The importance of stone tools, circa 2.5 million years ago, is considered fundamental in the human development in the hunting hypothesis. [citation needed]Primatologist, Richard Wrangham, theorizes that the control of fire by early humans and the associated development of cooking was the spark that radically changed human evolution.

Living technology is the field of technology that derives its functionality and usefulness from the properties that make natural organisms alive (see life).It may be seen as a technological subfield of both artificial life and complex systems and is relevant beyond biotechnology to nanotechnology, information technology, artificial intelligence, environmental technology and socioeconomic ...
Finally, the unintended consequences of technology are unanticipated effects and impact of technology. The cell phone is an example of the social shaping of technology (Zulto 2009). The cell phone has evolved over the years to make our lives easier by providing people with handheld computers that can answer calls, answer emails, search for ...
More broadly, the researchers argue, tracking wildlife is important in understanding the unpredictable ways animals adapt to that changing planet — and a vital tool for ecology in the future ...
[291] [289] Military activities also affect land use and are extremely resource-intensive. [292] The military does not solely have negative effects on the environment. [293] There are several examples of militaries aiding in land management, conservation, and greening of an area. [294]
The 2004 UN Task Force on Science, Technology and Innovation noted that some of the advantages of nanotechnology include production using little labor, land, or maintenance, high productivity, low cost, and modest requirements for materials and energy. However, concerns are frequently raised that the claimed benefits of nanotechnology will not ...
A wheeled buffalo figurine—probably a children's toy—from Magna Graecia in archaic Greece [1]. Several organisms are capable of rolling locomotion. However, true wheels and propellers—despite their utility in human vehicles—do not play a significant role in the movement of living things (with the exception of certain flagella, which work like corkscrews).
This measure of technological innovation is widely used in empirical research, since it does not rely on the assumption that only technology affects long-run productivity, and fairly accurately captures output variation based on input variation. However, there are limitations with direct measures such as R&D.
