Brain is the main organ of any living being but there are some living beings which are devoid of brain.
It is impossible to imagine the life of any living being without a brain, but it is also said that there are many living beings in our world who actually do not have a brain, however, scientists around the world know about life (human and non-human). Continues to investigate, which sometimes leads to surprising facts.
A large number of researchers are also engaged in research regarding the brain of living things and trying to know which living thing in the world is the one whose brain came into being first?
Foreign media have quoted Sebastian Schmeld, an evolutionary biologist at the University of Oxford, as saying that the question and the distinction between who has a brain and who doesn’t is difficult. Because we don’t have a precise definition of mind.
About 600 million years ago, a group of animals evolved with only the front and back of the brain, Dr Sebastien said. The front is where the nervous system crystallizes because it is the part of the animal that receives direct experience from the environment.
A complete nervous system probably first developed in a long, slender insect, he added. We believe that all the other animals with brains after that are derived from the nervous system of insects.
Do you know these interesting and dangerous scientific facts?
Today there are many species, including some invertebrates such as the octopus, that have brains similar to ours. The octopus brain can also control higher functions such as cognition, behavior and memory. It’s complex and amazing, and it all came about from just a system of neurons in the head of an insect.
