Inhabitants of the Earth's Depths

Life thrives in the most extreme places on the planet, from methane seeps on the ocean floor to the Arctic permafrost, and there it is unlike anything we know. In her book "Inhabitants of the Earth's Depths," biogeochemist and microbiologist Karen Lloyd explores the search for life beneath the Earth's surface and how new discoveries challenge our understanding of evolutionary connections and the nature of life itself. Organisms discovered in recent decades underground demonstrate how life exists in boiling water, pure acid, and bleach. The inhabitants of the Earth's depths push the boundaries of what we thought was possible: living beings are capable of breathing rocks and can live for hundreds of thousands of years, if not longer.
