The finches on this volcanic island eat, seeds by cracking them open with their beaks. For such major changes to occur, there has to be more than adaptation happening in a certain moment in time, there also has to be survival of the fittest. [8] Grant also states that there are many causes for increased competition: reproduction, resources, amount of space, and invasion of other species.[8].

This gave birds with smaller beaks an advantage when another drought hit the following year. What was the major claim Peter and Rosemary Grant concluded as a result of their research in the Galapagos Islands? Renowned evolutionary biologists Peter and Rosemary Grant have produced landmark studies of the Galpagos finches first made famous by Charles Darwin. [8] In his article "Interspecific Competition Among Rodents", he concluded that competitive interaction for space is common among many rodent species, not just the species that have been studied in detail. [6] They compared the differences of bill length to body size between populations living on the Islands and the nearby mainland. The Grants tagged, labelled, measured, and took blood samples of the birds they were studying. He observed that even though they were all finches, the various species had different shaped beaks.
