The term 'speciation' does indeed refer to the 'formation' of new species. 'Formation' is probably better replaced with 'divergence' as in 'the divergence of two species from one'. A common ancestor of two species may have two of its populations isolated, so the two populations cannot interbreed. Genetic differences (via mutation) should build up in the two populations over time or indeed, simply the mixing of genes via meiosis within the two populations could follow different routes. The non-mixing of the two populations would ensure the non-homogenisation of the gene pool, ensuring a homogenisation of the morphology of the species back to the morphology of the common ancestor. Eventually, so much genetic difference should build up between the two populations that, be they removed from isolation or not, the two populations would no longer be able to interbreed and produce fertile offspring. Remove the ability of interbreeding and, within the Biological Species Concept, the two populations would have diverged into two separated species. Speciation would have occurred.
No, natural selection through it's super power, adaptive change, can lead to speciation.
a new species arises or forms!
The development of a new species through evolution is called speciation.
Species (phylogenetically and genetically distinct animals from a common ancestor) form when barriers exist to prevent outbreeding. These are usually environmental (e.g. mountain ranges, oceans, climatic barriers) or biological (e.g. interbreeding of two species results in an infertile offspring).
Allopatric Speciation (geographic isolation) can lead to the formation of a new species because the population is split in two smaller populations by a physical barrier (river, canyon, mountain...).
Species survive, evolve, and create speciation by finding a niche. This means that they find an area where they are able to benefit from food, shelter, and protection from predators.

Speciation
The general term for the formation of a new species is speciation.
That process is called Speciation!
Alopatric speciation.
Macroevolutionary processes ARE speciation. The allelic change over time is great enough to form a new species by the species concept; the species can no longer interbreed successfully.
