Real Human-Animal Hybrids! Shocking Pregnant Chimpanzee With A Human & Mouse With Human Brain!

When thinking of human-animal hybrids the first thing that comes to mind for most is the idea of some sci-fi film or novel. However, what if those experiments turned out to be real? It can easily be assumed that there are many things that government scientists are working on that are top secret and people aren’t supposed to know about them. So why shouldn’t the creation of human-animal hybrids be one of them? After all, in the past scientists have already attempted it and had some surprising results! Just hose close did they come to making a living hybrid? And what problems would such a feat bring with it? Read on to find out!

Half-Human Pig?

Back in 2004 scientists at the Mayo Clinic in Minnesota had made some steps towards human-animal hybrids, as they injected human stem cells into pig fetuses and successfully created the first pig with half-human blood! Now the purpose of their experiment wasn’t to create some creature straight out of a sci-fi movie but simply to see how human and pig cells would interact when they were fused together. Their results showed that some of the cells had stayed separate and their new chimeric hybrid creature in different parts of its body had either purely human and purely pig cells. However, some had fused together to create DNA that they had never seen before. While their creation on the outside looked like a normal pig, on the inside it had half-human and half-pig cells. What surprised them the most, was that the animal had a type of blood that was never seen before and which was made as a result of the mix. They had hoped their experiment would help them with xenotransplantation, which is the use of animal tissue and organs in humans, to fight diseases such as HIV but unfortunately, they had found the hybrid had the porcine endogenous retrovirus, which is present in all pigs, which would cause problems with xenotransplantation. It is unknown as to what happened to the pig hybrid they created. But what other experiments were created to help in the field of medicine? Read on to find out.

Pigs & Sheep With Human Organs?

Of course one of the main reasons to create such hybrids is to further the medical field and as National Geographic reported on one case, to create a farm of animals that can be harvested for human hearts and lungs. As controversial as that may sound, it is a major field of science in the US with one of the leading scientists working on the project being Hiromitsu Nakauchi who works on this in a lab in California as such work is illegal in Japan. And to prove that his work is encouraged in the US, the Army had given him a grant of $1.4 million. In 2017 they had created 186 embryos for a pig-human hybrid and they had also worked on creating a sheep-human one. Though there is a catch. Their creatures are only allowed to develop for 28 days before they’re destroyed. They are still mostly animal than human, with only having 0.01% of human DNA. However, as Nakauchi admitted, it isn’t enough to make a creature with human organs but it’s still progress and they’re getting closer every day.

Goats And Cows Producing Human Milk

But pigs and sheep aren’t the only animals to be experimented on. In 2009 a team of Russian and Belarusian scientists had successfully genetically modified goats to produce human breast milk. Well, maybe not 100% human milk but they were able to fill it with human cells, creating milk that had 60% of the lysozyme and lactoferrin that characterize human milk. However, they weren’t the only ones who did so as not long after a team of Chinese scientists made a herd of 300 cows that produced human milk. But why? Well, the goal of both teams was to get human breast milk on grocery store shelves, hoping they could harvest human milk on an assembly line, being sure that people would flock to the stores to buy some for their families. The Russian team had even advertised that its human milk made delicious cheese! The Chinese scientists had originally planned to have their product in stores by 2014 however their product was not met with the enthusiasm they hoped for and so their plans were pushed back. But how successful were experiments on smaller animals? Read on until the very end to find out!

Mouse With Human Ear

Without a doubt, one of the best-known human-animal hybrids technically wasn’t one at all! Though it would have been if the experiment had gone through to the end. The experiment in question regards a mouse with a human ear on its back that was bioengineered by a team of Harvard and MIT scientists in 1997. They had put a scaffolding in the shape of a human ear inside of the mouse that was made of biodegradable materials. Slowly, it was absorbed into the mouse’s body, making it an actual, biological ear of cartilage that theoretically could have been surgically removed and grafted onto a human being. That was their plan after all. To find a way to help plastic surgeons who had a hard time reconstructing human ears. Though before the researchers could progress to human trials, to find out if such a thing would be possible, their project ran out of funding but its leader insisted that he could still pull it off if he could just secure “roughly another million dollars in funding”.

More Mouse Experiments

Though where mouse experiments are concerned there had been some other controversial ones. In 2010, researchers at the Salk Institute created a mouse with almost entirely human liver and then proceeded to inject the animal with every disease they could. But once again the goal was one to help advance the medical field. This time their goal was to run experiments on diseases like malaria and hepatitis B and C that can only affect humans and chimpanzees. In the past, they had done such experiments on chimpanzees but decided to this time do them on mice in hopes of avoiding complaints from the ethics board. Once the mice were injected, the researchers then had tried to treat the illness believing that this could lead to a new breakthrough in medicine. A year later, another group of scientists had grafted a human anal sphincter onto mice, complete with human nerves and muscles. They were delighted to see that they generated their blood supply and fused the rest of the flesh when grafted onto the animals’ bodies. The reason behind this, as with most cases, was to advance medicine. Though if you want to know more about other horrific experiments and how close scientists are to making an actual human-animal hybrid, then be sure to read on.

Mice With Human Brain

While animal rights activists would find any of these experiments on animals horrendous there was one experiment that made many question the ethics behind it. Back in 2014, a team of researchers had given mice millions of human brain cells by replacing the mouse ones with human. They had changed things so much that they only left the mouse neurons intact and once inside, the human cells completely took over their brains, blurring the line between human and animal, like never before. Their reason for this was not to mimic fiction, like Pinky and the Brain, but to advance our understanding of human brain diseases by studying them in a whole mouse. Though where things get a little bit controversial, is what they did as in their main experiment, the researchers played a noise before attacking the mice with an electric shock. They did this in order to measure how the mice reacted the next time they heard the threatening sound. And while to many that sound terrible, it did show researchers that the memories of these modified mice were four times stronger than those of a normal mouse.

If the previous examples of human-animal hybrids seemed like nothing to you here is where things get even more controversial. One of the most questioned hybrids, in terms of possibility, has been the humanzee. Already in the 1920s Soviet biologists had taken attempts to do so but never succeeded. However, if two Chinese scientists are to be believed, China had nearly made the first hybrid decades earlier. In 1967, they had come close to creating a human-chimpanzees hybrid and according to them if it didn’t get shut down they would have succeeded. But how would you create such a being? Well, the two men from Shenyang had claimed that in their experiment they had successfully impregnated a female chimp with human sperm. Their goal was to create a more highly evolved primate with a larger brain and one that could potentially speak. But they admitted they didn’t have good plans for it as they were going to use it as a slave by making it drive carts and herd sheep. According to their story, the project fell apart because of the Cultural Revolution, when revolutionaries smashed their lab and destroyed their work. According to their claims, the chimpanzee, which allegedly was three months pregnant, had died before she could come to term. But was there ever a proper successful hybrid?

A Successful Hybrid

While scientists in the United States have been racing against their competitors in attempts to make animal-human hybrids that survived of their own, a Shanghai team in 2003 had beat them to it. The Chinese scientists were the first to successfully create a human-animal hybrid that was developed in a laboratory dish. They fused human cells in rabbit eggs, creating the embryos of a creature that was half-rabbit and half-human. It was also revealed that only a small amount of rabbit DNA was used which meant that whatever came out would have been more man than animal. While to some that might sound like the stuff of nightmares as they try to picture what such a creature would look like, it’s worth pointing out that that the world never got to see what they made. That is because they only allowed the being to develop for a few days before they destroyed it and harvested it for its stem cells.

The Ethics Dilemma

As you can see, the creation of these human-animal hybrids isn’t something from a sci-fi movie but a thing that scientists have gotten pretty close to, and because of it, this has forced us to deal with the ethical questions that many never thought they’d have to deal with. Some scientists have argued that these part-human animals they’ve created will not have easy lives as they will most likely be used to run medical experiments and procedures on as many would consider them less human, and that is a thing that several of the aforementioned examples had already proven. However, it has not been determined where the line between man and animal will be drawn. Many are against such things, even using the embryos just to harvest stem cells, as they see it as playing God, and as violating human dignity. And as scientific advancements go further and further, this will be a topic that will most likely get discussed more and more.
