The primitive Vilani were not entirely uninterested in biological science. Most food items had to be extensively processed before they could be eaten, a requirement that encouraged the shugilii caste to carefully study the plant and animal species around them. However, since native disease organisms were almost unable to affect the Human body, the Vilani were never motivated to delve deep
into the biological sciences. Even today, the Vilani have only a limited understanding of cellular biology or
the germ theory of disease.
The Imperial Standard Technology is at an early TL7 level for biotechnology and most areas of medical science. Through trial and error, the Vilani have developed advanced surgical techniques, including the ability to perform safe blood transfusions and some major-organ transplants. Their understanding of biochemistry is primitive, and they have not discovered the structure or role of DNA.
