Motor skills

Scientists have discovered that prenatal exposure to chlorpyrifos, a common insecticide used in agriculture and previously indoors, is linked to brain abnormalities and reduced motor skills in children. Research conducted on New York City children shows the pesticide may cause lasting developmental damage to the brain before birth.

Scientists have solved the mystery of why almost everyone is right-handed, and the answer may lie in how humans learned to walk. The discovery sheds light on the development of human motor skills and handedness. This breakthrough could lead to a better understanding of human evolution and behavior.
