There is no doubt that tools have played a central role in the evolutionary history of hominins, from early species like Australopithecus to the genus Homo . Inspired by the French philosopher Bernard Stiegler, this paper explores the Homo species from a Heideggerian perspective, focusing on two central ideas: (i) tools as ready-to-hand versus tools as present-at-hand, and (ii) technologies (tools) versus Technology (technological mode of being). According to Heidegger, focusing solely on tools fails to capture the deeper essence of T echnology, which is not just a tool or a set of devices, but a distinct mode of being that shapes how we perceive and act in the world. This paper argues that tools are essential for understanding the evolution of hominins not just because they reflect cognitive development or facilitate tasks like cutting thick skins, but more crucially because they signify the emergence of a distinct technological mode of being. This technological mode of being represents a fundamentally different way of being-in-the-world—perceiving the world through, and as, T echnology. Within this framework, everything is understood and valued as standing reserve. The paper addresses the issue from an evolutionary perspective, examining both the tools themselves and the ways in which chimpanzees and later extinct species, such as Australopithecus , Homo habilis , and Homo erectus , used them. The paper argues that a technological mode of being began to develop before the emergence of the Homo species and became more pronounced over time. It proposes that human development should be understood not merely as a growing dependence on tools, but as a transformation in how the world itself is disclosed—namely, within a comprehensive technological mode of being in which everything appears as standing reserve. This perspective reflects a shift in how we understand and treat our environment—not as nature (in which we dwell), but as a resource: As one progresses along the evolutionary tree from chimpanzees to humans, nature is perceived less as a living environment and more as something that stands ready for use.
