Philip Lieberman, PhD
George Hazard Crooker University Professor Emeritus, Brown University.
**Philip Lieberman** is the George Hazard Crooker University Professor Emeritus at Brown University. Lieberman's central interest is the nature and evolution of the biological bases of human language and cognition. In essence, his work centers on the evolution of modern human beings since these are among the central attributes that differentiate us from apes. His outlook, therefore, is shaped by principles and procedures of Evolutionary Biology. As Theodosius Dobzhansky noted, "Nothing in biology makes sense except in light of evolution." Conversely, the mark of evolution is evidence in the anatomy and physiology of the human brain and body.
