A groundbreaking study conducted by researchers at the University of Surrey reveals that genetic elements significantly impact when infants take their first steps. This research, which analyzed the genetic data of over 70,000 infants, identified 11 specific genetic markers associated with the onset of walking. These findings pave the way for deeper scientific exploration into the biological mechanisms underlying this critical developmental milestone. By focusing on genetic influences, the study highlights that approximately 25% of the variation in when children begin walking can be attributed to genetics.

Beyond the genetic insights, the study underscores a broader understanding of child development milestones. Traditionally, environmental factors were considered the primary influence on when babies start walking. However, this new evidence suggests that genetics plays an equally important role. As explained by Professor Angelica Ronald, most babies achieve this milestone between 8 and 24 months, representing a significant phase transition in a child’s life. Additionally, Dr. Anna Gui emphasizes that parents need not worry excessively about early or late walking since genetic predispositions contribute significantly to individual differences in timing.

This research also uncovers intriguing connections between walking and other aspects of human development. The genetic factors influencing walking are linked to brain development characteristics such as cortical folding. Moreover, delayed walking within normal ranges is genetically associated with a lower risk of ADHD and higher educational achievement later in life. Professor Ronald concludes that these discoveries could enhance our understanding of motor skill acquisition and aid in supporting children with motor disorders or learning challenges. Ultimately, this study reassures parents about natural variations in infant development while advancing scientific knowledge in the field.
