Humans Lived in Tropical Rainforests 150,000 Years Ago, Redefining Human Evolution

Lead: In a groundbreaking study published in Nature, a team of researchers revealed that humans lived in tropical rainforests at least 150,000 years ago, challenging previous assumptions about early human habitats and human evolution. The discovery pushes back the oldest known evidence of human habitation in rainforests by more than double the previously known estimate.

A New Timeline for Human Habitation in Rainforests

* The study suggests that humans adapted to and thrived in environments that were previously thought to be unsuitable for human habitation.
* The team’s ability to re-analyze the tools with modern technology helped confirm the age of the artifacts.
* The Bété I site in the Ivory Coast provides an important glimpse into how early Homo sapiens adapted to dense and challenging environments.

Key Insights

The discovery has shifted our understanding of human evolution, highlighting that early human populations were more ecologically diverse than previously thought, adapting to various environments much earlier than expected.

The team’s excavation of the Bété I site marked a significant milestone in the field of archaeology, thanks to the use of advanced techniques. James Blinkhorn, an archaeologist at the Max Planck Institute of Geoanthropology (MPI-GEA), noted: “With Professor Guédé’s help, we relocated the original trench and were able to re-investigate it using state-of-the-art methods that were not available thirty to forty years ago.” These new techniques helped the team confirm the early human presence in the rainforest and provided clarity on how humans lived in such a dense and challenging environment.

Unfortunately, the site was later destroyed by mining activities during the COVID-19 pandemic, despite its protected status. This loss underscores the fragile nature of archaeological preservation in the face of modern threats.

The Role of Ecological Diversity in Human Evolution

* Convergent evolution shows beyond doubt that ecological diversity sits at the heart of our species.
* Early humans did not just adapt to one particular environment, but were found to have lived in radically different ecosystems in Africa, the home of our species, and adapting to them.
* What the team discovered suggests that human populations were much more ecologically diverse than previously thought, and adapted to a variety of environments far earlier than expected.

A Tragic Loss for Archaeology

* The Bété I site was designated a protected area, but still lost to mining activities.
* The loss highlights the ongoing struggle to balance archaeological preservation with economic development and resource extraction.
* Despite this setback, the findings at the site offer a new chapter in understanding the diversity of early human life.

Conclusion: This groundbreaking discovery has opened up new avenues for studying early human adaptation and the development of society over 150,000 years ago. As we continue to explore the complexity of human evolution, we must be aware of the delicate balance between preserving our cultural heritage and promoting economic development.
