To better understand why we lie to those we love, it helps to take a close look at our human nature.
What does science tell us about our romantic relationships and how they work? Over the past several decades thousands of researchers have been exploring this topic. And currently a lot is known about our intimate relationships, the purpose they serve, and what is likely to happen as two people become sexually involved.
But, to truly understand our romantic relationships, we first need to take a step back and look at the driving force that shaped the nature of every living thing on this planet, including humans and our relationships.
In particular, we need to talk about how "evolution" shaped both our human nature and how we relate to each other.
