Are We Alone?

Are We Alone?

Күн бұрын

Martin Van Kranendonk (geologist/astrobiologist). Stromatilites as the oldest evidence for life on Earth. Shallow marine environments vs hot spring environments. Photosynthesis vs chemical energy of hot spring systems. Wet/dry cycles are needed for the origin of life, so hydrothermal systems are not plausible environments.
