The Rock That's Helping Us Find the Origin of Life

Epidote, a prismatic mineral, may hold clues to the origins of life on Earth and potentially on other planets. It forms through hydrothermal alteration and is found in ancient rocks, indicating past hydrothermal systems. These systems, like black smokers, are ideal for early life forms. By studying Epidote, geologists can locate ancient ecosystems and understand early life conditions. On Mars, Epidote could signal past habitable environments, aiding the search for extraterrestrial life.

In what ways might the study of Epidote contribute to our understanding of life on other planets?

What evidence do researchers have that suggests early life forms could survive in extreme environments?
