03:13
The Three Age system categorizes artifacts into stone, bronze, and iron tools based on their composition and assumes that they appeared in that order over time, although there is debate and overlap in defining the dividing lines between the ages, and these ages only apply to Eurasia.
04:37
The Stone Age was characterized by the development of sophisticated stone tools, the construction of large structures like Golbeki Tempi and Stonehenge, and the introduction of metallurgy with the use of copper.
06:03
Bronze, a mixture of copper and tin, was a significant advancement over copper as it was harder, didn't corrode, had a lower melting point, and allowed for the creation of complex objects like axes and swords, leading to the development of larger social institutions and the rise of bronze-age civilizations.
07:32
The Bronze Age was short-lived and relied on access to tin, while the advancement in metalworking during this time led to the ability to work with iron, which was more abundant and eventually led to the rise of iron age civilizations.
09:00
Iron Age civilizations, including the Romans, Greeks, Persians, and Chinese, emerged around 500 to 800 AD, with the first recorded instances of ironworking coming from ancient Egypt and sub-Saharan Africa, which skipped the bronze age due to a lack of accessible tin.
