Quizplus · Accepted Answer

All early hominids from Africa older than 2 million years possessed small brains, similar in size to those of apes. They also had other ape-like features such as long arms and curved fingers, which suggest they were adapted to life in trees. Later hominids, such as Homo erectus, had larger brains and began to show adaptations for bipedalism.
