First Life
Billions of years ago, deep under the ocean, the pores and pockets in minerals that surrounded warm, alkaline springs catalyzed the beginning of life
Four billion years ago, back when life began, our planet was a very different place. Earth spun more rapidly on its axis. A day lasted only four or five hours. The Moon was much closer, and giant meteorites pelted the planet. Under these conditions of constant, chaotic change, there was only one place of constancy, a warm spring in the relative safety of the deep ocean floor. There, protected from ultraviolet radiation, existed a place that never dried out, never got too hot or too cold, never became too acidic or too alkaline. Life began there, inside the membranous froth of minerals that surrounded these hydrothermal springs, and the minerals themselves catalyzed the first chemical reactions that made proteins and nucleic acidsprecursors to the earliest living things. Every kind of life, including us, carries the mark of that first catalysis in the form of tiny mineral clusters at the centers of our enzymes, still doing the jobs they began so long ago.

The discovery in Ethiopia during the course of 1992 to 1994 of fossils more than 4 million years old was finally revealed to the scientific world on October 2 of this year in a special edition of the journal Science. Many thousands of pieces of fossilized bone were recovered, reconstructed and shown to be the most complete, oldest specimen on the human lineage and named Ardipi
Australopithecus
