A new paper pubished in Cell
has serious implications for IDist arguments of "no new information" and "mutation only breaks things".
The researchers have found that a gene responsible for neuron development has been duplicated twice in humans only. One of the copies produces a truncated peptide at high levels which interferes with the original protein. This interference has the result that neurons form more connections and over longer distances.
The duplication etc is seen only in humans. It demonstrates how a duplication of existing information, followed by a "breaking" of the gene can have profound events.
