The Capsian culture was a Mesolithic and Neolithic culture centered in the Maghreb that lasted from about 8,000 to 2,700 BC. It was named after the town of Gafsa in Tunisia, which was known as Capsa in Roman times. Anatomically, Capsian populations were modern Homo sapiens, traditionally classed into two variegate types: Proto-Mediterranean and Mechta-Afalou on the basis of cranial morphology. Some have argued that they were immigrants from the east (Natufians), whereas others argue for population continuity based on physical skeletal characteristics and other criteria.
