Which of the following is a TRUE statement? the evolution of bipedalism involved a complex series of transitions -- it didn't happen suddenly. Apes walked in a very stiff-legged way, and hominins were much more fluid as quadrupeds, and also better climbers to boot. Natural selection did not operate on the traits that made us bipedal. Nonhuman primates can get faster walking speeds with quick, hopping strides. The arch in hominin feet is super handy for grasping tree limbs.

Which of the following statements is true regarding bipedal locomotion among hominids? arching of the foot has become increasingly less pronounced foot phalanges have gotten longer to facilitate grasping with the feet The big toe has become useless The arches of the foot absorb shock from walking while robust big toe and tarsal bones provide stability

Australopithecines, humans, and even Miocene apes have been bipedal in different ways, yet we assume that natural selection shapes our bodies to be optimally effective and efficient. Is there one best way to be bipedal?
What were some of the factors that led to hominid bipedalism? Choose one correct answer. Bipedalism developed as a result of hominids performing a specific mating dance. Paleoanthropologists theorize that it was an adaptation to life in grasslands. Bipedalism did not occur until Homo habilis, who was upright. Bipedalism allowed for better survival in a forest environment.
