Just. WOW.
We take language for granted. This book shares to us some lights of what we call “language”, again, through the evolutionary lenses. This book is amazing, when it comes to explanations, and the basis that helped create the way we communicate. Before anything, I’m just going to say that this review is nothing, but a drop of water compared to the ocean of knowledge the book encompasses.
A signal is something that a living being does advising an action or something to do. This “signal” does not mean anything more than the signal itself: “down”, “up”, “come”, “go”; is has the action just stated in the present, and that is it.
A symbol is a complex thing. To understand a symbol, you must understand beyond place and time; to understand symbol you have to own a different and more complex cerebral wiring, and thus, cognition. Signal is related to mimicking activities, but symbol, goes beyond that.
The book takes several arguments that are found in evolutionary biology, evolutionary archaeology and evolutionary psychology, such as: proactive and reactive aggression, “the bonfire hypothesis”, jaw reduction, gut reduction, fire control, self-domestication hypothesis, sexual selection, ultrasociality, group selection, morality, reciprocal altruism, and shared intentionality, and many more concepts first coined by Pinker, Boehm, Dumbar, Wrangham, Currier, Miller, Hrdy and Tomasello.
This is a book that really makes you think a lot about language, what you are saying, and paints a picture about human evolution and what was like to explain something 50 kya or even 100 kya.
Today, we are living in a place in which we are hijacking information, we are ultra informed, and social media is creating problems in our neural procedures. This is the reason why psychologists such as Jonathan Haidt explain what is going on with today’s youth.
