Lastly, and as the author states, most importantly, selection can change over time. It splits the population and forces it onto two slightly separate adaptive peaks. This explain why genes on the Z chromosome cannot flow from the medium ground finch to the cactus finch via these hybrid females, whereas genes in other parts of the genome can, because parents of the hybrid contribute equally. Following the drought, the medium ground finch population had a decline in average beak size, in contrast to the increase in size found following the 1977 drought.

Peter and Rosemary Grant have been conducting observational research studies on finch species on Galpagos Island Daphne Major for over 40 years. So it's not just a change in behavior, but a change that becomes inherited, so it is passed through the genes of the bird to the next generation. What did Peter and Rosemary Grant discover of the Galapagos finches? They also identified behavioral characteristics . 220-23. G6I ;+V'eZ9 .[i One scenario is that the two species will merge into a single species combining gene variants from the two species, but perhaps a more likely scenario is that they will continue to behave as two species and either continue to exchange genes occasionally or develop reproductive isolation if the hybrids at some point show reduced fitness compared with purebred progeny.

Higher peak depths in 1978 than before the drought. Thus, evolutionary success is based on individual selection within a single generation. In a 2006 paper in Science, Peter and Rosemary Grant provided evidence that demonstrated a character displacement event in a Galapagos finch species. Inspired by observations of finches on . On his visit to the Galapagos Islands, Charles Darwin discovered several species of finches that varied from island to island, which helped him to develop his theory of natural selection.

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. They live in the environment in which they evolved, and none has become extinct as a result of human activity. Secondly, what did Darwins research on the Galapagos Islands show?
