HALABELLA | The Jaws of Our Ancestors (Re-upload) @halabella6 | Uploaded September 2022 | Updated October 2024, 2 hours ago.
Did you know that the lower jawbone or mandible is the strongest bone in the human skulland that the jaw bone is the only double hinged bone in our body? There are many more interesting facts about the human jaw but today we shall see how our jaws evolved. As our ancestors evolved, their jaws and teeth changed in many ways and many believed that the jaws were shaped by diet.
About seven million years ago our early ancestors had long jaws which resulted in projecting face profiles and as time went by, teeth became smaller, shorter and relatively blunt. This made the face more vertical and forced the side rows of teeth to bend into a rounded arc shape. By 250,000 years ago, our direct ancestors had very short and broad jaws and had developed a pointed chin for added strength which is the reason faces are now vertical rather than projecting.
Hunter-gatherers needed big, strong jaws to chew the uncooked vegetables and meat that made up their menu most of the time. With the evolution process, our ancestors had a softer diet, consuming cooked foods like beans and cereals that didn’t demand such a high level of mouth strength. So, let us see how our jaws have changed with time
