Quote:That is true as far as it goes but the same basic forms keep popping up in the fossil record (dimetradons are basically wolves with solar sail fins instead of fur. Which is why the function of the creatures can pretty much be guessed on sight. The problem is that genetics have little effect on the shape... the niche in the eco system has far more of an effect. Earlier in the mentioned the closest genetic relative of a bear being a pig or a shrew (details dimmed by time), thats why two things that look alike cant necessarily breed.
We know enough about terran biology to have a pretty good idea what it can adapt to. The claims I'm making are on a par with saying fast swimming fish will be streamlined, dictated by principles beyond dispute.
Quote:Because injecting random chemicals into your bloodstream is so healthful. Fine tuning only has so much effect. If it kills you by thinning the blood for the point it cant carry oxygen, you are dead. If it causes the platelets to spontaneously congeal, you are dead. If it messes with the rhythm of your heart, you are dead. If it bonds with the copper in your blood, you are dead. If it effects your skeleton so it decalcifies and you collapse on yourself and then suffocate your dead. Necrotizes your flesh, you are dead. Randomly fires your neurons till you starve to death, you are dead. Exotic toxins are more likely to kill you, as your ancestors didnt lose the ones that cant survive it.
And, of course, none of the alien toxins will be fine tuned to affect terran biochemistry, putting severe limits on their likely effectiveness.
Its a matter of dosing. Yes, we can use tiny little diluted doses of some of them. Yes, food poisoning can be sold as a beauty aid. Arsenic was used as such and yes 1% of a blowfish or so can be eaten However youre changing the subject.
We are discussing if adapting the biochemistry would make them unable to crossbreed. Which I bought up toxic bodily fluids all youve done so far is confirm that toxic bodily fluids exist. However if a human offshoot doesnt have a compatible system they cant breed.
To this end I point out that 93 degrees F is the temperature that sperm multiplies at thats why hot tubs and conception are a bad combo. The sperm get cooked. The same is true with the wombs acidity sperm can only live 3 days in that environment max they come in an alkaline fluid to extend there chances. Genetic viability only matters if the sperm can reach the egg. Yes, dead sperm works for conception, but we arent talking with mechanical help here. I also doubt that nekojin have a strong internal current to shoot the sperm in bullet style.
I could also go on about conflicting genetic construction orders involved or if the offspring is likely to survive inside the womb do to the chemicals fed to it. For instance, to make a human embryo male a certain chemical additive must be present at the right time or the offspring is female or intersexed or something. This is just one of the chemical issues involved. Thats if the womb isnt requiring adaptation to some random element that is absent or present in the food adapted to. We are also talking about a child that is getting instructions to build to radically different types of ears. Which would mess with their hearing development. Which is why I suggested a higher number of non-lethal birth defects.
It is nifty though I only counted 5 connections.
