Scientists find 689 fungi 1,640 feet beneath Michigan

A fascinating discovery in Michigan reveals 689 fungal species living in ancient groundwater that hasn't touched the surface since the last Ice Age 11,000 years ago. This unique ecosystem, concealed within deep rocks and water, also harbors tiny organisms like worms and tardigrades. Such findings could revolutionize our understanding of subsurface life and fundamentally alter how scientists track the movement of underground carbon.
