Evolution
This bird may have reached America either from Asia or from Europe (Greenland/Iceland). It is the extant parental species of one of the Spinus/Carduelis three evolutive North American radiations. That of atriceps, pinus and dominicenses finches. It has been recorded both in Aleutian Islands and the East: Labrador Peninsula and St. Lawrence River mouth (Canada). This opens the possibility that this bird entered (or still try to enter) America through Greenland/Iceland from West Europe.

Famous quotes containing the word evolution:
“As a natural process, of the same character as the development of a tree from its seed, or of a fowl from its egg, evolution excludes creation and all other kinds of supernatural intervention.”
—Thomas Henry Huxley (1825–95)
“What we think of as our sensitivity is only the higher evolution of terror in a poor dumb beast. We suffer for nothing. Our own death wish is our only real tragedy.”
—Mario Puzo (b. 1920)
“Historians will have to face the fact that natural selection determined the evolution of cultures in the same manner as it did that of species.”
—Konrad Lorenz (1903–1989)
