Excerpt:

Fathers, it turns out, contribute far more to their children than many of us realize.

Those contributions begin during pregnancy, before fathers and their children have even met. Studies show that the death rate of infants whose fathers were not around during pregnancy is nearly four times that of those with engaged dads. And depression in fathers during their partners’ pregnancies — which is more common than most people realize — can increase the child’s lifelong risk of depression.

After birth, children whose fathers play with them, read to them, take them on outings, and care for them have fewer behavioral problems during their early school years. And they have a lower risk of delinquency or criminal behavior as adolescents.

Some of fathers’ contributions are surprising. One might guess, for example, that mothers have more influence than fathers on their children’s language development. Despite the growing number of women in the workforce, mothers still spend more time with children in many families than fathers do.

But that turns out not to be the case. Lynne Vernon-Feagans of the University of North Carolina, who studies language development, has found that when it comes to vocabulary, fathers matter more than mothers.

In middle-class families, she found that parents’ overall level of education — and the quality of child care — were both related to children’s language development. But fathers made unique contributions to children’s language development that went beyond the contributions of education and child care.

When fathers used more words with their children during play, children had more advanced language skills a year later. And that is likely also linked with later success in school.

And when Vernon-Feagans looked at poor families, she found much the same thing. She visited families when a child was 6 months old, 15 months old and 3 years old. She found that fathers’ education and their use of vocabulary when reading picture books to their children at 6 months of age were significantly related to the children’s expressiveness at 15 months and use of advanced language at age 3.

This held true no matter what the mother’s educational level was or how she spoke to the children.

“I do think our children see it as very special when they do book reading with their fathers,” Vernon-Feagans says. “They may listen more and acquire language in a special way.”

Several studies suggest that fathers also have a powerful influence on their daughters’ sexual behavior during adolescence.

This became clear in 2011 when Frayser High School in Memphis, Tenn., attracted national attention for its high pregnancy rate: About one in five of its female students was either pregnant or had recently given birth.

One local official blamed the high pregnancy rate on television shows such as MTV’s “16 and Pregnant” and “Teen Mom.” The official worried that these shows were encouraging Frayser’s female students to have unprotected sex earlier and more often.

That explanation seemed to make sense. But when psychologist Sarah E. Hill of Texas Christian University examined the situation, she noticed another striking fact: One in four households was headed by a single mother. Studies have revealed “a robust association between father absence — both physical and psychological — and accelerated reproductive development and sexual risk-taking in daughters,” she wrote.

The fathers’ absence in so many families was likely more important than what their daughters watched on television.

These are just a few of the many, many studies in recent years that have demonstrated a powerful link between fathers and their children.

It’s a good summary of the research. We all know that research clearly shows that single motherhood is bad for children, generally. The harm is different depending on whether the child is a boy or a girl, but both sexes are harmed by father absence. So then why do we think that same-sex marriage will be good for children? Either the child will be lacking their biological mother or father. In the case of two lesbians, the child they raise will be facing all the problems described in the research on children raised without their fathers. Why is it a good thing to screw over children just so that adults can be more free to be selfish and destructive?
