DNA and RNA

Can DNA show what our ancient ancestors looked like?

Yes, to a point: Thanks to advances in DNA analysis of the human genome, researchers can determine the eye and hair color of ancestors dead for up to around 800 years. After comparing genomes across thousands of people, scientists have uncovered genetic variations at twenty-four different points in the human genome—all linked to eye and hair colors. Not only is this useful in knowing what your ancestors looked like, but it will no doubt solve plenty of historical controversies and mysteries in which color photos, paintings, or other records are missing.
