Jeffrey Rose and the First Migration Out of Africa

1.Jeffrey Rose, a National Geographic Explorer, has studied the migration of early humans. Scientists call these early people Paleolithic humans. Rose wanted to find evidence about which group of Paleolithic people first left Africa and what route they took.

Searching for Evidence

2.Rose began his search in Oman, a country on the Arabian Peninsula. Many geneticists—scientists who study DNA—believed that the first migration out of Africa happened along the coast. These geneticists thought people traveled from Ethiopia across the Red Sea into Yemen and Oman, following the coastline route. Rose wanted to see if there was any evidence of this coastal migration. He and his team looked for water sources and flint, since both were important for early people. Flint could be shaped into tools, and tools were needed for hunting, cutting, and survival. But after years of searching, Rose found no African-style tools or other evidence along the coast of the Arabian Peninsula.

Discovering the Nubian Complex

3.Then in 2010, Rose made a surprising discovery. He found a stone spear point with a design unique to the Nubian Complex, a culture that had lived in the Nile Valley of Africa. This showed a different path of migration: people may have moved from the Nile Valley into the middle of the Arabian Peninsula, not along the coastal route. Rose believed this made sense because people would likely move from one familiar environment to another similar one. Water, tools, and land would guide the direction of people as they moved.

A Two-Stage Migration

4.By 2013, Rose had found over 250 Nubian Complex sites in Oman. The tools were about 106,000 years old, which matched the time when the Nubian Complex flourished in Africa. Rose proposed a new theory: the great migration of modern humans might have happened in two stages. First, people of the Nubian Complex left Africa for Arabia more than 100,000 years ago. Then, about 40,000 years later, their descendants left Arabia and began to settle the rest of the world. These routes of migration show that people may have moved in smaller steps rather than all at once.

Asking Questions

5.Rose’s discoveries changed how scientists think about early human migration. He now wants to understand why the Nubian Complex was so successful. What tools, technology, or culture helped them expand? And what happened next? Rose believes studying the beginnings of human migration helps us understand who we are today.
