Unintelligent Design: How Come Men's Testicles Can't Do What My Parrot's Testicle Can?
All birds including my parrot carry their sexual organs internally. Most don't even have a rudimentary cock, if you'll excuse the pun. Some waterfowl have a pseudo dick, but most birds manage just fine cloaca to cloaca.
In certain species, some dual internal organs have been reduced to a single functional organ for survival reasons. Snakes only have one functional lung. Parrots only have one functional ovary or testicle. In female birds, sometimes the smaller, dormant ovary will start functioning if something happens to the other one. Male parrots have one functional, entirely internal, testicle and no one-eyed trouser snake. If I remember correctly, a parrot's body temperature is maintained at around 102 degrees Fahrenheit, which is much hotter than the body of human being, yet the sperm of a human being can't be produced at 98.6. It needs a cooler region.
Why can't men do that? Those two glands are exposed and tender. Every male learns early on to protect his nether regions. Can you imagine trying to do that while flying through a rainforest? Oh shit...kapok tree...whoops...shit...vine coming...damn...fuck! That was a stupid place to put a vine...HOLY CHRIST IS THAT A HARPY EAGLE...OH MY FUCKING GOD!
And scientists: why is it that my warm-blooded little dinosaur can produce sperm internally at a high temperature? There has to be a really interesting evolutionary adaptation story here.
