The first of our kind. Composite reconstruction of the earliest known Homo sapiens fossils from Jebel Irhoud (Morocco) based on micro computed tomographic scans of multiple original fossils. Dated to 300 thousand years ago these early Homo sapiens already have a modern-looking face that falls within the variation of humans living today. However, the archaic-looking virtual imprint of the braincase (blue) indicates that brain shape, and possibly brain function, evolved within the Homo sapiens lineage.

The first of our kind. Virtual palaeoanthropology is able to correct distortions and fragmentations of fossil specimens. This reconstruction of the Irhoud 11 mandible allows its comparison with archaic hominins, such as Neandertals, as well as with early forms of anatomically modern Humans.

Part 1: CT scan of a child’s mandible from Jebel Irhoud. Jean-Jacques Hublin explains that the Jebel Irhoud child was approximately 7.5-8 years old, based on dental microstructure analyses. Part 2: Reconstruction of a human skull from Jebel Irhoud. In the MPI EVA's 3 D laboratory Jean-Jacques Hublin and Philipp Gunz discuss the shape of the skull and its brain. The internal cavity of the skull shows that this brain was rather large, but quite different in shape from that of extant humans.
