British media: Studies have shown that the "jump gene" of octopus is the key reason for high IQ behavior

[Global Times Comprehensive Report] Scientists have discovered that octopus is smarter than ordinary vertebrates. A new study may find a central cause: octopus has a "jump gene" similar to humans.

According to the British "Daily Mail" reported on the 27th, the "BMC Biology" magazine recently published a joint research result of more than 20 scholars around the world. They used gene sequencing technology to detect the molecular composition of active genes in the octopus nervous system, and found the "jump gene" in the same position in ordinary octopus and California octopus brain. Human genome and octopus genome contain a large number of "jump genes", they can move in the genome through the "copy and paste" mechanism. In the human body, such "jump genes" are closely related to learning, memory and other cognitive abilities. In the octopus brain, the "jump gene" is also located in areas related to cognitive capabilities. This may be that octopus often shows high IQ behavior. The key reason.

Scientists say that this similarity between humans and octopus may be a case of convergence evolution, that is, two far -distance species are the same needs, and their molecules independently show the same evolution trend. (Feng Guochuan)
