Everything in the world has its own structure and shape. Whether it is plants, animals, or even inconspicuous bacteria, they all have their own characteristics and different living habits, so that they can form a colorful world. Over the years, there have been many scientists and biologists who have given mankind a better understanding of itself.

There is a view that humans are originally a kind of animals, but they belong to a high-level category and also have a lot of animality. But it is fundamentally different from other animals. It can not only use tools, but also create tools. It can be said that there is a close relationship between humans and animals, as well as other species.

So, are there any similarities between human and animal genes, and what are the differences? This is a question that many scientists have been studying. In the past, we have heard of transplanting animal organs into human bodies. As early as 1984, a little girl named Baby Fae had a heart problem. In order to save her, doctors implanted a baboon's heart into the little girl. As long as she can be rescued, it means that human science and technology can make great progress.

But sadly, the little girl died on the 20th day after the baboon's heart was implanted, her immune system was attacked, indicating that implanting animal organs into humans was not feasible, at least at the time. Conversely, what would happen if human organs were transplanted into animals? Can human and animal genes communicate?

This idea has already been implemented. In Japan, scientists have already carried out this crazy experiment, they have transplanted human organs into animals. Once this experiment was carried out, it caused a lot of discussion. Some people believed that there was reproductive isolation between humans and animals, and this approach would not work.

In March 2019, a scientific team from the University of Tokyo, Japan, applied for the hybridization test of human and animal cells, in other words, it wants to grow human organs in animals. We all know that in the process of transplanting human and human organs, rejection will inevitably occur, so it is even more difficult to avoid this situation between animals and humans.

Japanese scientists will first modify the genes of animal fertilized eggs, and then implant human cells into animals for in vitro cultivation. Japan says the experiment could solve the problem of human organ transplants. So, what was the final result of the experiment? Today, the experiment still has no final conclusions. However, we can guess its outcome from the phenomenon of transplanting animal organs into humans, and the process will certainly not be smooth.
