The origin of human existence has been a debated topic for a long time. For some of you, it must have crossed your mind about what happened before human existence appeared. The topic that usually appears in biology lessons has actually been answered by the emergence of the theory of evolution proposed by Charles Darwin. It is true that Darwin said that our ancestors were apes who evolved into humans. Of course, this is believed by many people because this theory is taken based on the discoveries of the bones of ancient animals and humans that have gradually improved their biology over millions of years so that they become the human they are today. But something is missing in this theory.
The evolutionary process from apes to humans is still flawed, which until now the missing link has not been found. This is what causes many people to oppose Darwin’s theory of evolution. They then did some research to prove the truth.
One of the most
recent research was carried out by scientists at the Kunming Institute of Zoology and the Chinese Academy of Sciences. These scientists also collaborate with expert researchers from the University of North Carolina, United States.
This research is something that shocked the world. These scientists took a human brain gene which was then implanted into a monkey. This study was aimed to examine the evolutionary development of human intelligence. These researchers inserted a version of MCPH1, which is believed to be a gene that plays an important role in human brain development.
that run the test were required to remember the color and shape of a certain amount of information that was given through a screen. At the same time, an MRI scanner scanned them. From this process, only 5 monkeys left that survived.
After various series of studies were carried out, the results were obtained. The scientists found that the monkey brain took longer to develop. However, one type of monkey involved in the study, the rhesus monkey, had better brain performance, especially on tests of short-term memory.
These results were then written and published in the National Science Review Journal based in Beijing. The results showed that primates are not transgenic humans, nor are humans included in the ape species. Humans have their own uniqueness, different from the monkeys studied.
this research received a lot of criticism from various parties. Those with differing opinions consider this research unethical. A bioethicist from the University of Colorado, Jacqueline Glover even delivered a satire for these desperate researchers. He told the researchers to go to the monkey planet in their imagination. Glover also said not to create beings that cannot have meaningful life for any purpose.
Another critic also emerged from a researcher named Larry Baum who works for the Center for Genomic Science, University of Hong Kong. He said that rhesus monkeys have a different genome from us.
Similar research has also been conducted in January. Chinese scientists cloned an animal with five monkeys that were genetically engineered to have sleep disorders. The animal then develops signs of health problems such as anxiety and depression.
