Most humans alive today can trace a very small percentage of their DNA to Neanderthals. However, Neanderthal DNA is slightly more abundant in the genomes of certain populations.
One matched DNA samples provided by Livingston’s mother and sister. Four matched four of the eight men first identified in the 1990s: Jeffrey Jones, Manuel Resendez, Johnny Bayer and Richard Hamilton.
The team found that the noncoding RNA contained two loops, a donor loop that could recognize IS110’s own DNA, and a target loop able to recognize DNA at an insertion site somewhere in the genome.
The DNA of 10 families exposed to the ’80s violence and 22 families to the 2011 conflict was compared to the genetic material of 16 families who left Syria before 1980, avoiding decades of unrest.
