Researchers have found a gene in yeast that codes for a myosin protein, which is also coded by gene in humans, what does this similarity at the molecular level in yeast and humans indicate?

a) humans and yeast share common ancestry

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.
