Hutton believed that the earliest occupants of India were probably the Negrito race who, however, have left little trace in India. They are followed by the Proto-Austroloid. Next came an early branch of the Mediterranean race speaking an agglutinative tongue from which the present Austro-asiatic languages are derived. These are credited with a crude knowledge of agriculture and a megalithic cult. From Eastern Europe came a later wave of Mediterranean immigration, more advanced than the earlier hords, equipped with knowledge of metals and who developed the city states.
Plan B: Use Plan B if you have only a few, larger similarities or differences. After your introduction, in the next paragraph discuss one similarity or difference in BOTH works or characters, and then move on in the next paragraph to the second similarity or difference in both, then the third, and so forth, until you're done. If you are doing both similarities and differences, juggle them on scrap paper so that in each part you put the less important first ("X and Y are both alike in their social positions . ."), followed by the more important ("but X is much more aware of the dangers of his position than is Y"). In this format, the comparing or contrasting goes on in EACH of the middle parts.
