Mohamed Sahnouni and Sileshi Semaw are taking part in the 27th meeting of this international scientific society (SAfA 2025), held in Portugal, where they are sharing their studies on the origins of human behavior in Africa
The archaeologists from the Centro Nacional de Investigación sobre la Evolución Humana (CENIEH), Mohamed Sahnouni and Sileshi Semaw, have participated this week in the 27th Biennial Meeting of the Society of Africanist Archaeologists (SAfA 2025), held in Faro, Portugal. This internationally significant event brings together specialists in African archaeology to discuss the latest discoveries related to human evolution on the continent. During the meeting, they presented their research on archaeological sites in Algeria and Ethiopia.
Specifically, Sileshi Semaw gave a presentation titled "The 2.6-Million-Year-Old OGS-7 and East Gona stone assemblages, Afar, Ethiopia", focused on the oldest known stone tool assemblages, discovered at Gona (Ethiopia). Dated to 2.6 million years ago, these stone tools provide valuable insight into the earliest technological behaviors of our ancestors.
For his part, Mohamed Sahnouni presented new results from a multidisciplinary investigation in his talk titled "New multidisciplinary research at the Lower Paleolithic site of Tighennif, Algeria". This study advances our understanding of human behavior in North Africa during the Lower Paleolithic, based on findings from the emblematic site of Tighennif, one of the most significant in the region.
CENIEH’s participation in SAfA 2025 reinforces its role as an international reference center for the study of human origins and its strong commitment to scientific excellence in research on human evolution in Africa.
