¶ … gender have influenced the historic development of science in the west, as reason and science have long been seen as male traits. Similarly, gender ideals such as the characterization of females as maternal, associated with nature, irrational, and week have been reflected in scientific literature. Today, science continues to be influenced by ideas of gender, as literature reflects gender biases, and female scientists routinely must challenge gender biases. Many of the ideals the influence the historic development science come from the Enlightenment, a time during the 17th and 18th centuries where reason was seen to be a driving force for progress. Enlightened men were rational, and sought happiness, knowledge, and freedom.

The rational affairs of humankind were thought to be left to men, who acted according to intellect and reason, where women were seen as driven more by baser instincts such as emotion.

In time, these ideals of gender norms were subtly changed, as the ideal of manliness began to incorporate that of rugged individualism, hard work, and aggressiveness.

These gender norms reveal a great deal about the importance of gender identity in culture.

Sex is simply the physiological differences that determine male or female (such as facial hair, genitalia, and so on). As such, the association of social concepts with sex is societal and cultural, and not necessarily determined by nature.

Londa Schiebinger, in Why Mammals are Called Mammals reveals how deeply these gender issues have influenced the development of science. Even the basic categorization of the animal kingdom, which lies at the very heart of modern biology, reveals these gender politics argues Schiebinger. It was gender politics that led " addresses the gender politics that led to Linnaeus's careful choice of the term Mammalia, meaning 'of the…
