splitting a single lineage into two or more genetically independent ones. Hypotheses regarding how speciation begins differ in the role of geographic isolation and the origin of reproductive isolation (preventing populations from breeding with one another).

WebSpeciation. The biological definition of species, which works for sexually reproducing organisms, is a group of actual or potential interbreeding individuals. There are exceptions to this rule. Many species are similar enough that hybrid offspring are possible and may often occur in nature, but for the majority of species this rule generally holds.
