The immage describes the body comparison of two human beings, Australopithecus afarensis and Homo erectsus. The people who are of type walkers and tree climbers are call as Australopithecus afarensis. Similarly, people who are walker and endurance runner are called as Homo erectus.
To start with the comparision with the upper parts of two bodies, we can see that there is a long shout, narrow shoulder, wider chest, long forearms and it also has short and wider waist for type of people who are walker and tree climber. Where as for the peoplw who are walker and endurance runner have balanced head, wider sholder, narrow chest, short forearm and tall with wider waist.
Further more, the lower half of the body there is a small and large hip for Australopithecus afarensis and Homo erectsus respectively. In the same way Achilles tendon have short for tree climbers and long for runners.
Overall, we can observe that the body is completely balanced for Homo electus with stabilized foot arch anch and short toes. Where as Australopithecus afarensis is having unbalanced type body structure with long hands and legs and it has long toes with partial foot arch.
