Conceptual knowledge of evolution and natural selection: How culture affects knowledge acquisition
by Gutierrez, Maria del Refugio, Ph.D., Texas A&M University, 2009, 234; 3400818
Abstract (Summary)

This study examined what effects, if any, cultural factors have on conceptual knowledge of evolutionary theory through natural selection. In particular, the study determines if Latino and non-Latino students differ in their misconceptions of natural selection and, if so, could cultural factors be the reason for the differences. A total of 1179 college students attending eight Hispanic-Serving Institutions in Texas participated in the study. The results revealed that students encountered difficulties in causes of phenotypic variation, i.e., mutations are intentional, and selective survival based on heritable traits. And even though the top four natural selections misconceptions were similar between the Latino and non-Latino students, no statistical significant differences were found between groups.
