Our Ancient Youth

A Perspective on Evolutionary Phylogeny and Ontogeny

By: Robert C. Vannucci, Susan J. Vannucci

Narrated by: Virtual Voice

The major purpose of this monograph is to describe hominin fossils that are the juvenile representatives of the various species of our human ancestral past in the context of the disciplines of ontogeny and phylogeny. Ontogeny is the study of development through the lifespan, while phylogeny is the study of evolution. The book is appropriate largely for upper-level undergraduate and graduate students interested in the fields of developmental biology, neuroscience, and anthropology. The treatise is also accessible to a non-anthropological reader, as it provides some background pertaining to evolutionary principles and chronology. There are two major sections in the book. The first section is related to those critical characteristics that define hominins and to general concepts of ontogeny, and the second is related to the hominin lineage as a series of chronological events. These successive evolutionary stages begin with the presumed earliest hominins and end with the appearance of anatomically modern humans (AMH's) within the past 200,000 years.
