Each scientific study emerges in its own particular time and marks a new step in the development of human thought. Big History materialized to satisfy the human need for a unified vision of our existence. It came together in the waning decades of the twentieth century, in part, as a reaction to the specialization of scholarship and education that had taken hold around the world. While this specialization had great results, it created barriers that stood in contrast to a growing unity among our global communities. These barriers were increasingly awkward to bridge, and, thus, Big History emerged as a successful new framework.
