Answer:
Sociological School of jurisprudence.
Explanation:
The Sociological School of Jurisprudence believes that both laws and societies are closely related to each other. It states that laws are social phenomenons, therefore they evolve as societies evolve. Laws have a major impact on how societies function, but the laws themselves originate from societies' needs.
For example, less than 100 years ago homosexuality was illegal in most of the world and homosexuals would be punished with jail time or even killed in some countries. Now western societies (North and South America, most of Europe and Australia + NZ) have changed and accept homosexuality as something normal. But there still exist societies where homosexuals are criminals and are still sent to jail or killed.
