This is the Dell laptop I have been using for several years. The blue arrow points to the extended battery. It sticks out from the machine as if the designer had forgotten about it at first and needed to bolt it on later.
When I turn it over and take out the battery, it looks like this. Apparently the machine comes with a regular battery that does not stick out, but nobody buys it, because it does not hold enough of a charge. Our company has several dozens of these.
Not only does it look ridiculous and ugly, Dell even had to redesign the docking station so one or the other variety of battery would fit. You’d think the designers at Dell could come up with a laptop and a battery that was integrated, fit properly and did not look like an afterthought.
Steve Jobs of Apple would never have tolerated this. I would venture to say that Apple is Apple precisely because design matters to them.
Mammalian testicles are like Dell laptop batteries. They don’t fit. They hang outside the body like a botched design. Just look at most mammals and their ugly testicles. Start with farm animals and dogs. Rats drag their testicles behind themselves on the ground. How did this happen?
It turns out that sperm production is very sensitive to temperature, which can’t be controlled very well inside a hot-blooded body cavity. Most of our mammalian ancestors eventually dropped their testicles outside the body ostensibly to give more control to temperature regulation. Male readers will know that testicles hang very loose when it’s hot, and they are pulled up close to the body to get them warm when it’s chilly. To quote Elaine in Seinfeld: “It shrinks?”
In one way, it’s a pretty good design. In another way, it’s ugly, looks like an afterthought, and leaves the jewels exposed to injury, both by attackers and by accidents.
While this is a problem for many male species of mammals, I am most familiar with humans, and therefore will illustrate here how the descent of human testicles from inside the body to the outside represents a design flaw.
The diagram above shows an outline of the male human reproductive organs as they are now. Note how the vas deferens loops over the ureter and back down to the prostate. If I were designing the male anatomy, I would not loop the vas deferens over the ureter like this. I would shorten it a great deal and bring it directly from the epididymis to the prostate. How did this happen?
Here is a version that I marked up to illustrate my point. The testicles were originally inside the abdominal cavity, somewhere up where I marked it with a blue bubble. Then they gradually, over millions of generations, dropped down. Unfortunately, rather than dropping in front of the ureter, curving down along the green line, leaving the ureter behind, they dropped behind the ureter, effectively making a wrong turn. The vas was left with no choice but get longer and longer, causing the odd design we have today.
Would an intelligent designer, a God, creating man in his own image, have built man this way? I think not. Like many other design flaws in the human body, our testicles are a remnant of our evolutionary heritage.
And now you know what human testicles and Dell laptop batteries have in common: Lousy design.
