Such specializations are common, Brown and Wilson said, when two closely-related species live in the same area and compete for the same types of food. When related species are geographically isolated, however, the similarities tend to remain, the zoologists said.
The character displacement principle means that zoologists can no longer use as a "species yardstick" the range of differences between two species in the same area, for great differences may evolve between closely-related species living near one another. Neither can this range be applied to determine if two closely...
