Upright hominids gained advantages such as improved vision, which allowed them to be more aware of their surroundings. However, this visibility also made them more noticeable to predators. The vulnerability of humans in the wild is evident, as most large animals possess greater strength and speed. This contrast highlights our precarious position in nature, where survival is not guaranteed.

Despite these disadvantages, modern humans compensate with intellect and dexterous hands. Our brains enable us to develop strategies for protection, while our ability to manipulate tools allows us to defend ourselves from a distance. This unique capability makes our physical frailty somewhat less critical, showcasing the adaptive nature of our species.
