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:
“Like Freud, Jung believes that the human mind contains archaic remnants, residues of the long history and evolution of mankind. In the unconscious, primordial “universally human images” lie dormant. Those primordial images are the most ancient, universal and “deep” thoughts of mankind. Since they embody feelings as much as thought, they are properly “thought feelings.” Where Freud postulates a mass psyche, Jung postulates a collective psyche.”
—Patrick Mullahy (b. 1912)
“Analyze theory-building how we will, we all must start in the middle. Our conceptual firsts are middle-sized, middle-distanced objects, and our introduction to them and to everything comes midway in the cultural evolution of the race.”
—Willard Van Orman Quine (b. 1908)
“By contrast with history, evolution is an unconscious process. Another, and perhaps a better way of putting it would be to say that evolution is a natural process, history a human one.... Insofar as we treat man as a part of nature—for instance in a biological survey of evolution—we are precisely not treating him as a historical being. As a historically developing being, he is set over against nature, both as a knower and as a doer.”
—Owen Barfield (b. 1898)
