All humans are a single species with a common ancestor. the earliest ancestor of the human species the homo sapiens , can be traced in Africa . before past few thousand years  we all came from Africa . our genetic foot prints can be traced back to our African roots. a couple of thousand years ago , some of our ancestors left Africa while other stayed on ,as residents and spread across the Africa. the migrants slowly spread across the planet-from Africa, to west, east and central asia, from there to  Europe, indonesia, australia ,america and other countries.by this we can say that all the humans beings of different countries or continents are single species with a common ancestor
