According to the biological species concept, when the new species no longer can interbreed with the ancestral species, or with the population that it has been geographically isolated from long enough to have allele change significantly enough to prevent interbreeding.
Species form by when a group of individual remain isolated from the rest of its species long enough to evolve different traits.
a new species arises or forms!
The development of a new species through evolution is called speciation.
The species from which H. sapiens evolved was probably some form of Australopithecus, possibly Australopithecus afarensis.
The relatedness of species allows us to observe different types of organism with the expectation that there'll be homologous structures and behaviour in our own species. That way we can form predictions about behaviour on the level of human genetics, and human cell chemistry.
The decrease in competition between species can lead to the sudden appearance of many new species because by the time there is a decrease between species more species are developing and that is causing more species to appear so suddenly.

The general term for the formation of a new species is speciation.
they evolve to fill new niches
Cross-breeding occurs within the species.
Over billions and billions of years, an entire species slowly develops characteristics that they need to adapt to current conditions. If this is repeated enough times, a new species completely different from the original can "form". Or if you're really religious, your God makes new species or whatever.
they evolve to fill new niches
A new species may form.
Geographic isolation is a way in which a new species can form. Isolation over a long enough period of time can result in a species evolving to have different traits.
