What can account for this high level of diversity in a single habitat? The remarkable distance meant that the male finch was not able to return home to mate with a memberof his own species and so chose a mate from among the three species already on Daphne Major. He was so different from the other birds that we knew he did not hatch from an egg on Daphne Major," said Peter Grant, the Class of 1877 Professor of Zoology, Emeritus, and a professor of ecology and evolutionary biology, emeritus. 522 114 l A barrier was in place that originally resulted from one immigrant being separated from its own.
