I would have to assume there's some ecological pressure they're either experiencing or shielded from. If they're under environmental pressure, they are either exceptionally developed to endure environmental changes or they're adapting to the environment in ways that don't reflect in their physiology. If they've just found a niche biome where the ecological conditions are fairly static, and they're well suited to the environment, what changes would you see other than some generic genetic drift?
