question 35

Multiple Choice

Fossils from different species of the genus Homo dating from 1.7-1.9 mya have been found in ecologically diverse areas across central Asia,China,and Indonesia.These species appear to be closely related to Homo erectus.Which of the following is a likely explanation of these findings?

• A) Homo erectus migrated across the Asian continent and expanded into a new ecological role. These groups became increasingly reproductively isolated from other Homo erectus groups and eventually formed new species in the genus Homo.
• B) Homo sapiens migrated across the Asian continent and expanded into a new ecological role. These groups became increasingly reproductively isolated from other Homo sapien groups and eventually formed new species in the genus Homo that were more like Homo erectus and less like Homo sapiens.
• C) Homo floresiensis migrated across the Asian continent and expanded into a new ecological role. These groups became increasingly reproductively isolated from other Homo floresiensis groups and eventually formed new species in the genus Homo that were more like Homo erectus and less like Homo floresiensis.
• D) Homo neanderthalensis migrated across the Asian continent and expanded into a new ecological role. These groups became increasingly reproductively isolated from other Homo neanderthalensis groups and eventually formed new species in the genus Homo that were more like Homo erectus and less like Homo neanderthalensis.
