"A really monogamous animal is a goose – which never mates again even if its mate is killed." So it's clear that humans — who date, sleep around, form polyamorous relationships and polygamous marriages and so on — can't be defined as a monogamous species in the same way a goose can.
And humans don't have the same stunning track record as some of those animals.
"I don't think we are a monogamous animal," Pepper Schwartz, a professor of sociology at the University of Washington in Seattle, told Live Science.
Human men have less of an opportunity to sow their wild oats without repercussions, so they may end up with fewer offspring.
But they're able to identify a child as their own, based on the monogamy contract they've bought into, and they're able to invest resources in that child — and in its mother — to be sure any offspring produced will make good on dad's genetic contribution.
Unless you're lucky enough to live under a rock, you've probably heard that Ashley Madison, a dating site that caters specifically to married folks looking to cheat on their spouses, has had a massive data leak.
Around 37 million people have watched their personal data spill out onto the Internet, revealing them as cheater cheater pumpkin eaters and allowing the rest of the world to engage in some serious, ethically questionable schadenfreude.
"You get married, and after a period of time, your sexual attraction to your partner seems to wane," Biderman said. I don’t think men ever had an intent to be monogamous." It's unnatural, he insists, and that's why his Web site — which provides a discreet (erm, formerly discreet) outlet for extramarital affairs — is a net positive for the world.
"Monogamy emerged from an economic principle [ownership].  It's true that less than 5 percent of mammals in the world share life-long monogamous bonds.
So it seems as good a time as any to delve into one of the most complex and fascinating questions in social science: Are humans even meant to be faithful to one partner? Let's start off by saying that there is Ashley Madison founder Noel Biderman makes it clear that he's in the "science-shows-monogamy-is-bunk" camp.
In an interview with The Post last year, Biderman cited the book "Sex at Dawn" (which is, to be fair, an interesting read) and claimed that science was on his side. What we really meant was, women need to be monogamous.
Monogamy "could be how humans were able to push through a ceiling in terms of brain size," Kit Opie of University College London told the New York Times.
