as to the level of genetic science and knowledge the whole of the scientific community is at now, we're like children playing with atomic bombs. the WHO and quite a number of genetic research organizations have been warning of such for years now

There's so much that we don't understand with genetics. Hell up until crispr we were literally just shooting dna segments at cells hoping something would good would result.
But that's that's not going to be very effective for major specific changes.
IMHO people need to stop thinking of DNA like a long list of 'parts' that you can mix and match. You can't add the DNA of bird wings to a squirrel and get a squirrel with wings.


We have a pretty good grasp on gene expression and how it affects certain things here and there... but that's entirely different than understanding DNA as a whole.
The best analogy Ive heard would be... understanding what the buttons on your car's climate control do and how it can change your comfort level. But that clearly doesn't mean you understand how the rest of the car works and why it was built the way it was, and how it was assembled.

Since covid, I no longer think of this as a likely doomsday scenario. Covid was very contagious, yet to this day the number of total cases is less than 10% of the world population... even with a 100% mortality rate, that wouldn't be enough to cause societal breakdown. Not to mention killing the host reduces the chance for a disease to spread, and you can be damn sure humans would take such a deadly disease way more seriously than even covid.
So in my mind, doomsday by pandemic is out. Doomsday by nuclear war still in play!

Covid is just a light scrape. The species barrier and the contagiousness are the big issues there. The virus itself is weak and really overall ineffectual to humans. That 1% mortality rate makes it a joke when it's framed as a "pandemic" virus and is the sole reason why people are even arguing about it in any way.

By contrast, the Spanish Flu had only a 10% mortality rate and no one was making any fucking jokes about that. Yet, the world still didn't stop, jokes or no jokes.

However, you get up into the 30's or 40's percent mortality, there won't be any flouting of that shit, you can believe that. You'd be hard pressed to dynamite people out of their houses at that mortality rate. When 3 or 4 of every 10 people on earth drop like flies, everyone will take that as serious as possible then.

Prior to the one and only EVER survivor of rabies, that is a 100% fatal disease if you don't get the shots and that's why the vaccine for rabies was such a big deal at the time it came out and still is.

Anything those crazy fucks invented in bio-warfare is likely to be a 98 or 99% mortality rate. As opposed to the weak and pussy Ebola Virus which has an estimated mortality rate somewhere between 25 and 90%.

Human immune systems and virus and bacteria are and always have been engaged in a biological weapons race. In the same vein as Space rock collisions, it's just a matter of time.

Yup. And yet still not strong enough to bring humanity down unless they can find some completely new and unexpected way for it to spread, or it won't infect enough people before we start developing countermeasures. It's hard to say how possible that might be in the future, but for the moment I don't believe humanity has the expertise to engineer such a thing. On the other hand we already have immensely destructive nuclear bombs, each of which can erase millions of lives in a matter of seconds. This is where I'd put my money for doomsday, if not on the gradual destruction of the environment.

Ideally, if you have a disease that really can wipe them out. I'm saying I don't think that's currently possible, and I don't know how long it will be until it is. Nukes are already here. Also, even if we're arguing ideally, you don't have to worry about a nuke coming back to your own country and killing all your people after you launch it. You do have to worry about the enemy nukes, though.
 
there are biological germs and viruses totally lethal to humans and have been produced as biological weapons of mass destruction
 
the US has them, Russia, China and probably a number of other nations as well

Yes they do have biological weapons, but you can't just assume they've all hit 100% mortality rates. But for fun, let's assume they have! Remember what I said about infection rates? Covid was very contagious, but to this day has only infected less than 10% of the world population. Even if one of these engineered diseases has a 100% mortality rate, and can spread as easily as covid (which is less likely as killing the host reduces the chance for spread) it still is not enough to bring down any country.
They would need to engineer a method for spread that has never been seen before, that cannot be anticipated or countered by normal means. I don't believe this is possible yet, and I don't know how long it will be until it is. Nukes are here now.
 
tell that to the flea carrying rats that wiped out 2/3 of the population of Europe
 
Thing about biological weapons us they do not need to be that lethal.

For one, getting people seriously ill is worse than killing them, as they require carers, supplies and work, much as seen in Covid -with just a low percentage of really complicated cases- hospitals and supplies collapsed.

For the other you only need to take down a percentage so the basic services go down for lack of maintinance. Once you get the populated places with no electricity, water, food supply and comminications they will basically die with no need of infection.

You do not even need to infect everyone. Just the panic of it is enough so no one goes to do their jobs.

Once a place us like that, it is no opposition for any invassion force.
 
it takes time to come up with a vaccine by that time it could kill billions
 
The US and British military did a study and came to the conclusion, air born Anthrax - 1Bk2 could wipe out a full 80 % of the entire population of central and western Europe in less than 1 week

iteresting because I asked the AIbot chat about donkey and horses ---- it said they are 95% related and yet they can produce sterile mule but we cant with bonobo chimps ---- its because we are not similar enough in the repreductive systems?

No. the ZP proteins are still species specific. They are 'similar' enough to be cataloged as ZP1, ZP2, ZP3, etc... but they are not the same cross species. Gene expression differences between species make for differing behaviors between the ZP proteins and how they behave and what they will interact with.

It's kinda comical how the moment I bring up ZP2... you just repeating it like its some magic incantation that gives you argument support. You clearly dont understand microbiology, so stop making comments about things that you don't understand.
Here's some advice...

1) Put your dick down...
2) Spend some time researching what proteins are and what they do for a living organism.
3) Spend some time researching human fertilization
4) Spend some time reading up on research literature on differing traits of ZP Proteins between species...

After you have done that... then you can talk about ZP2.

I didnt give it any validation ---- i talked about it as a possibility because you explained it is the differences between species and you were not here to expand on that

so if a mere discussion about possibilities and bad reading comprehansion triggers you you are going to be an aweful scientist miss ally

and by the way ---- I asked the AI bot about this, and apperantly you did not explain this well enough maybe take some lessons from the AIbot

chat open AI:
"No, a monkey sperm cannot bypass the outer layer of the human egg. The outer layer of the human egg, called the zona pellucida, is a physical barrier that helps to prevent fertilization by sperm that are not biologically compatible with the egg. The zona pellucida is made up of glycoproteins that are specific to the species of the egg, and only sperm from the same species are able to penetrate it.

Sperm from different species, such as monkey sperm, would not be able to penetrate the zona pellucida of a human egg. This is because the glycoproteins in the zona pellucida are not compatible with the sperm and the sperm cannot bind to the egg. This helps to prevent fertilization between different species, as it ensures that offspring produced are biologically viable.

In summary, a monkey sperm cannot bypass the outer layer of the human egg and therefore cannot fertilize the egg. The barriers in place help to prevent fertilization between different species and ensure the viability of offspring."

and before you say "that exactly what I said you just cant read" --- you didnt... you specificly talked about ZP2 and ZP3 being the main issues while the chatbot says --- 1. there are few barries so more protection for the egg , 2. each sperm and egg have thier own unique "coding" which no other known animals have similar to humans. if you have explained it like that I wouldnt needed to wait untill you elborate on your first comment about this

True cursing is not explaining, perhaps people are just over this topic which has been brought up and hashed to death numerous times over the years.

when i tried to discuss -- something intellegent humans do --- the issue I got also stupid answer except from allyfritz and now tammca which by the way both said non human sperm can be somewhat of a contraceptive due to it flooding the vagina and blocking the human sperm
Click to expand...
Which is exactly what I said with my sperm traffic jam blocking the way comment I said to you.
danzuna said:
and in my question to you i asked specific things to really hear your answer because you seemed atleast at the first massage someone to be able to have back and forth
Click to expand...
A back and forth requires both people listen to the other's answers carefully, I answered you at 3 very distinct points on the clock, I may not have been as awake and attentive as I could have been on my part if I've missed an actual question you were asking that others had not already answered I'm sorry for that.
danzuna said:
then we got about the egg barrier which ally explained there ZP's are not suitable from a dog -- fine, then i went to the AI chat and borught the list of the most similar animals in condition which all the contraceptive pills women take are based on expriements on them so yes it sounds interesting that if you take medicine based on them then does thier sperm passes the egg barier
Click to expand...
No their sperm does not pass the egg barrier. As others have said some species are similar but none of them are an exact match for a human as far as getting past the egg barrier. (This is where people were getting frustrated with you, as it is a point many have made, some not as politely as others.) Some forms of contraceptive have nothing to do with the egg at all, they work by killing the sperm or making the environment the sperm has to travel through harmful to the sperm. So testing such things on primates for example is valid because their sperm are similar enough that what works on the sperm of that species will also apply to humans. Anything that also coats or blocks access to the eggs outside can also be tested for this reason. But the testing is not being done on these species because their sperm can penetrate into the human egg.

danzuna said:
--- this for example is not something that was answered nor discussed previosuly totally based on the topic and science nothing "dellusional" about talking if there is a possible animal that can pass the egg barrier if all our medicine is tried on some of them (apes,monkeys, roudents)
Click to expand...
I guess the problem is on the one hand you seem to want real world answers, but when people say no it can't happen it suddenly becomes hypothetical "well what if it could happen, would it kill the egg." Contraceptives is BIG business you better believe sperm from many different species has been investigated for compatibility and thus provide good test subjects to be exploited by humans.

So hopefully you consider my response respectful enough for you this time. As it is the last one I'm making on this topic you're discussing.
Another species sperm is not getting inside a human egg, without intervention by a human in the process.
If a new species is discovered in a tiny valley somewhere as yet not known by human kind could there sperm be the magic bullet? Maybe, but till that happens you have the answer about human eggs and other animals sperm, it's just up to you if you want to accept the answer or not.

Have a nice day, and if you want to take up a career in biology and prove us all wrong by all means I encourage you to do so. You never know what amazing thing you might discover along the way. After all penicillin basically came about because somebody was slack cleaning up their lab and mould grew in a petri dish. :gsd_wink: Although I've always thought Fleming should have discovered something related to the lungs and respiratory system with a name like that.

My money is on doomsday by human stupidity first and foremost. The actual tool is just yet to be determined, either we continue to slowly destroy the very environment we need to live or we blow our selves up, it really all works out pretty much of a muchness in the end. Unless we as a species come together and just stop and think.

no one was pointing it out to me... they just cursed or said "dog sperm can impregnante human egg Stupid" -- which i wasnt even talking about pregnancy i was talking about only passing the egg barrier - so not my fault people dont read because they already want to write something snarky
you write that primate sperm can penetrate the human egg ---- the AI chatbot i used said it cant because although very close DNA they are not the same in the sperm and egg issue ---- whats your opinion?

I dont see issues with talking in theroy discussing different options --- and ofcourse i personaly dont accept just "no" if I want to know more about the subject (which again - it wasnt just a "no" it was "WHAT ARE YOU HORNY AND STUPID OR SOMETHING??" which is BS response)
