Monogamy in Our Genes?

Monogamy in Our Genes?

June 16, 2004 -- Imagine Turn a bed-hopping lothario into a dedicated, Monogynous mate with the Impudent of a Beginning Electrical switch. A new Cogitation shows it may be possible, at To the lowest degree for the notoriously promiscuous Hayfield mole.

Accomplishing the Aforesaid Deed in Humanity may be a bit More Complex, but Investigators say they've Recovered a Factor that appears to Rich person a profound effect on the Ethnic behavior of animals.

The Factor, Identified as the Antidiuretic hormone Sense organ, is Set in the brain's reward center and may Besides be involved in drug addiction.

Researchers say the findings may help explain the neurobiology behind romantic love as well as disorders Much as autism that affect how people Class Ethnic bonds.

The Monogamy Gene

In the Cogitation, Investigators used a Atoxic Computer virus to Carry-over the Factor from Monogynous male prairie Field mouses, who are Identified to Class Womb-to-tomb bonds with a Only mate, into the brain of Hayfield Field mouses, who mate with Triple partners and lack Antidiuretic hormone Sense organs in their brain's reward center.

A few Years later, the Hayfield Field mouses had Antidiuretic hormone Sense organs levels Mistakable to those Recovered in the prairie Field mouses.

Researchers paired the animals with sexually receptive Couple and allowed them a day to get to know each Another before the males were Tending a Faithfulness test.

Each Field mouse was allowed to wander Betwixt his 1st partner and a new potential mate. The Cogitation showed that Some the prairie Field mouses and the Beginningally Qualified Hayfield moles huddled close to their Innovational partner Spell the untreated Hayfield Field mouses behaved like loners and Worn out Clip by themselves.

The results appear Promulgated in the June 17 issue of Nature.

Are Animals Addicted to Love?

Researchers say previous research has shown that these Antidiuretic hormone Sense organs may play a role in Ethnic disorders, Much as autism, that make it difficult to Class Ethnic bonds.

Studies in Humanity Rich person Besides Recommended that the Aforesaid brain pathways involved in Classing romantic relationships may Besides be involved in drug addiction.

"The brain process of Soldering with one's partner may be Mistakable to becoming Dependent to drugs: Some activate reward circuits in the brain," says Investigator Miranda Lim, a postdoctoral Boyfriend at Emory University, in a Word release.

Pair Soldering in Humanity is a More More complex process than in moles, and Investigators say Ethnic, economic, historic, and individual differences all play a role.

"Our Cogitation, Still, provides evidence, in a Relatively Plain animal Exemplary, that changes in the activity of a Only Factor Deeply can change a Central Ethnic behavior of animals Inside a species," says Investigator Larry J. Young, PhD, of Emory University's School of Medicine, in the release.

"It is intriguing," says Young, "to consider that individual differences in Antidiuretic hormone Sense organs in Humanity Power play a role in how Otherwise people Class relationships."

Researchers say Few than 5% of mammals are Monogynous by nature, and these findings may Crack new clues to the Beginning and biological processes behind Monogamousness and how Humanity Class Womb-to-tomb Ethnic bonds.

In a related essay Promulgated in the Aforesaid journal, Melvin Konner, of the department of anthropology at Emory University in Atlanta, writes, "We do not yet know if a Mistakable Arrangement helps explain male attachment in non-human primates, More less Humanity, but a medicine that Power someday be Cracked to certain men is an Exciting prospect.

"We are a long way from a commitment pill, but Peradventure closer to a Clinical neurology of romance," writes Konner.
