  That's a reasonable enough assertion! You could argue that exploration, migrations, colonization are but the emergent/complex behaviors described by more fundamental principles in psychology, sociology, biology. Conway's game of life, in a way. History being a mere factual, chronological account — a log. You are thereby operating at a high-level, manipulating complex umbrella objects like "great migrations", "local population pressure", each of whose words (composite concepts) map to lower-level datapoints — e.g. like some eternal tension (psy., soc., hist., bio...) between a desire to look inwards (for security? familiarity? survival, support?) and a drive to seek outwards (for growth? curiosity? lack, want, need?)
