Role of Mutated Gene in the Evolution of Large Brained, Small-Jawed Hum

position of Mutated Gene in the Evolution of Large Brained, Small-Jawed humanesThe debate with-in the anthropology firmament has been heated over the evolution of the human and the events that have lead us to where we are now. One of the major questions that is debated is how did we, humans-large brained and small jawed, evolve from primates-large jawed and small brained. interestingly enough, this debate is now being directed from outside the field by biologists and plastic surgeons. On march 25, 2004, Doctors Stedman (and others) published their findings in spirit (VOL 428) nether the title Myosin factor mutation correlates with anatomical changes in the human lineage. Their findings geological period to the gene myosin and its mutated form MYH16 and that the mutation that toke place some 2.4 million geezerhood ago as a major step in the instruction of a larger brain that we now as humans have. In this paper I aim to outline what they have discovered and invest out so me of the controversy surrounding the findings. It is not my goal to rede how the gene functions, but to rely on accepted judges conclusions that the gene is mutated but I will explain what this can say most the formation of bone structure. What the researchers found centers on the MYH16 mutation and the original myosin gene, a protein that builds strong muscular jaws. Myosin is a protein that works with other proteins to contract muscles, more importantly jaw muscles. The mutation of myosin, MYH16, causes a weaker bite. In their experiments they looked at macaque shrink from and human genes to determine how this mutation worked. They found that the gene myosin only worked in the muscles of the head used for chewing and biting. The difference between the two subjects was... ...ary springStedman, Hansell, et. al.
