Biology is the term for the branch of science that studies living organisms and the processes by which they live. The Island of Yuriba had no formal concept of the science of Biology before the arrival of modern humans during the Founding Era. However, the culture does have it's own theories on the basics of life that have been adapted and applied to the principles of Biology that are now taught at Rinkei Gakuen.
The Three Domains
Yuriban adaptations of this system have yielded slightly different results. As it is a biological fact that all life on Yuriba is Female, from the smallest organism to humanoids themselves, the Eukarya domain is reclassified as the Femina domain in Yuriban Biology.
