The animals and plants in the world today, including us humans, have evolved over a long period of time. As human intelligence continues to advance, the types of things humans can create are beyond calculation. But can you imagine a day when humans can act as "creators" and determine the breeds and forms of animals? What we are going to talk about next are two animals created by humans, which will definitely subvert your understanding.
Whenever we talk about artificial creatures, the cloned sheep "Dolly" comes to mind. The emergence of Dolly was a leapfrog turning point in biotechnology in human history. After so many years of continuous research and experimentation, the biotechnology possessed by humans now is completely incomparable to that of that time. Therefore, the two artificial animals mentioned below are no longer simple cloning technology .
First one: Belgian Blue Bull
The Belgian Blue Bull once caused a heated discussion among many netizens on the Internet. This is because it has muscles comparable to those of human bodybuilding champions. People also called it the "bodybuilding champion" of the cattle world because of its strong muscle outline. Another name for it is the Belgian devil tendon beef. As the name suggests, it has a devilishly strong figure and is rated as the strongest cow in the world. The Belgian Blue Bull has been much larger than other cattle species since birth. An adult bull can grow to weigh 1.2 tons and be over 1.5 meters tall.
The Belgian Blue Bull appeared in the public eye in the late twentieth century, and its origin can be traced back to the late nineteenth century. At that time, a cattle farmer put Shorthorn cattle and Charolais cattle in captivity, and then the two types of cattle were mated. Unexpectedly, the offspring they produced was a breed with extremely lean meat content, called beef cattle. So farmers began to continuously mate these two types of cattle to give birth to beef cattle, and then let the beef cattle continue to mate with each other, and so on for the next generation of beef cattle. In this way, after more than a hundred years of continuous cultivation, the Belgian Blue Cow with a body covered with tight muscles was born.
The body of Belgian Blue cattle has such a high muscle content. This is all due to the continuous reduction of "myostatin" in these cattle during the continuous breeding process. By the time Belgian Blue cattle have reached this point, this substance has been consumed and no longer exists. As a result, muscles can grow freely in the bodies of Belgian blue cattle. According to records, they can gain nearly 1.5 kilograms of weight in one day, and almost all of it is muscle weight. Therefore, its meat is more delicious and chewy than that of other cattle, and its lean meat production is several times that of other cattle. It is a good source of beef supply for humans, so the meaning of the existence of Belgian Blue cattle today is to provide high-quality beef to humans.
The second one: Israeli Hairless Chicken
Chicken appears on the human table in various cuisines. It can be said that chicken has become an indispensable ingredient in human recipes. The thick and messy feathers of chickens are a very troublesome problem for humans, so when they continue to develop machines for plucking chicken feathers, people also turn their attention to the chickens themselves.
In the 1950s, someone in the United States discovered a chicken with naked skin and no feathers. After research, it was found that this kind of chicken was caused by a genetic mutation, so researchers from Belgium used this kind of chicken to mate with ordinary chickens with a try. After constant breeding, this edible chicken with bright red skin and no feathers was born, and was named the Israeli Hairless Chicken.
The meat quality of Israeli hairless chickens is not inferior to that of other chickens, and the egg production speed is not far behind other chicken breeds, or even higher. Moreover, Israeli hairless chickens have strong adaptability. Ordinary chickens can only grow at a temperature of about 20 degrees Celsius, and their bodies do not show any discomfort even when the temperature rises to 30 degrees Celsius. According to research, this characteristic of Israeli hairless chickens may have a certain relationship with global warming. However, this undoubtedly greatly reduces the cost of raising chickens for humans, especially in the hot areas of Africa and the Middle East.So far, more than a thousand Israeli hairless chickens have been tested in the laboratory and it has been confirmed that they will not cause any harm to the human body. Therefore, this chicken breed that is easy to handle, easy to raise, and delicious has been put into captivity and sold in some areas. Perhaps in the future, the Israeli hairless chicken will rely on its many advantages to become the most abundant chicken breed in captivity.
From the above two artificial animals, we can know that the ultimate purpose of human beings to continuously cultivate them is to serve human beings, and whether this method of artificially interfering with the laws of nature and rewriting biological genes is feasible, we have also drawn a huge question mark for this. In this era when the genetic engineering is in full swing, we are guiding life to continuously evolve in a direction that is beneficial to us. It is undeniable that we have indeed made great profits, but while making profits, should we think about some issues from the perspective of these creatures? What do you think about this?
