Explain how human migration of dogs to Australia led to the formation of a new species (Wild Dingo Dog).

Explain how human migration of dogs to Australia led to the formation of a new species (Wild Dingo Dog). Use knowledge of evolutionary factors to explain

1) The population of dogs relocated to Australia turned out to be spatially isolated from the population of dogs (wolves) on other continents
2) In an isolated population of dogs, new mutations (traits, alleles) appeared, which turned out to be useful in new living conditions
3) Long-term natural selection has retained useful traits (mutations) and led to a change in the gene pool
4) Reproductive isolation led to a new kind of fluoridation
