A ACORNS and I interview. a Average scores of both majors and advanced majors for the CINS, b key concepts in the written ACORNS assessment and interviews c naive ideas used in the ACORNS and interviews, and d Non-adaptive ideas used in the ACORNS and interviews. Though advanced majors show a slight increase in key concepts used and a slight decrease in naive ideas used, this trend is non-significant. However, advanced majors do use significantly more non-adaptive ideas in their evolutionary explanations compared to majors
