The only possible exceptions I can think of are fish(I imagine gills and mouth are not connected but don’t really know). I am excluding bacteria and viruses and I believe they don’t really breath(correct me if I’m wrong).

    I’d have put the vocal chords in the nasal passage, allowing humans to still talk while eliminating the choking problem.

    Exactly. A very simple correction to the design would allow for both.

    The laryngeal nerve is a great example of how flawed our bodies are. A few more are:

    • Our back is terrible for walking upright. It evolved as a horizontal support and doesn’t work well when compressed.
    • Our hips are too narrow for the size skull we give birth to. Many women die from this without healthcare.
    • Our eyes suck. A lot of people need corrective lenses from a young age. This gets even worse as we age.
    • Speaking of eyes, our retinas are backwards. The nerves that send the signals back to our brains run in front the receptors that pick up the light. We have a blind spot because those nerves need to pass through to reach the brain.
