Genes offer a deeper peek into our ancestry
For ordinary folks buying the kits, what you get is a deep tour of time, starting in Africa more than 60,000 years ago, keyed to major groups of genes that show up in everyone's ancestry. From these beginnings your genes track, in a sense, ancestral wanderings of groups of genes that point to past migrations tens of thousands of years in and out of Africa. "We all start off in Africa, that's clear from the genes," Wells says.
