For humans, monogamy is not biologically ordained. According to evolutionary psychologist David M. Buss of the University of Texas at Austin, humans are in general innately inclined toward nonmonogamy. But, Buss argues, promiscuity is not a universal phenomenon; lifelong relationships can and do work for many people.
But if humans were cut from exactly the same cloth as other mammals, a faithful spouse would be an unusual phenomenon. Only 3 percent to 5 percent of the roughly 5,000 species of mammals (including humans) are known to form lifelong, monogamous bonds , with the loyal superstars including beavers, wolves and some bats.
Balance of evidence indicates we are biologically inclined towards monogamy. Science has yet to definitively pronounce on whether humans are naturally monogamous (lifelong male-female breeding pair) or polygamous (single male breeding with more than one female).
In essence, men are only socially monogamous rather than genetically monogamous.
According to the New York Times, a 2011 paper showed that early humans, or hominids, began shifting towards monogamy about 3.5 million years ago—though the species never evolved to be 100% monogamous (remember that earlier statistic).
Monogamy in humans is beneficial because it increases the chances of raising offspring, but it is actually very rare in mammals – less than 10 per cent of mammal species are monogamous, compared with 90 per cent of bird species. Even in primates, where it is more common, only about a quarter of species are monogamous.

Men were almost twice as likely to say they are polyamorous or want to be polyamorous.
Scientists at University College London believe monogamy emerged so males could protect their infants from other males in ancestral groups who may kill them in order to mate with their mothers.
Although the Old Testament describes numerous examples of polygamy among devotees to God, most Christian groups have historically rejected the practice of polygamy and have upheld monogamy alone as normative. Nevertheless, some Christians groups in different periods have practiced, or currently do practice, polygamy.
New DNA research has unexpectedly revealed that they were even more promiscuous than we thought. New DNA research has unexpectedly revealed that they were even more promiscuous than we thought.
Could we mate with other animals today? Probably not. Ethical considerations preclude definitive research on the subject, but it's safe to say that human DNA has become so different from that of other animals that interbreeding would likely be impossible.
Monogamy is not simply unrealistic; it is unnatural. You do not find it often in the animal kingdom, and where you do it is generally born of an evolutionary necessity. The necessity of monogamy among humankind has evaporated.
What we can know for sure is that even though it appears humans may have a quasi-mating season, it is not really a true one as women are receptive to sex year-round and ovulate every 28 days, not annually.
If we mean realistic for the species of humans, then the answer clearly is yes. In various cultures around the world people are able to engage in lifelong monogamous relationships.
The average time for each couple (that is, averaged across all the times they had sex) ranged from 33 seconds to 44 minutes. That's an 80-fold difference. So it's clear there's no one “normal” amount of time to have sex. The average (median, technically) across all couples, though, was 5.4 minutes.
Evolution dictates that genes have the final say. And if there is one thing genes want, it is to spread as far and wide as possible. That is why monogamy is rare among mammals. Females have to wait for a long gestation period to have a child, where as males could go and inseminate many other females in that time.
“The human mating system is extremely flexible,” Bernard Chapais of the University of Montreal wrote in a recent review in Evolutionary Anthropology. Only 17 percent of human cultures are strictly monogamous.
We now know that the first hominins, which emerged more than seven million years ago, might have been monogamous. Humans stayed (mostly) monogamous for good reason: it helped them evolve into the big-brained world conquerors they are today.
Multiple U.S. states (including California, Washington, Louisiana, and Rhode Island) have explicitly recognized the families with multiple parents, such as step-families, adoptive families, and families with CNM parents.
Polyamory is usually not related to a religion and is unrelated to marriage, although some polyamorous people are married or have participated in commitment ceremonies with their partners.
Instead, biological indicators suggest a mating system where both sexes form a long-term pairbond with a single partner (Møller, 2003). And while polygyny was likely present in the human past, as it is across contemporary human societies, the weight of evidence seems to support social monogamy.
Summary: In cultures that permit men to take multiple wives, the intra-sexual competition that occurs causes greater levels of crime, violence, poverty and gender inequality than in societies that institutionalize and practice monogamous marriage.
Ancient Greece and ancient Rome. The ancient Greeks and Romans were monogamous in the sense that men were not allowed to have more than one wife or to cohabit with concubines during marriage.
