One of several intriguing characteristics of chromosome 8 is a fast-evolving region, where the mutation rate appears to be highly accelerated in humans and human-like species, in contrast to the rest of the human genome. The Nature paper is titled "The structure, function and evolution of a complete chromosome 8." The completed assembly fills in the gap of more than 3 million bases missing from the current reference genome. The entire sequence of chromosome 8 is 146,259,671 bases. This linear assembly is a first for a human autosome - a chromosome not involved in sex determination.
