On the back of the human skull, there is a small bump, below which is an opening where the spinal cord enters the skull. Which of the following statements provides the best evolutionary explanation for the location of the opening near the base of the skull? It is associated with the change to a bipedal stance. It provided greater protection for the spinal cord. It allowed for the hominin brain to grow much larger than other primates. This change was necessary for the increase in size from prosimian forms to anthropoid forms.

Human Evolution

Human evolution is the process of evolution of humans from early man to anatomically modern humans. The process of evolution in humans leads to the gradual development of traits like bipedalism. Humans are the highly social animals that make them the most advanced animal on Earth.  Human evolution is an outcome of interaction among the following processes:
