What are you talking about? Baboons, macaques, gibbons, great apes, capuchins, howlers, or squirrel monkey do not conduct arranged marriages, nor marriages at all for that matter. Looking at evolution and how it formed us and we find very little of arranged marriages.
Arranged marriages also limits men and women equally (the definition is the bride and groom are selected by individuals other than the couple themselves) so I am not sure what argument you are trying to make in the first place.
