Professor Wins “Ig Nobel” for Study of Pregnant Women

Anthropologist Liza Shapiro and two fellow researchers won an Ig Nobel Prize — dedicated to “achievements that first make people laugh, and then make them think” — for a 2007 study on the evolutionary reasons pregnant women don’t tip over.

Anthropologist Liza Shapiro and two fellow researchers won an Ig Nobel Prize — dedicated to “achievements that first make people laugh, and then make them think” — for a 2007 study on the evolutionary reasons pregnant women don’t tip over.

The joints between the vertebrae also are larger in females and angled differently to better support the extra weight.
