The idea that new species form when isolated from the parent group is called genetic drift. The isolation can be as small as a few miles to thousands of miles.
Better known as "adaptive radiation", it is independent evolution from a population of a species that has become geographically isolated from its parent population.
it unified many of the previously isolated concepts of geology into a single theory
In Cuvier's essay on the Theory of the Earth (1813) he was interpreted to have proposed that new species were created after periodic catastrophic floods. In this way, Cuvier became the most influential proponent of catastrophism in geology in the early 19th century.

The scientific theory is evolution.
Isolated populations evolve differences gradually as they adapt to the environment
Evolution is both fact and theory. One could say that there are laws of evolution. One such law could be: that reproductively isolated populations will always diverge genetically.

Because a tree, or better a bush, shows how evolution actually takes place. The splitting of populations going different directions to species is shown best this way. Where all species at the tip of the branches are equally evolved and connected through the trunk to all other species in the tree.
The theory of evolution posited the theory that species gradually adapt to their environment. The theory claims that humans were originally apes.
