The aim of this study is to compare how the authors of Zoology textbooks of the second half of 19th century and early 20th century made the didactic transposition of anthropological studies on the human races for these textbooks. The results show differences in the typology and anthropological characteristics used to describe the human races. It was also noticed the presence of statements related to the concept of biological determinism because the authors valued physic, morally and intellectually the Caucasian race instead other races.
