Evolution is the process in which populations change over time

Explanation:

The reason evolution is the process in which populations change over time is because evolution reflects the adaptations of organisms to their changing environments and can result in altered genes, novel traits, and new species.

you did not attach the discourse, but i assume it to be the discourse on the origin and basis of inequality among men (the original titile in french is: "discours sur l'origine et les fondements de l'inégalité parmi les hommes"), also know as "second discourse". in this discourse, jean-jacques rousseau emphasizes that private property is the basis of all inequalities.

therefore, what enabled the old regime to maintain as long as it did was private property.
