Fire, fueled with wood and charcoal, allowed early humans to cook their food to extend its digestibility, improving its nutrient value and broadening the number of meals that could possibly be eaten. The use of tools by early humans was partly a strategy of discovery and of evolution. Early humans evolved from a species of foraging hominids which were already bipedal, with a mind mass approximately one third of contemporary people. Tool use remained relatively unchanged for many of early human history. Approximately 50,000 years in the past, using instruments and complicated set of behaviors emerged, believed by many archaeologists to be related to the emergence of fully modern language.

- Technology is often a consequence of science and engineering, though technology as a human activity precedes the 2 fields.
- Advances in technology on this era allowed a more dependable provide of meals, adopted by the broader availability of consumer goods.
- This new-found knowledge may then be utilized by engineers to create new instruments and machines such as semiconductors, computer systems, and different forms of advanced technology.
- The Renaissance era produced many innovations, together with the printing press (which facilitated the communication of data), and technology turned more and more associated with science, beginning a cycle of mutual advancement.
Other technological advances made during the Paleolithic era had been clothing and shelter; the adoption of each technologies cannot be dated exactly, however they had been a key to humanity’s progress.

Clothing, tailored from the fur and hides of hunted animals, helped humanity expand into colder regions; humans started to migrateout of Africa by 200 ka and into other continents such as Eurasia.
