-Australopithecines were the earliest hominids that lived about 5-6 MYA.The australopithecines were able to walk upright, or have a bipedal stance. They also had opposable thumbs. Both of these features helped hem survive in the open savannah.  About 6 MYA, the tropical jungles in Africa began to dry up and forests began to shrink. The group that became humans were forced to move further out onto the open grassland. The new adaptations, such as bipedalism and opposable thumb, helped them survive.
