This collection of four essays examines the ways in which biology, as a discipline, reflects ongoing scholarship on gender, race, ethnicity, social class, and sexual orientation. In "Natural Sciences: Molecular Biology," Bonnie B. Spanier examines common ideological distortions in biology, including superimposing stereotypical gender attributes and language onto animals and plants, creating hierarchies of organization with assumptions about power relationships, and claiming that biology determines behavior. In "Feminist Critiques of Biology," Sue V. Rosser discusses the inequities of scientific research and education and ways in which feminist perspectives can be introduced into biology courses. In "Balancing the Curriculum in the Biological Sciences," Joseph N. Muzio discusses the teaching of a Biology of Women course and offers insights on how it affects students' understanding of women's issues and feminist perspectives of science. In "Women in Science and Engineering," Edward B. Tucker points out that while the number of women in science and engineering has increased significantly over the last decade, women have tended to attain degrees and academic positions in life science and psychology rather than in earth science, environmental science, mathematics, and engineering. Each essay contains references. (MDM)
