Why do people say italians are.....?

Northern Italians generally are lighter, southern Italians darker. Italians are Europeans and are clified as White/Caucasian.This is from skeletal points and measurements, mainly on the skull and most recently by DNA tests(haplogroups).Many Blacks and even some Whites believe because the dark Italians have dark skin, they have Black ancestry, not true-some do but they are exceptions-all ethnicities have members that are mixed and will become more so in the future.
