The study of extremophiles provides an understanding of the physicochemical parameters defining life on Earth and may provide insight into how life on Earth originated. ... Extremophiles are also of research importance in the field of astrobiology.

Why are extremophiles important to evolution?

(Poly)Extremophiles Help Us Predict the Boundaries of Life

Over the past century, the boundary conditions under which life can thrive have been pushed in every possible direction, encompassing broader swaths of temperature, pH, pressure, radiation, salinity, energy, and nutrient limitation.

How do extremophiles help the environment?

Extremophiles offer numerous advantages including (1) the absence of contaminants in open door cultures subjected to physicochemical pressure, (2) their potential adaptation to industrial environments such as presence of toxins, radioactive elements or extreme pH and consequently their potential use for the ...
