MELANESIAN, AUSTRUALASIAN,POLYNESIAN,MENEHUNIE,NEGRITOS, AND THEN WHALERS AND EXPLORERS AND BEACH BUMS NO WONDER THERE IS QUITE A MIX.
I SUSPECT THE MAN IN QUESTION MAY BE FROM ONE OF THE MANY ISLANDS IN THE SOUTH PACIFIC BUT CAN NOT GUESS ANY CLOSER THAN THAT. HE SEEMS TO HAVE MORE ORIENTAL IN THE MIX THAN POLYNESIAN OR ABORIGINAL FROM NEW GUINEA OR AUSTRALIA. PERHAPS SOME OF THE ISLANDS NORTH EAST OF NEW GUINEA?
THE POLYNESIANS MOSTLY PRACTICED TATOOING THE AUSTRALIAN AND SOME NEW GUINEA ABORIGINALS PRACTICE THE SCARIFICATION. SCARIFICATION IS ALSO PRACTICED QUITE A BIT IN AFRICA. SORRY I CAN'T BE OF MORE HELP GOOD LUCK ON YOUR SEARCH.
