While you don't actually have to worry about this one anymore, it still may be disconcerting to think that the penises of our ancestors were lined with a hard spine.
A 2011 study published in Nature compared the human genome with that of some modern primates to find the specific genetic deletions that makes humans who we are. While the study found 510 deletions responsible for immensely important things like increased brain size, perhaps its the deletion of that spined penis for which we're all most thankful.
