Is monogamy not in our DNA?

The website Ashley Madison says it has reached the milestone of 60 million users.

If you're unfamiliar with the site, it's essentially like a dating site, but instead of singles, it's people looking for an affair.

The company's chief strategy officer says this is proof monogamy is not in our DNA.

Regardless, that's 60 million people with partners who may not agree with that opinion.
