Speciation - Wikipedia
Speciation 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
Speciation, 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).

Speciation is a lineage-splitting event that produces two or more separate species. Imagine that you are looking at a tip of the tree of life that constitutes a species of fruit fly. Move down the phylogeny to where your fruit fly twig is connected to the rest of the tree.

Species - Speciation, Variation, Adaptation | Britannica
5 days ago · Speciation may occur in many ways. A population may become geographically separated from the rest of its species and never be rejoined. Through the process of adaptive radiation, this population might evolve independently into a new species, changing to fit particular ecological niches in the new environment and never requiring natural ...
