The difference in tooth wearing according to anthropologists can explain feeding habits of early man. One explanation is the use of front teeth especially as tools (for cutting) also enabled evolution to favor their increased size. Teeth generally decreased in size as early man's brains became bigger and were able to process foods before eating.
