The fact that the Kipsigis infants achieve motor development milestones earlier suggests that environmental factors play a role in modulating early motor development. It is likely that cultural practices and caregiving practices in the Kipsigis community provide more opportunities for infants to develop motor skills compared to North American infants. This highlights the importance of environmental influences on motor development.
