Prehistoric 'stone Swiss Army knife' indicates early humans communicated

[Still Waters]

In a world first, a team of international scientists, led by University of Sydney archaeologist, Dr. Amy Way and Australian Museum, has revealed that early humans across southern Africa made a particular type of stone tool—a blade used for many purposes including hunting technology (such as barbs in hand thrown spears and possibly bow and arrows), for cutting wood, plants, bone, skin, feathers and flesh—in the same shape. The researchers reported this means populations must have been in contact with each other.

Known as the "stone Swiss Army knife" of prehistory, the Howiesons Poort blades were made to a similar template across great distances and multiple biomes.

The study published in Scientific Reports, found the artifacts produced in enormous numbers across southern Africa roughly 65 thousand years ago were made to a similar shape.

Fascinating stuff... thanks for sharing!

Is it possible that this is just coincidental due to an ergonomic shape?

Although if it is correct that they were ‘produced in enormous numbers across southern Africa roughly 65 thousand years ago’, and that this is not a common occurrence elsewhere or at other time periods on the continent, that that could suggest widespread societal contact.
