According to Yuval Noah Harari in his book SAPIENS, the key that set homo sapiens apart from the other animals about a million years ago can be found in the use of language. Most animals have speech related to specific needs: mating, danger, and pleasure. Some such as monkeys learned to deceive, a false alarm to clear the pack from a food source. Most sounds are memorized codes such as the alphabet soup of acronyms relating to our government, CIA, FBI, USDA, etc. Like the nouns in any language, the list could go on nearly forever.
Homo sapiens discovered relationships between these coded sounds, much like verbs, actions between them. On to higher forms of communication: abstractions (unseen forces in the universe) and hypothetical’s (if thens and what ifs.)
Abstract language coupled with a more basic interaction inherited from animals—rule of the alpha male over social groups, modern time extended to include alpha female—coupled with a basic human need for self identity. Who am I in relation to the other members of my social group. Gossip. These judgmental statements require abstract words—feelings, values, attitudes, appraisals, put-downs.
Social groups are still ruled by alpha males, but the lower hierarchy continually jostles for position, how do I fit in relation to those closest to me. Conspiracy theories—recently labeled fake news—add juice to the conversation.
