The Myoclonic Jerk

Scientists put babies on a platform that had plexiglass beyond the edge of the surface, kind of like the skywalk of the Grand Canyon I've never been. They wanted to see if the babies and little animals would go over the imaginary cliff. But surprise, most of the human and animal babies did not. The hypnic jerk started with our primate ancestors who slept in trees,. And when they fell from these trees, their bodies would tense up before impact.
