I'm currently reading the book “ The Deep History of Ourselves” by Joseph LeDoux. I find an extract from it about how human language emerged particularly interesting. Researchers point out that the human language emerged in order to gossip. Specifically, living in tribes, people needed to find out relationships among themselves because it was necessary for survival. They found out during the interactions who are trustworthy and who aren't, or which traits should have a mate. Researchers also mention that even today's communications mostly consist of gossiping. Thinking about this subject, I remembered the interesting idea that Richard Dawkins once shared in one of his interviews about poetry. He said that the poetry can be the product of the reproductive instinct. While speaking about it, he told about birds. Singing of a male bird makes female's hormonal background to change, and therefore her behaviour changes too. When it comes to science, some researchers think that it is a byproduct of the instinctive curiosity that is also typical of animals. For example, a rat explores the territory before she begins to eat or to mate. She has an instinctive drive to expand her territory. For humans, this instinct expands over the whole universe because it is a territory that they can potentially acquire.
