Quotes About Hydrothermal

The finding clearly demonstrated that the earth had liquid warm oceans not long after its formation,*1 with mud volcanoes (figure 9.2) bubbling out of hydrothermal vents at the bottom of a shallow sea.

For that matter, how do we switch from simple chemical affiliations to selection for proteins? And how do we get from RNA to DNA? As it happens, there are some striking answers, backed up by surprising findings in the last few years. Gratifyingly, the new findings square beautifully with the idea of life evolving in hydrothermal vents, the setting of Chapter 1.

The environment most realistically capable of giving rise to life, whether here or anywhere else in the universe, is alkaline hydrothermal vents. Such vents constrain cells to make use of natural proton gradients, and ultimately to generate their own.

Until the discovery of hydrothermal vents off the Galápagos Islands in 1977, scientists assumed that life on earth was photosynthetic and belonged to the surface. It was the other way around: photosynthetic life came later, when cells strayed to the top where they were cooked for millions of years before evolving a way to absorb the light, and all the while the chemosynthetic life in the abyss was evolving a stability we cannot hope for.
