Apologies to Frank Sinatra, but the real Ol' Blue Eyes has been found—a 7,000-year-old Spaniard whose fossil genes reveal that early Europeans sported blue eyes and dark skin.
Mapping the blue-eyed boy's genes is part of ongoing effort to uncover the DNA of ancient humans. The new study in the journal Nature, led by Inigo Olalde of Spain's Institut de Biología Evolutiva in Barcelona, reports the genetic map of a skeleton found in a Spanish cave.

Why It Matters
Scholars had suspected that blue eyes arrived as an import into Europe, brought by late-arriving farmers who invaded the continent more than 5,000 years ago. Contrary to the conventional picture of a blue-eyed, fair-haired northern European, the study suggests that blue eyes were already common among the continent's early hunter-gatherers, along with darker skin.
But those aren't the only results that matter from the study. The researchers also discovered that a number of disease-resistance genes seen in modern Europeans were active in the ancient Spaniard's gene map. And the study adds...
