The back is a good one. How about this design where you stuff food in the same hole you breathe through? Seems so unnecessarily dangerous.

    Its worse for Squid their brain is a torus shape with its esophagus running through the middle. their brain cannot stretch but their esophagus can making it so that if a squid were to swallow to large of a bite it can rip their brain.

  Sure, but that's another hack. Evolution's solution: cough it out Better solution: don't send food, water, and air down the same pipe in the first place I mean, no competent engineer would design the plumbing for a building such that the same pipes were used for water and air at different times, right?

    a software engineer would. we call it "multiplexing".
  - ekianjo 5y ago
    No its not just cough it out. The mechanism to avoid food and fluids is a lot more complex than that.

    That reminds a bit of systems where the data plane and control plane are the same. Like the old AT&T phone network.

  I've read that urination actually helps by cleaning out the urethra after ejaculation, though, stopping some diseases - which some people think might be why men have the urge to pee often after sex. So it may not be as evolutionary crazy as one would think

    Same for women... "In every final scan we could see a big, full bladder, even though most of the women went to the toilet before they went inside the MRI,” explains Pek with comical astonishment. “We think it might be evolution’s way to force women to urinate after sex. Perhaps our ancestors developed this function to avoid urinary tract infections, but that’s only a hypothesis." https://www.vice.com/en/article/qvgkzw/the-story-of-the-dutch-couple-ida-sabelis-pek-van-andel-sex-intercourse-mri-scanner-for-science https://www.vice.com/en/article/qvgkzw/the-story-of-the-dutc...

You need mucus and it's a lot more convenient to dump it down the throat where it can pull double duty as lubricant and be recycled than have it come out the front all the time.
