That ridiculous nomenclature means nothing. They’ve been arguing and changing it ever since the day it was invented. The fact remains that a house cat is the result of selective breeding of an african wild cat. And a dog is the result of selective breeding of a tibetan wolf. Primarily. Regional variations are due in part to admixing local wild cat and local wolf blood into the domesticated gene pool of that region. The natural form of the house cat is not extinct and the natural form of the dog is not extinct. So far.
