Comparative Anthropogeny (CompAnth) is the study of distinctly human traits and characteristics in the context of comparisons with our closest living relatives, the "great apes." This symposium, the third of CARTA's CompAnth series, will present a collection of distinctive human traits, ranging from molecular, cellular, and anatomical biology to behavioral, societal, and cultural features. Given the large number of human traits for which no counterparts have yet been described in nature, the limitations of the comparative method will also be addressed and alternative approaches to the singularity that is the human phenomenon will be discussed. The goal is a better understanding of human origins and a full appreciation of our species' planet altering effects. (#39281)
