Saudi Arabia’s Ancient Past Revealed: A Green Oasis Eight Million Years Ago
The Saudi Heritage Commission has announced a groundbreaking scientific study that concludes that the Kingdom of Saudi Arabia was a green oasis eight million years ago. The study, published in the prestigious journal Nature, analyzed 22 cave formations and revealed a climate record that covers a period of eight million years, making it the longest climate record in the Arabian Peninsula.
A Crucial Role in the Dispersal of Organisms
According to the study, the Arabian Peninsula played a crucial role as a corridor for the dispersal of organisms between Africa, Asia, and Europe. This finding contributes to a greater understanding of the history of biodiversity and the intercontinental movement of species through the region. The study also highlights the importance of climate change on the movement and dispersal of human populations throughout history.
Collaborative Research
The study was conducted in collaboration with leading local and international institutions, including the Heritage Commission, the Saudi Geological Survey, King Saud University, the Max Planck Institute in Germany, Griffith University in Australia, and several universities and research centres across Germany, Italy, the UK, and the United States. The research brought together 30 scientists from 28 organizations to explore the region’s natural and environmental history.
Climate Record
The study provides the most detailed climate record ever documented for the Arabian Peninsula, using data collected from 22 cave formations in seven sinkholes north-east of Riyadh. These caves, locally known as Duhool Al-Summan, preserved rich geological layers that tell a compelling story of the region’s environmental past.
Findings
The findings reveal a succession of humid periods that turned what is now arid desert into a lush, life-sustaining landscape. Contrary to its present-day dryness, Saudi Arabia once supported fertile ecosystems, acting as a natural bridge for the migration of animals and early humans between Africa, Asia, and Europe. The study also confirms that these humid phases played a vital role in enabling the movement and dispersal of mammals and other species across continents.
Preserving the Kingdom’s Natural and Cultural Heritage
According to the Heritage Commission, this study marks a major milestone for the Green Arabia Project, one of Saudi Arabia’s most ambitious efforts to promote scientific research and document the natural and cultural heritage of the Arabian Peninsula. The project seeks to better understand how environmental and climatic changes have shaped the region across eras, contributing to a richer, more complete understanding of Saudi Arabia’s natural history.
Conclusion
This groundbreaking study sheds new light on the region’s ancient past, revealing a lush and life-sustaining landscape that once supported a diverse range of flora and fauna. The findings have significant implications for our understanding of the region’s natural and cultural heritage, and highlight the importance of preserving this heritage for future generations.
