In "Origins: How Life Began," the second hour of our four-part
miniseries, NOVA zeroes in on the mystery of life. Join the hunt for
hardy microbes that flourish in the most unlikely places: inside
rocks in a mine shaft two miles down, inside a cave dripping with
acid as strong as a car battery's, and in noxious gas bubbles
erupting from the Pacific Ocean floor. The survival of these tough
microorganisms suggests they may be related to the planet's first
primitive life forms. Host Neil deGrasse Tyson deepens the search by
investigating tantalizing and controversial chemical "signatures" of
life inside three-billion-year-old rocks and meteorites found around
the world.
