When humans started writing, our brains rearranged themselves to take on the challenge of reading.
The history of reading is long and complicated, but this much is obvious: our brains learned to read when we began to write.
Of course, it’s hard to pinpoint when exactly humans first invented writing. But it seems that, long before there were any alphabets with different letters representing distinct sounds of a particular language, humans began to record information through visual symbols.
One of the earliest examples can be found in the Blombos Cave in South Africa. There, archeologists have uncovered stones marked with cross-hatched lines they believe to be almost 80,000 years old. In this case, it’s not known what the lines represent, but there are other examples of early human cultures using similarly marked stones, shells, and clay pieces to record economic transactions. So there’s good reason to believe that the lines in the Blombos Cave are not just random scribbles, but carry meaning.
The discovery that you could represent things in the world through abstract symbols, and thereby record events for future generations, was a revolutionary idea. So revolutionary, in fact, that it ended up changing our brains.
The key message here is: When humans started writing, our brains rearranged themselves to take on the challenge of reading.
Our brains are made up of billions of connected nerve cells, or neurons. These neurons have the amazing ability to restructure themselves and form new connections, depending on how we use them. Scientists call this phenomenon “neural plasticity.”
When humans first learned to read, new neural pathways formed in their brains that allowed them to detect and decode intricate visual symbols at rapid speed. If you remember what it was like to learn to read as a child, you will appreciate how powerful this transformation can be. From not knowing what to make of those strange markings on the page, your reading skills soon become so automatic that you can’t not read the words in front of you.
Neuroscientists have shown that, when humans look at unfamiliar, letter-like shapes, we only activate a small part of the visual areas located in the back of our brain. But when we see letters we know, our brain’s activity nearly triples. Not only does it engage more of the visual areas, but it also fires up parts of the brain specialized in language processing, hearing, and abstract concepts.
One of the most important new connections that first formed in our ancestors’ brains as they learned to read was between a part of the back of the brain called the angular gyrus – an area responsible for association – and areas involved in object recognition. This neuronal breakthrough was the basis for some of the first complex writing systems, which we’ll get to know in the following blinks.
