How did humans progress from bands of hunter-gatherers to the great civilizations of the ancient world?

At the beginning of the story, men were engaged in hunting-gathering, but with the Neolithic Revolution, this changed flatly, men began to live in large groups and agriculture emerged as a way of life. This activity managed to increase the amount of food available and from this the first great civilizations began to emerge.

the best description of postwar writers might be progressive.

following the war, writers showed a tendency to work on artistic or social matters rather than political themes. while postwar literature may not have been the greatest period of english literature, the themes provided excellent critics a high number of novels. such examples include anthony burgess, anthony powell and frank kermode, all of which can be placed under the progressive view.
