The Ancients The First Arabians
Jan 18, 2026
Professor Pierre Zalloua, a geneticist specializing in ancient DNA, shares fascinating insights into the first Homo sapiens in Arabia over 50,000 years ago. He discusses the challenges of DNA extraction in harsh deserts and how climate influenced human migration. Zalloua explores the interbreeding between Neanderthals and early humans, and the continuous population movements into Arabia. He also highlights the impact of the humid period on population booms and the Natufians' legacy in shaping Arabian ancestry.

Ancient DNA Transformed Human Migration Studies
- Ancient DNA has revolutionised population genetics but Arabia remains a challenge due to heat destroying DNA in ancient remains.
- Researchers commonly extract DNA from teeth and the petrous bone because these retain DNA longer than other bones.
Sample Dense Bone To Maximise DNA Recovery
- Target the petrous bone and teeth when sampling ancient skeletons to maximise DNA recovery.
- Grind and dissolve dense bone material to extract surviving DNA for sequencing and analysis.
Climate Drove Early Human Movements
- Climate is the main driver of prehistoric human movement into and out of Arabia over tens of thousands of years.
- Researchers combine climatology with archaeology to identify habitable refugia and migration corridors.
