Genes needed for human learning, memory, aggression and other complex behaviors have been found to have originated about 650 million years ago. [사진=게티이미지뱅크]Now, I think it’s a natural function of the brain because anyone can learn anything and remember something naturally, but let’s go back to the original question.
Since when the hell did humans have complex learning functions such as learning, remembering and processing things? Since the beginning of human beings? The results of a recent study on this issue are interesting.
Dr Roberto Feuda of the Neurogenetics Group, Department of Genetics and Genome Biology, University of Leicester, UK, and collaborators at the University of Friberg, Switzerland, recently discovered that genes required for learning, memory, aggression and other complex behaviors originated about 650 million years ago. It was published in Nature Communications.
It is the area of the brain that humans want to do something about. Monoamines such as serotonin, dopamine, and adrenaline act as neuromodulators in the nervous system, controlling and regulating complex behaviors and functions such as learning and memory. In addition, the fact that the brain processes basic needs such as sleeping and eating has been well known in the scientific community for a long time.
However, the origin of how and when the genes necessary for the production, detection and degradation of these monoamines arose is not well known. To uncover this origin, the researchers used computational methods to reconstruct the evolutionary history of the human genome.
The researchers found that most of the genes involved in monoamine production, modulation and reception came from a bilaterian stem group. This also shows the evolutionary origin that humans and other animals have continued complex behaviors by controlling the brain nervous system by monoamines.
The researchers predict that this evolutionary way of regulating neuronal circuits could have played a key role in the Cambrian bioburst known as the Big Bang. The Cambrian Explosion refers to a geological event in which various types of animal fossils suddenly appeared about 542 million years ago. For interaction with the environment and survival at the time, the flexibility of brain neural circuits became active and developed, causing various changes in the lives of humans and animals today.
“This study reveals the origins of how humans have been able to perform multidimensionally complex behaviors, and how the same brain neurons regulate and control multiple areas, including reward, addiction, aggression, eating and sleep,” said Dr. Feuda. It can help clarify whether or not.”
