A recent article talks about some newer thoughts on DNA and the fact that some people may have more than one set of DNA in their body. Chimerism. It offers a puzzle and thought that if this is true for people, could this also be true in other animal species? Is this why we may not find a mutation in some cases when researchers look and don’t locate what they expect? Fascinating and very curious.
