Scientists Unlock Secrets Of Ancient Human DNA

He Is A Real-Life Chimera

So, what happened to Christopher? Chris became a chimera as a result of the bone marrow transplant, which is a scientific name for persons who have two sets of DNA. The name is derived from a creature in Greek mythology that was a mixture of three animals.

Prior to Chris’ work, forensic scientists were aware that some medical procedures can generate chimerism. But they never looked into where the donor’s DNA replaced the patient’s in the body. The fact that 99% of Chris’s DNA had changed sparked concerns in the medical community.
