Next time you’re annoyed by hiccuping, blame your ancient brain stem and amphibious ancestors.
In his new book, Your Inner Fish, the head of Chicago University’s Anatomy Dept Neil Shubin contends that hiccups are caused by impulses sent from your brain stem to a partially ‘remembered’ gill structure.
This evolutionary throw-back is just one of many that Shubin uses to highlight the random outcomes of evolution and counter the assertions of intelligent design proponents. No intelligence in its right mind would lay claim for responsibility for the oddities illuminated in books like this!
