AI Summary

The discovery of fossilized skulls from ancient human species suggests a long-standing connection between infant helplessness and skull development. Fossils of Homo erectus and H. floresiensis show skull deformities that resemble those found in modern human babies who consistently rest on one side of their head. This similarity implies that the physical characteristics associated with infant helplessness have been present in human ancestors for millions of years. The findings indicate that the relationship between skull development and infant behavior may be more deeply ingrained in human evolution than previously thought.
