Rosemary, I looked it up..... not sure if this is accurate, but it makes sense: the gallbladder stores extra bile to help with digestion. Because our transit time is so much shorter than normal, we don't need as much bile, and failure to empty bile out of the gallbladder properly is listed as one of the causes of gallstones.
