It may be that forcing us to include vitamin C in our diet does make for healthier humans in general - but why then have the remains of a clearly once-functional gene for VitC biosynthesis present in our genome? If lack of VitC synthesis is the goal, why not just exclude this enzyme from the genome all together? Why have evidence for a previously functional version (in the same genomic area as in other mammals)?

I had the same answer when we discussed this at RTB (I am a volunteer apologist there). No enzyme to create vitamin C means a healthier diet is needed. I still haven't seen a good reply, except that because the gene doesn't work it must be "broken".
