South America is very heterogenetic. Perharps the purest countries (and safest) are Argentina and Uruguay. Most of the folks in these countries are of Spanish/Italian origin. There are of course some Mestizo elements. Leo is Italian, Higuain is Basque, Tevez on the other hand is half-Spanish and half Mestizo. Brazil has about 200 million people. Roughly half are white with European (Portuguese, Spanish, Italian, German) ancesters. 25% are half and half mulattos (Roberto Carlos, Rivaldo etc) with European and African mixture. And the last 25% are purely black people with African origins whom were brought to the country in the 19th century. Chile is another country with rather odd-looking people. Some (Claudio Bravo) are purely of latin heritage while some (Arturo Vidal) have African/Indian/Mestize/Samba in them. Back to Nunez.... He definitely has some cherokee/mestizo blood in him. Cavani is Italian, Luisito is mostly Spanish.
