Interesting Statements by Different
People:

Michael Shermer, author of Why Darwin
Matters: Natural selection is a description of
a process, not a force. No one is “selecting”
organisms for survival in the benign sense
of pigeon breeders selecting for desirable
traits in show breeds or for extinction in the
malignant sense of Nazis selecting
prisoners at death camps. Natural selection
is nonprescient—it cannot look forward to
anticipate what changes are going to be
needed for survival.,,,,

David Ginger, University of Washington in
Seattle: one of the keys to unlocking
organic thin-film's capabilities is to better
understand how electrical charges move
through solar cells by studying their
structure at the nano level. [2]
