Worked Solution & Example Answer:The out-of-Africa hypothesis A - VCE - SSCE Biology - Question 14 - 2010 - Paper 1
Step 1
D. proposes that Homo erectus evolved into Homo sapiens in Africa before migrating to other continents.
Answer
The out-of-Africa hypothesis posits that modern humans (Homo sapiens) originated in Africa and migrated to other parts of the world. This theory suggests that Homo erectus, an ancestor, evolved into Homo sapiens specifically in Africa before these populations dispersed across the globe. Unlike the multiregional hypothesis, which claims that Homo sapiens evolved simultaneously in different parts of the world, the out-of-Africa model emphasizes a single origin followed by migration.
