Language stands as humanity’s most distinctive achievement, a biological capacity that has shaped our species and enabled the extraordinary complexity of human civilization. Yet despite centuries of inquiry, the questions surrounding language’s origins, its neural substrates, and its relationship to consciousness remain among the most profound and contested in science. How did language emerge in our evolutionary history? What biological mechanisms make linguistic communication possible? How do genes, brain structures, and cognitive processes converge to create the human capacity for symbolic thought and speech?
This book approaches these enduring questions through an integrative lens, drawing together insights from evolutionary biology, neuroscience, genetics, cognitive science, and linguistics. Rather than treating language as purely a cultural artifact or an abstract formal system, we examine it as a biological phenomenon, one that evolved through natural selection, develops predictably in individuals, and rests on specific genetic and neural foundations.
