The complete genome of the octopus was read
Scientists have mapped the complete genome of the octopus, i.e. found out all the base pairs in the octopus's DNA - the octopus's DNA consists of thirty chromosomes and contains two billion and eighty million base pairs. -
Octopuses are among the most intelligent animals in the world - although octopuses and humans have no significant evolutionary commonalities because their common ancestors lived in the depths of the ocean 750 million years ago - just as humans did for 750 million years. And the evolution of the octopus is diverging—an octopus nonethelessIntelligence is strikingly similar to that of humans and other intelligent mammals—hence why octopuses are used as model organisms in neuroscience research.
Although there is a great distance between octopuses and mammals in evolution, and the brains of octopuses are very different from those of mammals, the intelligence of octopuses suggests that the brains of octopuses have more or less all the functions of any intelligent brain. The plasticity of the mammalian brain—especially the octopus brain—occurs(i.e., changes in the brain's wiring as a result of external stimuli and sensory experiences) are of great interest to experts—in addition, octopuses have certain abilities not found in mammals—for example, if octopuses If a part of the body is cut off, it will regenerate in a few weeksScientists are increasingly interested in sequencing the octopus genome to better understand octopus evolution and to understand which genes in the octopus's DNA control organ regeneration. Help to do
Octopus DNA is slightly shorter than human DNA—human DNA has about 3.2 billion base pairs, compared to 2.8 billion base pairs in octopus DNA—but human DNA has 23 chromosomes. divided into pairs, whereas octopus DNA consists of thirty pairs of chromosomes—human DNAThere are about 20,000 genes in the DNA, while the octopus has 33,000 genes
Scientists at the University of Vienna in Europe have now completed mapping the octopus genome and successfully read all of its base pairs - enabling us to know how many genes are in octopus DNA. And which genes are on which chromosomes - with this information we not only did the biology of the octopuswill be able to develop a better understanding but also compile the evolutionary history of the octopus - this research will also help to understand the evolution of the octopus and its close relatives such as cuttlefish, snails and other closely related animals.
