Lo que una punta de flecha encontrada en Sudáfrica revela sobre la inteligencia de nuestros antepasados

El hallazgo, que procede de depósitos de hace más de 60 000 años, se parece mucho a miles de puntas de flecha de hueso usadas por los cazadores-recolectores indígenas desde el siglo XVIII hasta el XX.

What a bone arrowhead from South Africa reveals about ancient human cognition

The artefact comes from deposits dated to more than 60,000 years ago. It closely resembles thousands of bone arrowheads used by the indigenous San hunter-gatherers from the 18th to the 20th centuries.

How our African ancestors made sound in the Stone Age

Working with bone artefacts from archaeological sites in South Africa’s southern Cape region, we’ve been able to show that some implements might have been used for sound production in the past.
Bone artefacts from various South African Stone Age archaeological sites have been interpreted as arrowheads. J. Bradfield (as published in Bradfield, J. & Choyke, A. 2016. Bone technology in Africa.

Species-level identification of bone tools has been undertaken for the first time in southern Africa.
