Evolutionary Breakthroughs in Learning and the Role of Language

Throughout the evolutionary history, there have been significant breakthroughs in learning. Vertebrates started with reinforcement learning from their own actual actions. Mammals developed trial and error learning. Primates introduced learning from understanding the intent of others. With the advent of language, a new breakthrough emerged where individuals could learn from another's imagined outcomes. This ability to share imagined outcomes through language enabled vicarious trial and error, allowing for collaborative planning and execution of tasks. Language also facilitated the transmission of ideas between individuals, leading to the evolution of cultural principles and the accumulation of ideas across generations. This process of idea evolution, or memes, represents a secondary layered evolution that has propelled the complexity of human societies to unparalleled levels.
