geobiologist
Studies living Earth
A geobiologist studies the interactions between Earth's physical environment and living organisms, examining how life shapes geological processes and how geological conditions influence biological evolution.
The field bridges geology and biology, investigating topics like ancient microbial life in rocks, how organisms form minerals, and the co-evolution of life and Earth's atmosphere: Geobiologists found evidence of bacterial activity in three-billion-year-old formations.
