Evolution Of Bpedalism Summary

In the article, "The evolution of bipedalism in hominids and reduces group size in chimpanzees: alternative responses to decreasing resource availability" by Lynne A. Isbell and Truman P. Young discussed bipedalism gives the earliest piece of information about the morphological and behavioral dissimilarity between hominids and pongids and countless sequence of events have been put forward for its evolution (389). For instance, selective pressures for bipedalism involves starting to lift items, reliant offspring, food, supplying group members, modifying feeding postures, lowered thermal loading, and higher locomotor efficiency (389). Most of these sequences refer to climatic modification as the cause of the evolution of bipedalism
