what makes us humans

What makes us Humans? The humans have evolved almost into a perfect form yet we still continue to evolve. To understand and see what made us humans are speaking, upright posture, hands, extraordinary brains, clothing, fire, blushing, long childhood and life after child. Anthropology its self refers to the study of human being. Pale anthropology is the study of human ancestors in the distance past. We cannot travel back in time to observe these ancestors; scientists must use other kinds of evidence to understand what happened. One thing that makes us human is our speech, our larynx or voice box sits lower in the throat in humans than in chimps one of several features that enable human speech. Human ancestors evolved a descended larynx roughly 350,000 year ago. We possess a descended hyoid bone this horseshoe shaped bone below the tongue unique in that it is no attached to any other bones in the body allows us to articulate words when speaking. Another will be that we humans have upright posture about 4 million years ago the transition from four limbed lumbering to bipedal striding came with some disadvantages. By this it frees our hands up for using tools unfortunately the changes made in our pelvis for moving on two legs in combination with babies with large brains that makes human childbirth unusually dangerous compared with the rest of the animal kingdom. So the shift produced skeletal adaptations that made them more susceptible to back, legs and joint injuries. Because the birth canal narrowed allow for more efficient locomotion labor and delivery became significantly more dangerous. Hands contrary to popular misconceptions humans are not the only animals to posses’ opposable thumbs most primates do. What makes us humans unique is how we can bring our thumbs all the way across the hand to our ring and little fingers. We can also flex the ring and little finger toward the base of our thumb to give us humans a powerful grip and exceptional dexterity to hold and
