In the image below panel A shows the distribution of beak sizes in populations of two finch species that each live on different islands Panel B shows the distribution of beak sizes for populations of the same two species that both live on the same island What nost likely accounts for the greater divergence in beak sizes in sympatric finch species panel B A fuligines 0 40 0 30 0 20 0 10 2 fuliginoss G fortis Los Hermanos fortis Daphine Major 4 3 6 Bill depth mm 7 B G fuliginona 0 40 0 30 0 20 0 10 faliginosa G fortis fortis 2345 6 Bill depth mm Santa Cruz a interspecific competition based on limited resources among the population in panel B b increased strength of genetic drift experienced by populations in panel B C absence of phenotypic variance Vp within each species shown in panel A of
