For neo-Darwinism, new functional genes either arise from non-coding sections in the genome or from pre-existing genes.
He also said that mutations in non-coding portions of the gene, which control regulation, could also render it nonfunctional, which tends to push the number upward.
The functions of these non-coding nucleic acid sequences are only partly understood.
Here we propose an approach to the study of the rate of evolution of functional non-coding sequences at a macro-evolutionary scale.
The rare mutations - which are changes in the non-coding portion of its DNA - can serve as markers, which can distinguish peoples.
