Shadow Life

Shadow life is a theory proposed by Paul Davies, which suggests that life may exist on Earth which has no evolutionary connection with any form of life currently known to science. If shadow life actually exists, this would greatly increase the prior probability of extraterrestrial life developing on other Earth-like planets.


Famous quotes containing the words shadow and/or life:

    the shadow of a difference
    falling between
    note and note,
    a hair’s breadth
    defining them.
    Denise Levertov (b. 1923)

    Taking food alone tends to make one hard and coarse. Those accustomed to it must lead a Spartan life if they are not to go downhill. Hermits have observed, if for only this reason, a frugal diet. For it is only in company that eating is done justice; food must be divided and distributed if it is to be well received.
    Walter Benjamin (1892–1940)
