My four-year-old nephew recently drew a picture of his mother, and I was struck by the similarity to the paleolithic fertility goddess known as the "Venus of Wilendorf" (c. 24,000-22,000 BCE).  My nephew identified the circle above his mother's head as a halo.  Interestingly, his mother isn't obese.  Perhaps he was channeling the generous figure that was idealized by his ancient ancestors.  Or perhaps his mother's art history degree (earned pre-conception) affected his DNA?
