Which of these choices best describes the work of herbert spencer?

I believe the answer is: He compared the development of a society to the evolution of living things.

He was known for comparing society to living organisms because of several similarties:

- Both of them have the abiltiy to grow and develop

- Both of them is consist of smaller parts/structures with their own function

- There is one central control in both of them (for society it is the government, for living things it is the brain)
