Which of the following is a characteristic feature of hominin species?
A
Prehensile tail
B
Quadrupedal movement
C
Bipedal locomotion
D
Opposable thumbs on feet
Verified step by step guidance1
Begin by understanding the term 'hominin.' Hominins are a group that includes modern humans, our immediate ancestors, and other extinct relatives. They are part of the family Hominidae, which also includes great apes.
Next, consider the characteristic features of hominins. One of the most significant evolutionary traits of hominins is bipedal locomotion, which means walking on two legs. This is a key distinguishing feature from other primates.
Evaluate the options given in the problem. A prehensile tail is a feature found in some primates, but not in hominins. Quadrupedal movement refers to walking on four limbs, which is typical of many animals but not hominins.
Opposable thumbs on feet are found in some primates, like certain monkeys, but hominins have evolved to have opposable thumbs on their hands, aiding in tool use and manipulation.
Conclude by identifying bipedal locomotion as the correct characteristic feature of hominin species, setting them apart from other primates and enabling various adaptations such as tool use and complex social behaviors.
