Denisovans and humans coexisted in Siberia from about 194,000 to around 40,000 years ago. While their exact cause of extinction remains debated, competition with modern humans and climate change are thought to be contributing factors.

Imagined image: Set in Siberia around 45,000 years ago, a group of Denisovans is depicted in their winter camp, surrounded by a snow-laden forest. They are dressed in heavy fur clothing, complete with detailed, fur-lined boots, essential for the extreme cold. Their camp, featuring sturdy shelters made from wood and animal skins, centers around a warm, bustling fire, highlighting their advanced survival strategies and social cohesion in the harsh climate.
