by Thomas Fraser:
"In accordance with the general climate of thinking in mid-nineteenth-century England, Darwin proposed a theory of natural selction and evolution in which the unit of survival was either the family line or the species or subspecies or something of the sort. But today it is quite obvious that this is not the unit of survival in the real biological world. The unit of survival is organism plus environment. We are learning by bitter experience that the organism which dstroys its environment destroys itself."
