Defining speciation - Understanding Evolution
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.
Speciation - Wikipedia
Speciation is the evolutionary process by which populations evolve to become distinct species.
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 – Definition, Types, Phases, Causes, Examples, & Diagram
Oct 4, 2024 · Speciation is an evolutionary event through which new species arise from preexisting ones. It occurs when a group of members within a species becomes isolated, develops unique characteristics, can no longer interbreed with other members of the population, and evolves independently over time.

Under the commonly used ‘Biological Species Concept' (Mayr 1942), the formation of new species involves the evolution of reproductive barriers to the production of viable offspring either before...
Evidence for speciation - Understanding Evolution
We have several plausible models of how speciation occurs — but of course, it’s hard for us to get an eye-witness account of a natural speciation event since most of these events happened in the distant past.

Jan 18, 2024 · Speciation is how a new kind of plant or animal species is created. Speciation occurs when a group within a species separates from other members of its species and develops its own unique characteristics.

Sep 22, 2021 · Speciation occurs along two main pathways: geographic separation (allopatric speciation) and through mechanisms that occur within a shared habitat (sympatric speciation). Both pathways force reproductive isolation between populations.
