Men can hammer a nail with a few, clean sharp strokes and are better at it than women, says a new study.
Duncan Irschick and colleagues at the University of Massachusetts in Amherst (U-M) measured hammering performance in men and women.
They found that men are more accurate than women when hammering in poorly-lit conditions. Conversely, women are more accurate in the light, regardless of target size.
"We believe that our research indicates that humans have remarkable compensatory abilities during difficult motor tasks such as hammering in the dark," says Irschick.
In future studies, he is planning to focus on understanding how hammering ability evolves in humans from early development to adulthood, said a U-M release.
Irschick presented his findings at the Society of Experimental Biology annual meeting in Glasgow (UK) on Sunday.
