Canada Global(Web News) Having a brain is so essential to the human experience that it is almost impossible to imagine any life without it. However, many organisms do not have brains, and if we turn the wheel of time back far enough, we may meet our ancestors who had no such thing as a brain.
So the question arises, when and in whom did the first mind in the world come into being?
Sebastian Schmeld, an evolutionary biologist at the University of Oxford, admits the question is a difficult one. It is also difficult to distinguish who has a mind and who does not, because we do not have a precise definition of mind.However, scientists have provided some studies on the evolutionary origins of brains by isolating animals without brains.Sponges, for example, have no neurons, so they were isolated. Similarly, jellyfish and sea anemones have a network of neurons, but they do not have a central nervous system like our brain.
Today there are many species, including some invertebrates such as octopuses, 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’s all done by a single neuron system in the head of an insect.
