2. Both men and women are biologically wired to cheat.
I confess, this is the part that really freaked me out because instincts wired into our DNA are incredibly hard to override.
Fisher’s well-substantiated theory is “that sometime around 4.4 million years ago our ancestors developed a dual human reproductive strategy: serial monogamy and clandestine adultery.” Research shows that cheating serves an important purpose: It’s part of a clever reproductive strategy nature devised to guarantee that humans keep procreating.
Yep, I know what you’re thinking (because I thought the exact same thing) ― Puh-leez! The LAST thing someone wants when having an affair is to get pregnant (or get someone pregnant).
Well, perhaps in today’s society that’s the case, but our bodies are still hard-wired with incredibly primal ancient impulses. And ‘perpetuating the species’ is one of them. It seems ‘sleeping around’ offers one hugely significant biological benefit to humans … genetic variety.
