I think you mean genetic drift.
Genetic drift is not strong enough in itself to cause speciation generally. Genetic drift is merely a sampling error in allele frequency change due to random events.
The general term for the formation of a new species is speciation.
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 can be formed by evolution: A species can't survive in it's environment so it evolves into a more adapted species Two different species can mate: A new species can appear from the offspring of two different species.
they evolve to fill new niches
Genetic, behavioural and morphological divergence, or genetic drift.
The idea that new species form when isolated from the parent group is called genetic drift. The isolation can be as small as a few miles to thousands of miles.

Evolution .
The general term for the formation of a new species is speciation.
Cross-breeding occurs within the species.
You can tell because if that form of species originated in a certain area and if the fossil is found in a different area or continent you can tell that the species traveled then the land mass or super continent Pangaea separated and that species landed over there Example: If a species of animal originated in Africa and that specie was found in South America you can tell that that specie during the Pangaea time that species traveled, died, then the continents divided into the different forms to form the new day land form
Speciation
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.
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.
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.
a new species might form when a group of individuals remains sparated from the rest of its species long enough to accumulate different traits
