There is no denying that babies are utterly delicious, from their peachy soft skin, to their cheruby cheeks and their we-want-to-bite-them-they-are-that-cute little toes.
But I think you'll agree with us that what really makes our knees wobble when it comes to babies, it is their really irresistible smell. One little whiff can be enough to make our ovaries do a double-take.
And now, it seems, science has figured out why this is.
According to
a new study published in
Trends in Cognitive Sciences, the whole baby-obsession thing comes down to evolution. Researchers from Oxford University determined that
all aspects of babies’ cuteness, including their smell, developed so that others would be compelled to look after them.
Mother Nature, eh?
“Infants attract us through all our senses, which helps make cuteness one of the most basic and powerful forces shaping our behavior,” said professor Morten Kringelback, who led the review in conjunction with Oxford’s Department of Psychiatry.
Kringelback and his colleagues reviewed literature about how cuteness affects the brain in order to come to their conclusions. “This is the first evidence of its kind to show that cuteness helps infants to survive by eliciting caregiving, which cannot be reduced to simple, instinctual behaviors,” he added.
The researchers determined that caregiving ignites “fundamental brain pleasure systems” in humans, similar to the ones that are engaged when we listen to music or eat delicious food, and that both men and women are affected equally, whether they have children or not.
“This might be a fundamental response present in everyone, regardless of parental status or gender,” Kringelbach added. “We are currently conducting the first long-term study of what happens to brain responses when we become parents.”
See? It's just biology making you get all ga-ga whenever there is a baby present.
