text: what did god have against humans, other primates, guinea pigs and some fruit bats? humans, apes, guinea pigs and some fruit bats all share a disability.  they are all unable to biosynthesize ascorbic acid (vitamin c).  other mammals can do this so why not us and these others?  lack of ascorbic acid results in an afliction called scurvy which causes you to bleed from the soft membranes in your mouth and *other* parts and ultimately results in death.  the gene to code the enzyme responsible (l-gulono-γ-lactone oxidase) for synthesis exists in humans and other primates, as it does in other mammals (except guinea pigs), but it is damaged or disabled so it specifically cannot do anything.  so why would god do this?  is it a result of original sin?  why did he specifically only give this disability to a select group of mammals? obviously, dog also subsidizes farmers by ensuring the need to grow tomatoes and oranges, and plus he needs to keep his catholic flock employed enough (migrant fruit pickers) to not convert and, more importantly, to tithe.
