Intelligent design is part of creationism which is a counter argument to evolution. Its belief is that we were designed and created by a god-like being in our present form including all plants and animals and states that species cannot become other species. Many feel that this different opinion should be taught in schools so that students hear both sides of the argument. Currently it shouldn’t because right now it’s more like “Unintelligent Design” since it has no concrete facts for it and many facts against it.
With the belief that we are made how we are and haven’t changed or evolved from earlier organisms, there are a lot of holes intelligent designers try to fill. They commonly use the watch analogy where they point out you can tell the watch has a maker and wasn’t created by some random chance because of its complexity. This is a bad argument since watches do not grow, reproduce, or have any biological functions. If there truly was a creator then they messed up from the moment we were conceived.
We know biologically that when a human embryo grows that the default sex is female and uses that as a blue print until around 6 weeks. At that time sex is permanently determined depending on if a X or Y chromosome fertilized the egg. If a Y chromosome fertilized the egg, then all the female stuff disappears and the male stuff kicks into action. This is also why babies can be born with both sets of reproductive organs which a creator should know how to prevent. The nipples remain even if the fetus ends up being male because of the original female blue print.
Nipples aren’t the only issues we have, including the rare third ones. Vestigial organs stick around because they were useful in earlier stages of evolution and haven’t fully disappeared yet from us. There was a point where human-like apes had stubby tails and by our time we no longer need them, however occasionally a baby is born with a useless tail because of the genes randomly firing and bringing back features we no longer need.
Another intelligent design mistake, but evolutionary explainable feature, we have is the laryngeal nerve that goes from our brain to our larynx which holds our vocal cords. Instead of going straight from brain to our larynx, it goes down to our heart, under an artery, then back up to our larynx. It had a more direct route in our ancestors traveling from the brain, past the heart, and to the gills. In giraffes it can be 15 ft. (4.6m) long going up and down its neck. Nerves like this aren’t the only mistake or leftovers from evolution.
Animals like snakes and whales have bone fragments similar to hip bones which are useless to them, but at a point previous in their evolution they did use them until they lost legs. When sea life reentered the ocean it formed animals such as whales, dolphins, and sea turtles. They never reacquired gills since they simply continued to surface for air. If intelligently designed shouldn’t all sea creatures have water breathing gills?
Teaching such flawed science would be a disservice to our children and opening up possible teachings such as flat earth theory or even geocentric theory. Currently evolution stands up to tests and reason, and if we did have a creator, either they were stupid, or made mistakes on purpose.
