Genome analysts at 23andMe have devised a new way to reveal the secrets inside your DNA. Their latest test will reveal how many of your genes come from Neanderthals. Be warned: some people have a lot of Neanderthal in them.
It's now confirmed that early humans and Neanderthals interbred, and this practice was widespread enough that all non-African people alive today carry some fraction of Neanderthal genes. With the help of Eric Durand, who worked on both the first draft of the Neanderthal genome and the genome for the newly discovered Denisovan people, 23andMe is now offering a test to determine just how your DNA stacks up with the Neanderthal genome.
