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. 6 0 0 6 79 475 Tm The immigrant lineage has only a population of 20 while the native lineage 280 birds sampled. Researchers previously assumed that the formation of a new species takes a very long time, but in the Big Bird lineage it happened in just two generations, according to observations made by the Grants in the field in combination with the genetic studies.
