Vedclass · Answer

(B) The evolution of primates towards humans involved several key morphological changes. One of the most significant adaptations was the development of an opposable thumb,which allowed for better grasping and tool manipulation. In early primates,the thumb was often parallel to the other fingers,but the evolutionary trend towards hominids involved the thumb becoming opposable. However,among the given options,the presence of $32$ teeth is a characteristic feature of the dental formula found in Old World monkeys,apes,and humans $(2:1:2:3)$,which represents a specialized evolutionary trait compared to the higher number of teeth in more primitive mammals. Therefore,$32$ teeth is the correct feature associated with the lineage leading to humans.
