VANCOUVER, British Columbia — Hand axes, small handheld rock tools used past ancient humans, could have served as the start commodity in the homo world thanks to their immovability and utility.

The axes may have been traded between human groups and would have served every bit a social cue to others, Mimi Lam, a researcher from the University of British Columbia, suggested in her talk at the American Association for the Advocacy of Scientific discipline almanac coming together hither on February. eighteen.

"The Acheulean hand ax was standardized and shaped, became exchanged in social networks and took on a symbolic meaning," Lam said. "My proposition was that hand axes were the start commodity: A marketable good or service that has value and is used as an item for commutation."

Evolution of tools

"Humans are unique in their use of tools," Lam said. "We make stone tools and the stones are durable and become part of our external environment." These tools, she added, could have been passed down in family groups or traded with other ancient hominids. [ten Animals That Use Tools]

As humans became more intelligent, their tools become more symmetrical. "They became standardized equally a result of social norms and also utility. Eventually, over fourth dimension, hand axes were fabricated special to set them autonomously," Lam said. "There was a trend to distinguish these common tools that had a standard shape."

Examples of hand axes from about 250,000 to 700,000 years ago contain some of these special properties, such as being fabricated of pinkish rock or stone embedded with fossils. Ancient humans also fabricated large axes that stood out from the crowd.

Tool brain

These tools also had a tremendous importance in the development of homo social and cognitive intelligence. "Organisms can modify their ecological niche with tool utilize… and they tin can learn from the impacts of the construction activities on their environment," Lam said. "This has been actually important in the evolution of humans."

Making tools takes a lot of brainpower, Lam said. The ancient humans "had to have a mental template or an idea of the tools they wished to fashion," Lam said. They were able to sympathize how unlike tool shapes had dissimilar purposes. "That process is the feedback process between what you are doing and the event you are having on your environment."

Hand axes were so important to ancient humans that they adult as icons and symbols that are still used by lodge. (For instance, they are frequently found on the covers of metal albums.) These tools eventually transformed into beingness used as literal currency. The Chinese exchanged tools equally coin, which eventually turned into representations of tools, which were even featured on coins.
