Unusual technologies

Interplanetary? How??? It’d be cool but how would that happen, it’s not like the species could get 50% of their “body development control genes” from one species and the rest from the other, even if those existed in a useful way (that sort of thing does exist but the stages of growth are too involved you messing with them would kill the creature as a fetus) the proteins, neurological, and digestive systems would have to be integrated and they’d prolly use incompatible everything for those. Not to mention immune, respiratory, and most of all actual practicality. Bird wings are useless on a human and human arms are useless on a fish and will kill an ant somehow.

A lot of the same issues would apply in biomechatronics, yet that concept is obviously plausible. What is the big difference with combining different biological systems?

I would assume she is talking about the use of different kinds of enzymes/proteins for the same jobs, different ways the different bodies would relegate certain things, etc. and how those might be incompatible with one another

No expert tho lol obviously

Why would that be an issue? Having multiple systems doing the same things could only be a benefit. And if the proper conditions for each species are incompatible, why can’t one (or both) of them be changed?

theyre… highly incompatible. look into fetal development, everything happens in a very specific order, in very specific ways, and it’s tied to hundreds of millions of years of evolution. every species alters it a little, even humans and chimps have some differences. imagine the differences youd get if your biochemistries ran on different principles. every fetus would develop like a blob. yes, you could find a mix that “works”, but it would just be a blob that doesnt come out a miscarriage. yes, there is a fix, entirely making your own fetal development process, and a biochemistry inspired by the creature you want to hybridize, but that isnt hybridization, thats playing God to arbitrarily make new animals, which arent connected to the originals, just based on them. closer to the difference between the US and Rome than the deep south and Liberia, if you get that youre a nerd by the way.

Yes, different species have different developments, and more different species are more different in their development. If we apply this to different biochemistries, the differences would be so great that the two systems wouldn’t interact at all. All they’d need is a few translator proteins to ensure that things go in the right place, and they’d be set

not proteins. general bodies. they’d just be blob miscarriages plus nonsensical proteins

Why though? They have all the right proteins, and there are no unwanted signals going across, so what is the issue?

The tissue development?

What is the issue there?

You mean…what is the “Tissue” here?

heh…heh…

This is the issue. Kinda sucks when you describe the problem and the other human just says “well you could theoretically fix the proteins with these unexplained translator proteins” and ignores the rest.

This is exactly the problem with underwater and other really pointless discussions where the proponents always go “but wait what if they could use the INSERT RANDOM THING to do THE THING?” whenever their last really shaky argument is torn apart.

There isn’t much of an issue with the tissues themselves. Sure, they’ll need extra proteins to link together distinct cell lines, but other than that why can’t it just work as normal?

Here you go. I quoted it so you could read it. It’s also Imperfect so I’ll explain again. Take, a jaw. In mammals the zygote becomes a blob, elongates, gets some foldy stuff that looks like gill, gets a mouth, and then an anus. The gill-like things become the jaw bones, and three ear bones of the animal. The ear bones are involved because ancient tetrapods heard with their jaws made of four bones each, but mammals evolved specialized ears out of the bones associated with the joints.

In contrast an ant just grows some spikes off their skin to bust out of the egg and after being born develop little leg things, some of which fold into mouthparts. Also in ants the hole that develops first is the anus, and the body plan is subtly flipped upside down.

Imagine both of those happening at once. On one half would be tons of ant legs , lots of them trying to fold into various body parts but other stuff getting in the way, and on the other there would be a bunch of foldy structures trying to become jaws and ears but getting immobilized by the proto-exoskeleton and opposite that on the same side the mammalian tailbone would be preventing the ant genes from folding their legs into a freaking mouth on the creatures butt. Remember: ants treat hole a like an anus while mammals treat it like a mouth. Same with hole b but reversed. No digestive system is going to survive developing in ten way and four directions at once.

You probably also couldn’t splice a human and a car into a functional cyborg, yet I doubt this example will make reconsider the possibility of biomechatronics

In the same way, it’s not very coherent to claim that because two very specific taxa currently have incompatible development systems, the concept of this chimerism is entirely impossible. Even this scenario (which has been exaggerated, ants and humans develop on the same body axes), it should be entirely possible to manipulate the timings and positions of various traits to allow proper development. This would be even easier for alien biologies, where the specific parts are independent and have no natural crosstalk between systems

…DID YOU READ MY ORIGINAL THING? I am seriously beginning to question your ability to read, like for real I just said this.

To hybridize a human and an ant you’d either splice the eye and exoskeletal genes from an ant into a human and construct artificial organs for any other issues or implant human-like lungs into an artificial-ish ant to allow it to be molded into a more human-like body shape. I’m fine with that, but I don’t think it’s mixing species, just making something that looks like a non-problematic mix would if it were possible.

So it’s possible to do something else. Why is this such an issue to my idea? It is entirely within reason that two processes with similar-looking results can both be possible

I was arguing against mushing together totally unrelated creatures, not making something that looks like an idealized hybrid. I’m totally fine with that. I wasn’t aware you were arguing for anything remotely like hybridization, I thought you litterally meant “you take some genes from this, some from this, and troubleshoot it a little” not “let’s see how we could make a man-ant, even if it’s 0% human or ant”

So what is your argument against true hybridisation? I haven’t heard anything besides that the worst-case scenario for hybridisation doesn’t work out of the box and that other processes have a similar looking outcome
