These changes typically occur so slowly that they are barely detectable over the span of a human life, yet even at this instant, the Earth's surface is moving and changing.

The modern world provides two new ways to find love — online matchmaking and speed dating. In the last few years, these methods have moved from a last resort for the loveless to a more accepted way for millions to try to meet their mates. While this has led to dates, relationships and marriages around the globe, it has also been a boon for enterprising researchers — providing huge datasets chronicling real world behavior. For millions of years, humans have been selecting mates using the wealth of information gleaned in face-to-face interactions — not just appearance, but characteristics such as tone of voice, body language, and scent, as well as immediate feedback to their own communications.
