“For a greatly improved eye
or brain to appear suddenly, a thousand
such changes [mutations] must occur at
once
in a single animal, all accidental, and yet in a favorable
direction. That would be as
unlikely as
to toss a coin in the air and have it come up heads a
thousand times in a row.”
R. Jastrow, “Selection for Perfection,” Science
Digest, December, 1981, p. 86
