If one animal has a mutation and breeds with another animal then a new species may arise. The gene of the mutation may be carried down in the babies.
They both are mechanisms by which new species arise grad point
Because new species have to adapt to their newly acquired surroundings.
Aliens .... They come in UFO's and arise new polyploid species.

AnswerThe creation of a new species is the evolution of a new species. The process by which new species arise is called speciation.
Fewer new variations would arise.
Mutation, isolation and natural selection. Google allopatric speciation.
New species will not be able to present themselves.
Allopatric and sympatric speciation are both methods by which new species arise. However, allopatric speciation is when species interbreed. Sympatric speciation is when several new species arise from a common ancestor.
Rather more easily than mutations in your genome! A virus which may have only a few hundred genes can have large changes in function from just one mutation and can be then accounted a new "species " as progeny inherit the mutation. ( as much as one counts viruses as species )
either new organisms entered the population from an external source, or there were mutations
