‘Hobbit’ may have been human with Down syndrome

The skull (left) of LB1 is often cited as evidence for the "hobbit" species Homo floresiensis. Comparing the actual skull to composites made with her right (middle) and left (right) sides mirrored at the midline, however, shows facial asymmetry, suggesting LB1 was a Homo sapiens with developmental abnormalities.
