For more than four decades, the husband and wife team of Peter and Rosemary Grant travelled to the isolated Galapagos archipelago to watch evolution unfold in front of them.. on the trifling difference[s] that can determine whether a species survives, or whether it perishes. The first is that natural selection is a variable, constantly changing process. The Grants would study this for the next few decades of their lives. 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. The Grants study the evolution of Darwin's finches on the Galapagos Islands. The birds have been named for Darwin, in part, because he later theorized that the 13 distinct species were all descendants of a common ancestor. However, in the time between the droughts (beginning in late 1982), the large ground finch (Geospiza magnirostris) had established a breeding population on the island.
