My reading of the book of life . . . sees at work throughout animal
evolution a strong selective pressure favoring the creation of
neuronal networks of increasing complexity. If our species
disappears, I am inclided to predict its replacement by another
intelligent species with perhaps greater powers than we have,
notably more wisdom.
. . . Life on Earth has the time to recapitulate
one thousand times the emergence of the human species from its last
common ancestor with chimpanzees, and some twenty times the whole
history of mammals. Many wonderful things can still happen in the
next five billion years, and no doubt will.
