This chapter examines media phenomena from an evolutionary psychological perspective. Based on Charles Darwin’s theories of natural and sexual selection, this chapter illuminates why humans produce, select, and use media; it also considers the effects of media. Furthermore, it discusses whether media phenomena are an adaptation for evolutionarily relevant problems or a byproduct of evolutionary adaptations. Finally, various studies are described that discuss media selection, media usage, and effects using explanatory approaches from evolutionary media psychology: a) Sex-typical preferences for media content, b) Smartphones as a social signal in the context of mate selection and same-sex competition, c) Horror fans and morbid curiosity, d) Talking machines as social actors, and e) Online mate selection, gossip, and self-presentation in social media.
