When these three assumptions is in place, nonheritable selection produces adaptation. [Boyd, R & Silk, J. (2006). How humans evolved. United States of America]. The individuals that are the nearly fit in any species are the individuals that can gift up and reproduce the most. One of the examples would be the foundation finches of Daphne Major.

The birds that live on this island are the medium-sized ground finches (Geospiza fortis), a pocket-size bird that manages to live only by eating seeds. ray and Rosemary founder who are biologists at Princeton University conducted an important late study of the ground finches.

Peter, Rosemary and their colleagues “caught, measured, weighed, and banded nearly any finch on the island separately year of the study, which total up to around 1,500 birds.”[Boyd, R & Silk, J. (2006). How humans evolved. United States of America]. A few historic period into the! ir study, a severe drought occurred on the island. During the drought, a bulk of the small seeds had decreased, leaving only the large, hard seeds. The finches soon employ up the small, fluffy seeds. The bands on the birds’ legs bequeathed Peter and Rosemary to hide the birds during the drought. This will allow them to compare the traits of birds that survived to those that died.
