 The environmental stimuli that contribute to this variance can include climate, migration patterns, conflict, suitability for survival, and endemic pathogens.Cultural transmission can also vary according to different social learning strategies employed at the species and or individual level.Cultural transmission is hypothesized to be a critical process for maintaining behavioral characteristics in both humans and nonhuman animals over time, and its existence relies on innovation, imitation, and communication to create and propagate various aspects of animal behavior seen today.
