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 best history is but like the art of Rembrandt; it casts a vivid light on certain selected causes, on those which were best and greatest; it leaves all the rest in shadow and unseen.”
—Walter Bagehot (1826–1877)
“Tomorrow in the offices the year on the stamps will be altered;
Tomorrow new diaries consulted, new calendars stand;
With such small adjustments life will again move forward
Implicating us all; and the voice of the living be heard:
“It is to us that you should turn your straying attention;
Us who need you, and are affected by your fortune;
Us you should love and to whom you should give your word.””
—Philip Larkin (1922–1986)
