I know I’m a little late to the party… but if you’re still answering questions:
Do you know why we are born with two kidneys, if we really only need one? I’ve ready through all your answers here and it sounds like you have no decreased life expectancy, no real limitations to activities/foods, don’t feel different, don’t have any side effects. So I can’t help but wonder why the human body has evolved to have two kidneys if we just need one? Plenty of other organs we just have/need one of (pancreas, liver, etc). Is it “vestigial” like an appendix (I think they still haven’t found a use for that?) or backup or important for some people or in some instances?
Any thoughts?!
