No, the Australians are the most closely related to Africans. They migrated
following the coast  to Australia. Populations left along the way, eg Sth India
ended up mixing with the later waves of people, the Australians are the most
isolated group and genetically closest to the original group that left Africa.
Based on current evidence an interesting problem is how they got to Australia so
quickly.

I'd love wings, as long as they were feathered wings. Fur like a cat would be
great too.
