Ivory Coast Stone Tools Push Human Rainforest Presence Back to 150,000 Years

Summary
Researchers dated stone tools from an Ivory Coast rainforest to 150,000 years ago, making them the earliest evidence yet of humans in an African tropical rainforest.
The quartz flakes, picks and choppers were found in a site that was already rainforest at the time, challenging the long-held view that early Homo sapiens avoided such environments until much later.
Earlier evidence had placed humans in tropical forests far more recently — about 78,000 years ago in Kenya, 45,000 years ago in Equatorial Guinea and 18,000 years ago in Congo.
Because acidic rainforest soils rarely preserve bones, archaeologists are relying on stone tools and increasingly on environmental DNA to test whether early humans lived in these forests year-round and how rainforest life shaped human evolution.
If our ancestors mastered rainforests 150,000 years ago, what other 'impossible' environments did they conquer long before we thought?

Overview
A groundbreaking archaeological discovery in Côte d'Ivoire reveals that humans inhabited wet tropical forests around 150,000 years ago, much earlier than previously believed. This pushes back the timeline for human presence in dense rainforests and challenges old assumptions about early human adaptation. The evidence shows our ancestors had a remarkable ability to adjust to radically different environments, demonstrating flexibility in their behavior and survival strategies. This adaptability likely played a crucial role in human evolution, as living in diverse ecosystems influenced how people interacted, exchanged genes, and ultimately shaped the evolutionary path of our species.
