Arms and Legs : The development of arms and legs in humans is tied to our ancestors’ transition from aquatic to terrestrial environments. These limbs helped in movement and manipulation of the environment, which was crucial for survival. Absence of Tails : Humans, along with other great apes like chimps, gorillas, and orang-utans, do not have tails 1 . This is likely due to the shift towards an upright posture and bipedal locomotion 1 3 . In many animals, tails serve as a counterbalance and aid in movement, especially running 1 . However, as humans and their immediate ancestors started walking upright, the tail became less necessary for balance 1 3 . Moreover, a tail could have been a hindrance to the type of locomotion seen in apes, such as swinging from branch to branch 1 . Interestin...
