Organisms (belonging to the same species) may adapt in different ways to better exploit different environments or resources-- survival of the fittest. They also may evolve varied characteristics for attracting mates for reproduction. This means that different groups evolve differently. Over time, these groups or populations may become so different that they can no longer breed together -- and separate species are formed.
The Sibley Commission recommended that local school systems be allowed to decide if they would act by a probable court order to integrate public schools or if they would close them. When Governor Vandiver ordered to close UGA because of forced integration, people changed their minds about closing down public schools.
Sounds like rule of law to me. the rule of law states that everyone no matter what are held accountable to the same law. and trump was being held to the same law as any normal citizen here. hope that helped somewhat! :)
