Early Human History

The human species is relatively new to the planet in geologic terms. With origins reaching back only a few million years, the rise of humans from primate ancestors is a remarkable evolutionary success story. Early Humans traces the beginnings of the human species, its success and adaptability, and the development of such innovations as human language and culture.

Inspired by Sarah DiGregorio’s harrowing experience giving birth to her premature daughter, Early is a compelling and empathetic blend of memoir and rigorous reporting that tells the story of neonatology - and explores the questions raised by premature birth. The heart of many hospitals is the Neonatal Intensive Care Unit (NICU). It is a place where humanity, ethics, and science collide in dramatic and deeply personal ways as parents, doctors and nurses grapple with sometimes unanswerable questions: When does life begin? When and how should life end?

Most scientists believe the evolution of humans has a history nearly as long as life itself. Anatomically modern humans and all other life that has existed on the planet first came about from the single-celled microorganisms that emerged approximately four billion years ago. Through the processes of mutation and natural selection, all forms of life developed, and this continuous lineage of life makes it difficult to say precisely when one species completely separates from another.

The Cro-Magnon were Homo sapiens, and the most defining characteristics of the species are the cultural traits that begin to show in the archaeological record. Tools were beginning to be made from multiple materials, and these people would often travel long distances or trade to acquire specific materials for tools. Symbolic material became increasingly common among them, as cave paintings, figurines, shell beads, pendants, and even early burials were more common with modern humans than Neanderthals.
