Which group includes only bipedal animals?
A.Primates
B.Hominins
C.Lesser apes
D.Hominids
Help me pls- I don't got much time-
The correct answer is B. Hominins, as they are the only group that includes only bipedal animals. Primates and lesser apes can be quadrupedal or arboreal. Hominids, on the other hand, include both bipedal and quadrupedal animals.
its b
Yes, that is correct.
To determine which group includes only bipedal animals, we need to understand the characteristics of each group and identify the one that consists solely of bipedal animals. Here are the definitions of the groups mentioned:
A. Primates: This group includes all primates, including humans, monkeys, and apes. While some primates may display bipedal locomotion (walking on two legs), not all members of this group are exclusively bipedal.
B. Hominins: Hominins are a sub-group of primates that include modern humans and extinct human-like ancestors. Bipedalism is a defining characteristic of hominins, as they are the only group that consists exclusively of bipedal animals.
C. Lesser apes: Lesser apes, also known as gibbons, are a group of small apes. Gibbons are not exclusively bipedal; they are primarily arboreal and use a combination of brachiation (swinging from branch to branch) and bipedal walking.
D. Hominids: The term hominid refers to a broader group that includes great apes (gorillas, chimpanzees, and orangutans) in addition to hominins (humans and human-like ancestors). Not all hominids are exclusively bipedal.
Therefore, the correct answer to your question is B. Hominins, as this group includes only animals that walk upright on two legs.
