Peter went first in March 1973 with the Abbots and banded about 60 or 70 medium ground finches . Because these hybrid females receive their single Z chromosome from their cactus finch father there is no gene flow on Z chromosomes between species through these hybrid females. This mating pattern is explained by the fact that Darwins finches imprint on the song of their fathers, so sons sing a song similar to their fathers song and daughters prefer to mate with males that sing like their fathers.

Why did Peter and Rosemary Grant choose to study the Finches in the Hybrid females successfully mate with male cactus finch males, whereas the hybrid males do not successfully compete for high quality territory and mates. This same response has been seen in plantsand many evolutionists, including, on the island of Santa Cruz, though, have started to appear more homogenous to. They live in the environment in which they evolved, and none has become extinct as a result of human activity. Selection suggests small changes to the actions or bodies of the birds over a generation - in other words, their life span or the life span of their offspring. The next lesson learned is that evolution can actually be a fairly rapid process. Chapter one informs Course Hero is not sponsored or endorsed by any college or university.

The Grants would study this for the next few decades of their lives. Every year for 40 years, Peter and Rosemary Grant carefully measured the physical characteristics of hundreds of individual medium ground finches living on the island of Daphne Major. Furthermore, the hybrid females successfully bred with common cactus finch males and thereby transferred genes from the medium ground finch to the common cactus finch population. Darwin's finches are a classical example of an adaptive radiation.
