With AncestryDNA, you or a friend can
Here's how it works: AncestryDNA collected DNA information from groups of people across the globe, "from small tribes in Africa to farmers in the Irish countryside," says AncestryDNA. Once you order the kit, you'll receive a saliva collection tube, instructions and a pre-paid return envelope that you can drop in the mail with your saliva sample inside. The results are compared with everyone in the company's database to see how closely you match with others. You can then explore the results on the company's website.
