1 Will any one hold parents' fingers or a husband or wife the fingers of the house or anyone hld friends along to walk? Two uncanny things, science alone can connect in the west ."Anyone who has felt how tightly a newborn will instinctively hold onto your finger knows how heart-meltingly cute it is, but it also serves an evolutionary purpose. This phenomenon is known as the palmar grasp reflex, and it was necessary for primate babies that needed to hold onto their mothers as they swung from tree to tree. One study found that newborn humans can hold themselves and hang for ten seconds to two and a half minutes, while monkeys can hang from seven to thirty-three minutes." 2 Ruminants have multi-chambered stomachs, and food particles must be made small enough to pass through the reticulum chamber into the rumen chamber. Inside the rumen, special bacteria and protozoa secrete the necessary enzymes to break down the various forms of cellulose for digestion and absorption.Doctors also will say that is an extra feature in our body, But science alone can think this way and install fear in us. "While the appendix’s claim to fame today is sending people to the emergency room when it bursts, there was a time when it was vital to our survival. Modern humans can digest several forms of sugar–like fructose, sucrose, and glucose–but we can no longer digest cellulose, a fibrous sugar found in plants. Our herbivore ancestors needed the appendix to turn this sugar into energy, but as we became omnivores, the appendix lost its purpose and shriveled up." 3 Wisdom teeth earned their title because they usually appear between ages 17 and 21, or the time when people used to think wisdom was gained. (New theories on emerging adulthood between ages 18 to 29 may call for a renaming, however.) In our caveman days, we didn’t have forks and knives to cut up our food, and we couldn’t even cook meat. Because early humans needed to chew coarse, hearty foods, they required a broader jaw. Wisdom teeth grew in to give them more chewing power for this purpose. Because the jaw was wider, the wisdom teeth were able to grow in with no difficulties. Today, *modern food preparation and eating utensils* have eliminated our need for wisdom teeth. *Wisdom teeth are known as vestigial structures.* *These are parts of our body, such as the tailbone, that once had a use but no longer do in our modern lives*. Wisdom teeth served a purpose long, long ago when we foraged for foods like twigs and tough, raw meats. *Asians do not have wisdom teeth to contend with. OK all these factors may suit the west but Indians do not use fork and knife, then? But science says as a universal tooth "*As humans evolved, we learned how to obtain foods that were easier to eat, rather than thick vegetation that needed to be chewed with strong, powerful jaws. Our brains got bigger and our jaws got smaller, but we still had the same number of teeth. The lack of space causes our back molars, our “wisdom teeth,” to become impacted and many people need to have them surgically removed.". Wisdom teeth earned their title because they usually appear between ages 17 and 21, or the time when people used to think wisdom was gained. (New theories on emerging adulthood between ages 18 to 29 may call for a renaming, however.) At the very least, people tend to be older and “wiser” when they get their wisdom teeth than they were when their other permanent teeth erupted. KR IRS 2423
