The question of what makes us human is a common one among anthropologists and scientists alike. Many factors of evolution are explored to determine the point in history where our ancient ancestors branched away from primate lines, and there is no greater contention in anthropology than when to date humans. This is an important topic of study because it relates to the origin of the human genus as well as species and allows for the broader study of humanity. By pinpointing what behaviors shifted human evolution away from primates, one can continue to examine further behaviors and cultures that developed as uniquely human. From physical bone structure, to behavioral change, and even socialization, all aspects of what makes humans have been examined. Recently, there is a more contemporary argument emerging that cooking and human's control of fire is the transformative movement leading to human development. The idea behind this is that fire and cooking led to brain development and a social evolution that produced all things which are uniquely human. The "cooking hypothesis"- a term used by those who believe fire and cooking is the point of human origin- works to encompass all other arguments for what makes us human. This argument is breaking down past theories and assertions about human evolution and will be the focus of this essay as the answer to what led to human origins.
