It occurs over many generations.

It applies to an entire population.

It happens at the genetic level.

Explanation:

Evolution is how the species change over many generation by passing along the genes that allow the species to be more adapted to the environment in which it is inserted, making it easier to procreate and survive. That's why we call it "the survival of the fittest". It isn't about strength, but about how adapted to the surroundings in order to keep living and procreating a species is. This change happens over the course of many generations since the more adapted genes are passed along to the offspring of the members of that species that have been surviving.

abraham lincoln, according to anyone who was connected with agriculture, represented the worst of northern politicians. shortly after lincoln was elected, south carolina seceded from the union. they along with other southern states, retained their anger. in a way, it was their own fault: the democrats were split in the south. some wanted slavery to be extended in other states that were about to join the union and some didn't want it badly enough. lincoln had a solid backing from his party: the republicans were united in not wanting slavery to be expanded.
