[ link to www.sciencedaily.com (secure)] What makes us human? The answer may be found in overlooked DNA
Our DNA is very similar to that of the chimpanzee, which in evolutionary terms is our closest living relative. Stem cell researchers have now found a previously overlooked part of our DNA, so-called non-coded DNA, that appears to contribute to a difference which, despite all our similarities, may explain why our brains work differently.
"The part of our DNA identified as different was unexpected. It was a so-called structural variant of DNA that were previously called "junk DNA," a long repetitive DNA string which has long been deemed to have no function. Previously, researchers have looked for answers in the part of the DNA where the protein-producing genes are -- which only makes up about two per cent of our entire DNA -- and examined the proteins themselves to find examples of differences."
The new findings thus indicate that the differences appear to lie outside the protein-coding genes in what has been labelled as "junk DNA," which was thought to have no function and which constitutes the majority of our DNA.Savage lol
