Binary is the ultimate guide for understanding and dismantling the sex spectrum, the new cultural belief that sex exists on a continuum and that male and female are social constructs.

By analyzing its ten most popular arguments, Zachary Elliott reveals how the tenets of the sex spectrum deny evolution, development, and genetics. 

Using biology literature, the book provides the reader with a scientific understanding of how the two sexes are universal phenomena and how complex genetic networks consistently result in a simple yet profound outcome: male or female.
