I remember she took two groups of lizards and one group was allowed to eat fecal matter and the other not. They weren't fed the fecal matter as a diet, just allowed to at first. Over time both groups were set up and fed the SAME diet and the ones that ate the fecal matter grew at a surprizing rate compared to the group which did not. I would imagine it has to do more with being infected with needed pathogens than anything else. I believe she made this very clear in her paper. Later I intend to review it myself...thanks...TC
