watching a show about the first year of a human beings life. on the instincts. if you take a 1 hour old baby, hold it up and have its feet touch the ground, it will motion walking! a few months later, it won't, but if you dangle it in a bath of water, it will do it again since the gravity is less on the muscles. they're instinctvely drawn to walk.
the grabbing one is old
but get this, scientists at yale have proven that newborn infants can do math.
they did a puppet show thing where they had two dolls, took one away, and left one. the action goes on behind a screen that pops up, by the way. the baby looked, then eventually looked away. they put the doll back and secrety took it away behind that blockage, and when they showed the baby the one doll, it freaked out. they have data that all babies will respond this way. they instinctively know basic arithmatic!!!
they knew that taking one away from two, but when adding it again, the other wasn't there, they reacted.
there's a whole slew of crazy shit that links our instincts to other living relatives, like the instinct to grab is from when we had to hold on to our mothers body hair, like apes do. or when being startled, the arms and legs go out grasping, like when a baby monkey falls through a tree and reaches out to grasp, right after birth!!!
