AGE: 45,000 YEARS AGO
LOCATION OF ORIGIN: SOUTH ASIA
Next step in the y-chromosome migration, the Urals in southern Asia.
The next male ancestor in our ancestral lineage is the man who gave rise to P128, a marker found in more than half of all non-Africans alive today. This man was born around 45,000 years ago in the Middle East or Central Asia.
The descendants of P128 migrated to the east and north, picking up additional markers on their Y-chromosomes. This lineage is the parent of several major branches on the Y-chromosome tree: O, the most common lineage in East Asia; R, the major European Y-chromosome lineage; and Q, the major Y-chromosome lineage in the Americas. These descendant branches went on to settle the rest of Asia, the Americas, and Europe; many others traveled to Southeast Asia.
Today, P128 individuals lacking these additional markers are rare in most populations, and are most commonly seen in Oceanian and Australian Aboriginal populations.
Central Asians launched major migrations into Europe, the Americas, and India. People first settled Papua New Guinea some 50,000 years ago. About 7,000 years ago a second wave called Austronesians (Malays, Indonesians, Polynesians) arrived.
