There is also the mitochondrial DNA which is probably placed in the most unsafe environment inside the cell.

Mitochondrial DNA needs to be in the mitochondria, presumably because of proximity and/or latency issues. That's why the vast majority of mDNA has moved to the regular DNA or simply disappeared. The stuff that's left behind isn't an accident.

So, this is the so-called "intelligent design"? I think not.

Just to play devil's advocate... It almost certainly is intelligent design, because it's intelligent given certain constraints (the existing gene pool in a given generation, and the fact that something working is better than something theoretically better but doesn't actually exist). God iterates using an Agile process.

All evidence suggests God is an adherent of the Worse is Better design philosophy.

I'm glad you bring that up, because these are the kinds of things you should cite to refute someone claiming that biological life bears the signs of an intelligent designer, supernatural or otherwise. What distinguishes intelligent from naive optimization is the ability to refactor instead of just making local improvements. Unfortunately, there seems to be a trend toward refuting IDers by claiming that the very prosp…

I believe you're wrong. Take german and french cars. One of them, won't say which, are better designed than the others. To say that a plan is NOT designed because it's flawed is like calling names on a programmer because he uses Java.

You don't refute ID by showing some sub-optimal function in an animal body plan, firstly because ID doesn't claim everything is optimal. ID implies intentionality, but does not and can not explicit intentions. Anyone can make an object that by all means can not be the product of a natural phenomena, and still someone else being able to tell it's design, could not really tell the purpose of it. And, of course, if function is obvious, there's also a better solution.

The "unscientific" argument is used because the "we are horribly designed" argument has been done over and over again and ID proponents just dodge it with nonsense about how it's all due to The Fall of Man or whatever. It's not like they don't know about these problems, or nobody ever told them. They just don't think it disproves their ideas. They're offering an alternative explanation that matches the data, but prov…

Darwinism is also full of "x happend differently than previously thought". Any theory is allowed an must adapt to new data. It's not like you're explaning a dozen of particles to which you add a new one every two decades or so. The domain of the theory shapes the theory.

Like someone playing a piano concerto with 10 fingers. That's such a terrible design. Dawkins would have made the humans with 12 fingers.

So, this is the so-called "intelligent design"? I think not.

Sitting on my desk right now is a long-handled object with a heavy mass at one end, just like a hammer. But the heavy mass pivots in relation to the handle, the handle is ergonomically crafted in the opposite direction from a hammer, and it's covered in buttons. If you try to evaluate the design as a hammer, it's obviously a terrible design -- but it's a pretty good joystick (good enough for me to use, as the 12th best Descent pilot of all time [0].)

What can we say about a designer from just looking at their design? Not much, if we don't understand what their design is for. If we're guessing at intent or guessing at design constraints, there's very little useful we can say, pro or con.

What do these 'hacks' indicate about the Intelligent Designer(s) in charge of human creation? That is, can we, as believers in Intelligent Design, discern anything about the Deity(ies) who did the design? The obvious question is: "how many deities did the design? One or more?" After that, you'd move on to gender, and other indicators. Ultimately, one would hope to be able to have Scientific Proof of the truth of one…

Yes, you are just dreaming.

Mother Nature is not, and has never been an engineer. Evolution is trial and error. DNA is spaghetti code of the highest order.

Highest order indeed. There is even a very neat scientific article that compares the call graph of the Linux kernel with the "call graph" of the E. Coli genome. The E Coli genome has incredible amounts of copy-paste and legacy code :)

My personal favorite poorly designed part of the body is the sinus cavity. When we used to walk on four limbs, our heads would naturally incline to an angle that allows full drainage of the sinus cavity. Now that we walk upright, there's a dead spot in the back of the cavity where mucus and bacteria can pool. This is why if you're experiencing sinus pressure but you haven't reached the stage where nothing in your hea…

Always wondered why after surfing the water didn't drain out of my sinus until I bent over to pick something up. Thanks for the insight!
