Grossmont College Early Human Migrations & Fossil and Genetic History Paper

Early Human Migrations

Introduction

The fossil and genomic record tell us that our species originated in Africa around 200,000 years ago (These numbers might now go back further). The first 100,000 years were spent in Africa and soon after our species began to expand into different world regions.

What you are doing

Your task will be to explore the complex fossil and genetic history of modern humans as they left Africa for the first time.

For this webquest you will only be able to choose one of the following world regions:

  • The Americas (you will be including both North and South)
  • Europe

All the above world regions have complicated population histories that are the result of a number of populations that have come together to form the present population. What insight do genomic studies of ancient fossils and modern populations give us in reference to the number of founding populations that form your chosen world region?

Before you begin your task make sure you read the following items.

Tips for success

  • Please keep your answer to only what is asked in the assignment.
  • I recommend composing your content offline in a text editor and then copy and paste the text into your reply post. If something happens you will have an offline copy of all of your hard work!
  • I highly recommend using Google Docs (Drive) to compose offline, as Google plays well with web-based forums. If you are using Microsoft Word to compose offline, you may need to do some editing to the format when you paste it into the reply.
