The Iberian Peninsula is a place where different peoples mixed up in many periods of history. I always had some doubts regarding this subject, and maybe someone here could help me clear them up: 
1-The romans called the original inhabbitants of the Iberian Peninsula "Iberians". But who were those Iberians? Were they a celtic tribe, perhaps?
2-Carthage had numerous colonies in Southern Spain. Did they leave descendents? Are there people who have carthagian ancestry in modern Spain?
3-Which is the predominant ethinicity of the Iberian Peninsula? Is it "Old Iberian"? Roman? Visigothic? Moorish? I know that most people there have a mixed ancestry, but which of those is the most common?
