The age that children start to walk is determined by genetics to a large extent. This conclusion was reached by researchers from Surrey University. Results of Scientific Study published Nature Human in Behavior magazine.
As part of the first work of this scale, scientists analyzed the data of more than 70,000 babies and created 11 genetic markers associated with the age of the first steps. It was revealed that approximately 25% of the differences at the beginning of the walk could be explained by heredity.
It was still known that environmental factors such as stimulation and physical activity affect the development of walking ability. However, as in the case of growth, some children can start walking earlier or later due to their natural predisposition.
“The first step usually takes place between eight and 24 months and is also an important development window,” he said. “This moment points to a new stage in the child’s life and is important for both parents and the baby.”
In addition, the study has shown that the genes affecting the time of the first step by the child intersect with the genes in the development of the brain. We are talking about genes responsible for the formation of the prisons and grooves of the cerebral cortex. Scientists also discovered that walking (within normal limits) was associated with the risk of developing attention and lack of attention and hyperactivity (ADHD).
