Resource Type
Description
This tutorial describes how scientists determined that all living humans originated from populations in Africa. Some of these populations migrated out of Africa less than 100,000 years ago.
The Click & Learn introduces students to the genetic concepts and tools that scientists used to trace the migration routes and origins of modern human populations. In particular, it focuses on the use of genetic markers to identify small genetic differences among human populations throughout the world and reconstruct migration paths.
The accompanying worksheet guides students’ exploration.
Student Learning Targets
-
Use evidence to support the claim that all modern humans originated in Africa.
-
Explain the strengths and limitations of using different types of evidence to support claims about human migrations.
