    The extreme detour of the recurrent laryngeal nerves, about 4.6 metres (15 ft) in the case of giraffes,[32]: 74–75  has been cited as evidence of evolution, as the nerve’s route would have been direct in the fish-like ancestors of modern tetrapods, traveling from the brain, past the heart, to the gills (as it does in modern fish).

      Intelligent design. Same with our eyes 🤣 just put them in backwards and thread the cables through the retina; genius. Octopuses are clearly gods chosen “people”.

        The intelligent design geniuses argue that the eye is too complex to have evolved.

        “Of course it didn’t evolve like that! It started with a patch of light-sensitive cells and worked it’s way up from there. And that’s happened more than once.”

        They have to think evolution means that creatures and features popped into existence fully formed. Not only because that’s how the Bible tells it, they can’t comprehend evolution on a 7,000-yo Earth. And neither can I!

        You’ve got the killer argument though. “Why didn’t God bother to make our eyes like he did with the octopus?”

              His theological understanding of pokemon was convoluted at best, haha.

              He swore up and down that pokemon trainers were witches, and the pokemon were demons they could summon to act as their familiars, and their evolution was symbolic of how much satan’s power had corrupted the vessel.

              Like, he thought you started with a mouse, then summoned a demon into it and bound it to make it your familiar, turning it into Pikachu. Then as Pikachu evolved into Raichu, that was a sign that satan’s power is further corrupting the poor mouse, one of god’s creatures.

    There are a few flaws with that in reality. One is too much risk consolidation. Having every artery in the same place means that it’s a very easy target for animals or other humans. Another is that it requires far more complexity to actually distribute resources isometricly relative to their need. It’s also easier for disease to grow tumors in a giant mass of blood vessels since they are very homogenous. Another downside is that heat is not distributed evenly so it greatly increases the amount of energy that has to be spent on building auxiliary blood vessels which means the animal has to eat more to achieve the same reproductive success.

    Life in reality is balancing many things. Thermal efficiency is a big one, material efficiency is another. Defensibility is a big one, and also genetic simplicity is another. Your body is procedurally generated, not created from a blueprint really. Cells create structure via functional logic in large part, although there are hox genes which encode some basic directionality and relative spatial cell differentiation based on its neighbors and the proteins they are presenting on their membranes.

    In other words your body is generated more like a Minecraft world and creating very clean wiring and tubing even if there was pressure for it, would be something that would require a ton of genetic complexity. More complexity means that every single cell has to copy these extra hundreds of genes whenever it copies it’s DNA, which raises the overall thermal and nutrient cost linearly. This is the reason people are beautiful on the outside but on the inside look very strange. We do put many of our evolutionary resources into beauty but not in places where it will likely never be seen.

      Actually I was master debating myself which way to make the meme.

      Both seem funny & inaccurate.

      What I posted hints to random design without neatness as a priority, yet facilitated necessities in regards to environment (you know, evolution).

      The alternative validates how stupid neat cable management would be:

    Are those zipties? I fucking hate zipties whenever cleaning out old installs. They’re just about always so tight it feels uncomfortable to cut those when youre dealing with fibres or just about anything, really.

    I use velcro ties myself most of the times. If I absolutely have to use zipties, I leave then so loose that they’re just guiding the cabling, not choking it.

    Just today I cleaned out one +15 years old install and oh boy, multiple zipties there. Awful

      Use dikes, not a knife, and cut the head of the tie, not the strap

        YES

        Flush cutters specifically. And you cut the side of the head opposite the tail with the cutter flat against the face of the tail passing through the head.

      Exactly. Let’s use a securing mechanism that requires a razor-sharp blade, held perilously close to what you don’t want to cut, in order to undo.

    I think the funniest part of this post is the nightmares people are getting from zip ties.

    God wiring his new creation: … oh yeah I need a cable for the heart … oh yeah, I need a cable to power the lungs … oh yeah, almost forgot, need a cable for the liver … oh yeah, need a cable to control the legs … oh yeah, need some sensor lines for the hands … oh crap, wired the genital sensor lines wrong … oh shit, no more room for the lines for the kidneys, maybe if I wire it this way … shit, need more power lines for the stomach … crap, need more sensor lines here … shit, shit, shit, I need more power lines

      shit, forgot to install a valve in the heart … and ofc I now have to take it all out just to get to the heart, right when I got the wiring all nice & neat, ffs

      They show up in the worst places. Top offenders are inside A/C units and car engines. Yanno, where there’s lots of vibration to help the little bastards cut through insulation.

        Huh… Cutting insulation is a new one for me. I’ve seen it with adel clamps that chewed through their grommet but never nylon.

        Were they in areas where the wires needed to be allowed too mice but were too constricted?

          I had a domestic A/C unit fail this way. Zip ties kept the power leads to the compressor taught against the bottom leg of the compressor housing (cast iron or some kind of steel). The edge of the zip tie, combined with vibration and moisture abraded the insulation over the period of about 3 years and grounded out against the housing. This destroyed the compressor motor windings (melted to a dead-short under power), leading to a pricey repair.

          Technician knew what to look for since he saw the exact same failure mode on that make of A/C unit in a commercial model on a rooftop.

            Damn! Yeah with the vibration and start torque that makes sense. Sounds like it didn’t have strain relief? I imagine if the wire is cheaped out on at all by the manufacturer it could be more prone as well.
