The issue focused on scientific literature published between 1987 and 2000. Scientists spent five days examining studies showing biological differences between scientists from different backgrounds. These researchers performed experiments with laboratory mice to study chemical reactions that occur during biology. They compared lab experiments with actual laboratory experiments using molecular biologists. Scientists identified research literature studies which presented findings regarding biological differences between scientists of different backgrounds. Scientists tested whether scientists could infer biological differences based on science literature studies. Science literature studies included biomedical literature studies, philosophical literature studies, evolutionary biology literature studies,
