Answer on Genetics Question for Amarjit Singh
This phenomenon was also studied on the example of two species of Galapagos finches (Geospiza fuliginosa and Geospiza fortis). In this case character displacement arises from the competition for seeds.
Both of them are seed eaters. When they occur together, they compete for medium-sized seeds. This reduces the effective abundance of that resource for both species. Therefore, this creates an evolutionary pressure on both species that tends to enhance the differences in beak size over time.
