Answer to q. 1

Concepts to Consider: The out of Africa hypothesis suggests that modern Homo sapiens
evolved in Africa, then spread to Europe and Asia; the multi-regional hypothesis proposes
that Homo sapiens evolved from diverse groups of Homo erectus in Africa, Asia, and
Europe

Answer to q. 2

Concepts to Consider: Arboreal primates and those primates that evolved from them
typically have binocular (stereoscopic) and very sharp vision, grasping hands, a welldeveloped
sense of balance, a prehensile or grasping thumb, and may have a prehensile tail as
well.
