Are humans hardwired for monogamy?

Evolution steered humans toward pair bonding to ensure the survival of genes. But humans tend to get restless.

HELEN FISHER: Monogamy is natural. Adultery is natural too. Neither are part of the supernatural but I don't think people really understand monogamy. "Mono" means one and "gamy" means spouse. One spouse. Polygyny. "Poly" means many. "Gyny" means women. Many women. We are an animal that forms pair bonds. We are basically mono-gamous, monogamous. We're also adulterous. I think we've evolved what I call a dual human reproductive strategy. A tremendous drive to fall in love and pair up and rear our children as a team of two. And a predisposition, some people, of restlessness. An inclination to be adulterous. And we tend to be an animal that, a creature, that forms a pair bond for a period of time and breaks that pair bond and forms a new pair bond. Serial monogamy and clandestine adultery. So when did monogamy evolve? I think it evolved over 4.4 million years ago when our ancestors were coming down out of the trees. Ninety-seven percent of mammals do not pair up to rear their young. Elephants couldn't be bothered. Giraffes couldn't be bothered. Gorillas form a harem. People form pair bonds. Everywhere in the world the vast majority of people have one partner at a time.

Even in societies where the man can have a harem, polygyny, only about five to ten percent of men actually get enough cows or goats or money or education or some other sort of status to win a group of women. A woman will not be the second wife of a poor man. Only if the prerequisites outweigh the costs. I think human pair bonding evolved millions of years ago along with brain circuitry for romantic love and for deep attachment to a partner. I think it evolved for an ecological reason. Our ancestors were forced down from the trees by 8, 7, 6 million years ago, they had to begin to walk on two legs over very dangerous open grasslands. And at that point they began to stand up on two feet instead of four to carry weapons and to carry tools and to carry food back to a place where they could eat unmolested by predators. And with the beginning of walking on two legs instead of four, females began to have to carry their babies in their arms instead of on their backs. And if I were to give every woman in the world a 20 pound bowling ball to carry around for the next four years and also try to carry sticks and stones and collect fruit and vegetables and run from lions, et cetera, they too would look around for a mate.

So by four million years ago in order to survive females began to need to form a pair bond at least long enough to help raise a child through infancy. I don't see how in these open grasslands a male could have really protected a harem of females not only from wild animals but from other males. So pair bonding became essential to females and suitable to males and humanity went over what I call the monogamy threshold and we began to evolve this drive to fall in love and form a pair bond and rear our children as a team, a hallmark of the human animal today.

  • Monogamy is natural, but adultery is, too, says biological anthropologist Helen Fisher.
  • Even though humans are animals that form pair bonds, some humans have a predisposition for restlessness. This might come from the evolutionary development of a dual human reproductive strategy.
  • This drive to fall in love and form a pair bond evolved for an ecological reason: to rear our children as a team.

  • A new study shows e-commerce sites like Amazon leave larger greenhouse gas footprints than retail stores.
  • Ordering online from retail stores has an even smaller footprint than going to the store yourself.
  • Greening efforts by major e-commerce sites won't curb wasteful consumer habits. Consolidating online orders can make a difference.

Childhood sleeping problems may signal mental disorders later in life

Chronic irregular sleep in children was associated with psychotic experiences in adolescence, according to a recent study out of the University of Birmingham's School of Psychology.

Personal Growth
  • We spend 40 percent of our childhoods asleep, a time for cognitive growth and development.
  • A recent study found an association between irregular sleep patterns in childhood and either psychotic experiences or borderline personality disorder during teenage years.
  • The researchers hope their findings can help identify at-risk youth to improve early intervention.

    Why do people believe in conspiracy theories?

    Are we genetically inclined for superstition or just fearful of the truth?

    Videos
    • From secret societies to faked moon landings, one thing that humanity seems to have an endless supply of is conspiracy theories. In this compilation, physicist Michio Kaku, science communicator Bill Nye, psychologist Sarah Rose Cavanagh, skeptic Michael Shermer, and actor and playwright John Cameron Mitchell consider the nature of truth and why some groups believe the things they do.
    • "I think there's a gene for superstition, a gene for hearsay, a gene for magic, a gene for magical thinking," argues Kaku. The theoretical physicist says that science goes against "natural thinking," and that the superstition gene persists because, one out of ten times, it actually worked and saved us.
    • Other theories shared include the idea of cognitive dissonance, the dangerous power of fear to inhibit critical thinking, and Hollywood's romanticization of conspiracies. Because conspiracy theories are so diverse and multifaceted, combating them has not been an easy task for science.
