Humans exhibit vestigial traits, and just like vestigial organs they are evolutionary remnants of features useful in an ancestor, but now either useless or used in a different way.
One such behavior is the “grasping reflex” of human infants. When you put your finger into the palm of an infant, it will immediately and securely grasp it. The grasp is so tight that it’s sometimes hard to make the kid let go! It is said — though I have never seen this demonstrated — that up to a couple months of age a baby can hang suspended from a horizontal stick for several minutes.
The grasping reflex is evident in the feet, too. If you put your finger along a baby’s toes from the sole side, it will grasp with those toes. And when a baby is sitting down, its “prehensile” feet assume a curled-in posture, much like what we see in an infant or an adult chimp.
One of my friends has a four-month-old daughter, and I asked her to take a picture of the grasping reflex and the prehensile foot posture for this website. Here are both in a single picture. Although the kid is somnolent, she still holds on firmly. The sitting posture of a young chimp is given for comparison.
Its believed our chimp ancestors needed this reflex so a kid could hold on to its mum fur and not fall when the mum went about her business in the jungle

Attempting to justify kawasaki
i dont know about this but a human infant despite being inept in so many tasks grabs a adult just like a monkey. To carry a kid who is old enough to begin to walk, you just support the buttocks and it grabs you firmly about the neck.
